Bug bite purple bruise: The request could not be satisfied


17 Signs Your Bug Bite Is Something Serious

Summer is most people’s favorite season for a reason: Its days are packed with backyard barbecues, pool parties, and long days at the beach. But while the dog days provide sunshine and sangria, they also contain a nuisance found not during the rest of the year: bugs. And it’s not just that they’re annoying, either; unfortunately, many of these irritating insects also have the potential to cause serious harm, thanks to their venom and the diseases they carry.

So if we can’t avoid bugs altogether, then what is there to be done to prevent a trip to the hospital? Well, for starters, memorize the signs we’ve compiled here that a bug bite is doing some serious damage to your body. And once you read up on the warning signs to look out for, partake (safely) in one of the 20 Summer Hobbies That Will Change Your Life.

Though swelling is a common reaction to most bug bites, excessive swelling can be a cause for concern. If you notice that the area around your bite is continuing to swell after a few days—or even that the swelling is extending to other parts of the body—then it’s vital that you seek medical attention to identify the type of bite and receive treatment accordingly. And for more ways to stay in tip top shape, don’t miss the 20 Warning Signs Your Liver Sends You.


Thanks to your body’s autoimmune response, most insect bites will swell at the sight of puncture, but few will bruise unless there’s something serious going on. Should a mysterious bite start to turn black and blue, it’s likely that something is happening inside your body that needs to be checked out, like an allergic reaction to a mosquito’s saliva or even a staph infection.


Though uncommon, bug bites can cause severe allergic reactions that result in fatal heart attacks. If you ever notice a bug bite on your body and subsequently begin to experience chest pain, head to the hospital right away. And for more health tips, read up on the 20 Healthy Living Rules You Should Live By.


According to the Mayo Clinic, bites from dangerous arachnids like the black widow and brown recluse generally clear up on their own, but in severe scenarios, these venomous stings can cause difficulties breathing and ulcerations at the site of penetration. These symptoms are indicative of a more serious issue, such as anaphylactic shock, and they shouldn’t be ignored.


Feeling dizzy after getting bitten by a bug could mean that you are allergic to said pest, according to the University of Texas’ University Health Services. In other cases, it could also mean that you’ve been bitten by a black widow spider—and either way, you’ll want to seek medical attention.


Nausea can accompany several serious bug bite complications, including Lyme disease, Chikungunya virus, and venomous spider bites. Luckily, most of these complications can easily be treated by a medical professional, so long as you address them as soon as they start showing symptoms. And if you live in any of the 20 U.S. Cities That Are Bug-Bite Central, make sure to be extra careful.

Never ignore a bullseye rash surrounding a bug bite. In most cases, this rash is a telltale indication of Lyme disease, a tick-borne illness that, if left untreated, can cause arthritis, neurological disorders, and heart palpitations.


If your temperature starts to spike after getting stung by an unknown bug, then you might be dealing with a brown recluse spider bite. Unfortunately, these spiders have venom more dangerous than that of a rattlesnake, and so if there’s even a slight possibility that you’ve been bitten by one, you should head to the doctor immediately.


If you come back from an exotic vacation to a country like Brazil or China and begin to experience profuse sweating coupled with other symptoms like a high fever and diarrhea, you might be dealing with malaria. Because vaccinations to prevent malaria are required before traveling, it’s unlikely that you’ll ever come down with this mosquito-transmitted illness, but it’s best to beware of the warning signs nonetheless. And it’s not just mosquitos that you have to worry about while abroad: You also need to steer clear of these 20 Foods Doctors Always Avoid While Traveling.


Yet another reason to protect yourself from mosquitos in the summertime is Dengue fever. Uncommon but possible to contract in the United States, this illness can cause everything from pain behind the eyes to severe headaches—and, as it progresses, it can result in bleeding from the nose and gums, circulatory system failure, and liver enlargement. In order to prevent these unpleasant symptoms, make sure to use these 15 Genius Ways to Outsmart Mosquitoes This Summer.

Headaches can be indicative of several things, including chikungunya virus. Transmitted by female Aedes mosquitoes (of course), this infection has no prevention or cure, but doctors can prescribe pain medicine to make you more comfortable as the virus passes.

Immediately after getting bitten by a bug, it’s normal for your body to fight back. For the first few days, you might notice that the skin around the bite is hot to the touch—but if the skin remains inflamed and warm after several days, you could be dealing with an infected bite that requires antibiotics.


Lymph nodes only swell up if the body is fighting off an infection—so if any of the glands on your body become enlarged after getting eaten alive by a bug, it’s likely that this is the result of an infection. And depending on the type of bug that bit you, you could be suffering from everything from West Nile virus (thanks to a mosquito) to a bad reaction to a black widow bite.


There’s a difference between normal fatigue and exhaustion that won’t subside. On the one hand, it’s normal to be tired after staying out all night and getting just a few hours of rest. But if you’re sleeping for 12 hours a night and are still waking up exhausted, then you might be dealing with one of several illnesses, like Lyme disease, chikungunya, or Ross River fever. Whatever the case may be, it’s best to get yourself checked out, as chronic fatigue can severely impact your day-to-day life. And if you need help sleeping soundly, try these 40 Tips for Better Sleep on Summer Nights.


Any and all bug bites can cause a severe allergic reaction. And in the case of most of these reactions, you will almost immediately experience a severe swelling of the lips, tongue, and/or throat, which, if left untreated, can lead to difficulty breathing and even a closing of the airways entirely.


Stomach pain is never a sign of something good. When coupled with a bug bite, this cramping could be a sign of a more serious issue, such as an allergic reaction, Babesiosis, or West Nile virus. And if your abdominal pain is coupled with vomiting and other symptoms on this list, then you should head to the doctor immediately to avoid further complications.


In a study published in the journal Quality of Life Research, scientists found that 41 percent of adults with Lyme disease experienced sleep disturbances, and 60 percent experienced night sweats and chills. During the early stages of Lyme, having trouble sleeping is common, and it certainly shouldn’t be ignored. And to learn about which bugs to be on the lookout for, read up on The 35 Most Dangerous Bugs in America.

How To Tell If A Bug Bite Needs Medical Attention

The Question: When does a bug bite require serious medical attention?

The Answer: Sometimes that pesky mosquito bite needs a little hydrocortisone cream and time to heal. But occasionally, it’s not so simple and instead requires serious medical attention. While most bug bites and stings are harmless, some can be dangerous if not treated properly — especially if you have an undiagnosed allergy to a particular bug venom or if that bug is a disease carrier.

The summer months seem to be stocked with extra critters crawling and buzzing around us, upping the chances that you, a friend or a family member might need a dermatologist’s expertise. Here’s how the experts determine the difference between a nuisance and a health concern that requires attention.

One of the first steps to differentiating between a minor and serious bug bite or sting is to work through some of the key symptoms. “Significant pain, swelling, and bruising are all signs that a bite may be serious,” said Joshua Zeichner, a dermatologist and assistant professor at Mount Sinai Medical Center in New York City. “Swelling that is spreading significantly beyond the initial bite may also be a sign of a serious issue.”

Of course, in extreme instances, a bug bite reaction can be grave enough to result in an ER visit. Margaret Parsons, a dermatologist and associate clinical professor of dermatology at the University of California, Davis, advises people to pay attention to symptoms like the sensation that your throat is closing, chest pain, a persistent racing heartbeat, dizziness and vomiting, and head to the emergency room if you experience any of them.

Treatment for bug bites that don’t fall into the emergency room-worthy category can run the gamut from topical ointments or an over-the-counter antihistamines to more aggressive treatments, such as antibiotics, anti-allergy medications, or even skin debridement, which is the medical removal of dead, damaged or infected skin to promote the healing of surrounding healthy skin, according to Zeichner. Debridement is only necessary if the bite or sting has turned into an open wound in which necrotic (dead) or ischemic (low oxygen content) tissue is preventing it from closing and healing properly. Necrotic tissue can also promote bacteria growth, which leads to further inflammation and increases risk of infection. You’ll need to see a doctor to determine if debridement is a viable treatment plan for you and, if so, which type.

According to the American Academy of Dermatology, the most common bites and stings in the United States come from mosquitoes, fleas, spiders, bees, wasps, hornets, biting flies, mites, ticks, fire ants and bedbugs. During the summer months, Zeichner is most cautious about tick bites due to their ability to carry lyme disease, and spider bites that can cause serious, localized skin destruction depending on the species. Several mosquito species are also a concern when it comes to carrying and transmitting the West Nile virus, malaria, dengue fever and chikungunya. If you’re spending time in a high-tick or mosquito area, here’s what you’ll need to watch out for:


If you develop a red, target-shaped rash after being bitten by a tick, Dr. Parsons warns that this symptom could indicate a Lyme disease infection, which must be treated with antibiotics. Ticks can also carry Rocky Mountain spotted fever, a bacterial infection signified by a red or black spotty rash that spreads, which also requires immediate treatment.


Malaria symptoms typically appear within a few weeks after being bitten by an infected Anopheles mosquito, which can include recurrent high fever, shaking chills and profuse sweating along with headaches, vomiting and diarrhea. Be sure to seek emergency medical attention if experiencing these severe symptoms.

Dengue fever rarely occurs in the continental United States, but when it does, it’s due to an infected Aedes mosquito. Symptoms like (but not limited to) high fever, severe headaches, pain behind the eyes, rash and mild bleeding (such a nose bleed, bleeding gums, or easy bruising) usually begin four to six days after infection and can last up to 10 days. The female Aedes mosquito specifically can also transmit chikungunya, which is characterized by symptoms similar to Dengue fever like fever, severe joint pain and muscle pain, headache, nausea, fatigue and rash.

West Nile virus is a tricky one since between 70 and 80 percent of people don’t exhibit symptoms after they become infected. But in severe cases, patients will typically experience headaches, body aches, joint pains, vomiting, diarrhea and/or rash, and hospitalization can be necessary to provide fluids intravenously and pain medication.

Minimizing the risk of suffering serious bug bites, however, is the best method of prevention and a relatively easy task.

“Wear long sleeves and pants, and in light colors so you can see if there are any bugs on your skin,” said Zeichner. “And use bug spray or citronella candles if you are going to be outside.”

Mosquito Allergy: Symptoms, Diagnosis, and Treatments

Mosquito bites are annoying, but is it possible to have a mosquito allergy? To understand how you might be exposed to an allergen that triggers a reaction, let’s look at what happens when you get bit.

Smith Collection / Getty Images

Mosquitoes are flying, biting insects that are closely related to flies and gnats. Only the female mosquito feeds on humans, and she needs a blood meal in order to produce eggs.

During a feeding, the female mosquito bites the human skin and injects saliva. The saliva contains various proteins that prevent the blood from clotting, as well as proteins that keep the blood flowing into the mosquito’s mouth.

Reactions to Mosquito Bites

Many of the mosquito saliva proteins can cause immune reactions, including allergic reactions. Typically, however, most people have a variety of reactions to mosquito bites, and the symptoms change over time, depending on the number of bites a person receives.

These reactions can include both immediate and delayed swelling, and itch around the bite area. These reactions tend to decrease in frequency after being bitten by mosquitoes over many years.

Generally, people with the above-described reactions are not diagnosed as being “mosquito allergic.” This term is reserved for people with more severe or unusual reactions, such as those described below.

Severe Reaction—Skeeter Syndrome

Reactions more severe than the typical itchy red bump experienced by most people as a result of a mosquito bite occur less commonly. These may result in blistering rashes, bruises, or large areas of swelling at the bite sites.

People who experience extremely large areas of swelling after a mosquito bite (such as swelling of most of an arm or leg, for example) have been dubbed as having “skeeter syndrome.”


In rare situations, some people may experience anaphylaxis (the most serious type of allergic reaction) after being bitten by mosquitoes. Other people may have experienced whole body urticaria and angioedema (hives and swelling) or worsening of asthma symptoms after being bitten.

Typically, these symptoms occur within minutes after a mosquito bite, compared to skeeter syndrome, which may take hours to occur.

Who Is at Risk

People who are at higher risk of developing an allergy to mosquito bites include:

  • Those with frequent outdoor exposure, such as outdoor workers or frequent outdoor exercisers
  • Those with low natural immunity to mosquitoes, such as young children and visitors to a new area where they have not been previously exposed to the type of mosquito present
  • Those with certain immunodeficiencies, such as AIDS or certain cancers (such as leukemias and lymphomas)


The diagnosis of mosquito allergy is based on a positive skin test or RAST using mosquito whole-body extract. Testing for mosquito allergy should only be performed in people who have a history of reactions more severe than the typical small, red, itchy bumps experienced by most people.

That said, commercially available allergy testing is apparently only able to identify 30% to 50% of those who have a true mosquito allergy.


The treatment of mosquito allergy falls into three different categories: the treatment of local reactions, the treatment of severe reactions (anaphylaxis,) and prevention. Let’s look at each of these separately.

Local Reactions

Most localized reactions can be treated with the use of topical corticosteroids, such as hydrocortisone cream, as well as with oral antihistamines. In fact, Zyrtec (cetirizine) has been shown to reduce local reactions to mosquito bites when taken before being bitten.

Some have suggested that those with mosquito allergy use Zyrtec on a daily basis during the summertime when mosquito bites are most likely to occur. Make sure to talk to your doctor before you make a regular practice of this, as any medication may have side effects.


The treatment of anaphylaxis, which only rarely occurs as a result of a mosquito bite, should be treated in much the same way as anaphylaxis to insect stings. With severe reactions such as this, your pediatrician may recommend carrying an EpiPen as well as other measures to decrease the likelihood of a reaction.

There is limited evidence suggesting that allergy shots may reduce severe reactions to mosquito bites, however, they are not a widely accepted treatment at this time.


The prevention of mosquito bites is the main goal for those with mosquito allergy. These measures include:

  • Avoid areas infested by mosquitoes (such as swamps and tall grassy areas).
  • Remove or treat areas of standing water (empty out or treat swimming pools with chlorine).
  • Wear long-sleeved shirts and pants if exposure to areas containing mosquitoes is planned.
  • Avoid cologne and scented lotions when going out-of-doors.
  • Apply a commercially-available mosquito-repellant on exposed skin, such as those containing DEET (N, N-dimethyl-3-methyl-benzamide). DEET in concentrations of 10% to 30% can safely be used on the skin of children older than 2 months of age. However, repellents can cause side effects, including eye irritation, dry skin, rash and possible allergic reaction. Use the lowest concentration that is effective for you and reapply as needed.
  • Treat clothing, camping tents and other fabric with permethrin (an insecticide), but do not apply directly to the skin.
  • Since mosquitoes are attracted to body odor, skin temperature, and carbon dioxide production, limiting strenuous exercise and sweating when in areas infested by mosquitoes may reduce the number of bites.

A Word From Verywell

Thankfully, annoying and itchy reactions to a mosquito bite are much more common than a true mosquito allergy. Those who have a true allergy should see an allergist and discuss the best treatments for their particular symptoms. Anyone who has a severe allergic reaction should be prepared to recognize anaphylaxis and consider allergy shots.

What we did not bring up here is a reason to protect yourself against mosquito bites whether or not you have an allergy. While malaria, yellow fever, and other mosquito-borne illnesses are uncommon in most developed countries, diseases such as West Nile virus (and its variants) may occur anywhere.

Spider Bites and Bee Stings: Symptoms and Treatments

For anyone who spends time outdoors, bites and stings are almost inevitable. Mosquitos, ticks, ants, spiders, bees, wasps — all of these tiny creatures use their mouths or stingers to defend themselves or, in some cases, to grab a meal. But luckily for humans, bites and stings from insects and spiders are usually just uncomfortable, not medically significant.

However, some people are allergic to the venom of certain insects or spiders and can have severe, even life-threatening reactions to bites or stings. Additionally, certain insects and arachnids — like mosquitos and ticks — can transmit disease or cause infection through their bites.


In some cases, bites or stings can be painful. For example, bites from fire ants and stings from hornets, bees or wasps will likely get the attention of the victim. But some bites and stings are subtler, like those from mosquitoes, mites, fleas or ticks, which don’t typically hurt. However, in some cases these painless bites can cause infection or disease, which may lead to more severe symptoms, according to the National Institutes of Health (NIH).

Ultimately, symptoms will depend on what kind of critter bit or stung you and how your immune system reacts to the venom (or other substances) released during the bite or sting, according to the NIH.

Most insect bites or stings generate only minor skin symptoms such as itching, pain or swelling around the site, as well as burning or tingling. Delayed effects, which can appear within hours or days of a sting or bite, include painful joints, swollen glands, hives or fever, according to the Mayo Clinic.

In the case of ticks, symptoms can be more severe if the bite results in an infection or the transmission of a disease, such as Lyme disease or Rocky Mountain spotted fever. According to the NIH, symptoms of such tick bites include:

  • Apnea and/or difficulty breathing
  • Blisters
  • Rash
  • Severe pain at bite site
  • Swelling at bite site
  • Weakness
  • Uncoordinated movement

While the bites of most spiders are not medically significant to humans and cause only mild, local skin reactions, more severe reactions can also occur. According to the U.S. Centers for Disease Control (CDC), spider bite symptoms may include:

  • Raised welt with a pinpoint-sized dot in the center
  • Pain, itching or rash
  • Muscle pain or cramps
  • Profuse sweating
  • Headache
  • Nausea or vomiting
  • Chills and fever
  • Allergic reactions

In addition to the symptoms listed above, those who are allergic to particular insects or spiders may also experience a localized reaction when stung or bitten. Such a reaction may include swelling of the entire joint where the bite or sting occurred, according to Dr. Susan Schuval, chief of the pediatric allergy and immunology department at Stony Brook Children’s Hospital in New York. In extreme cases, those allergic to certain insects or spiders can experience anaphylaxis — a severe, whole-body reaction to the chemical toxins present in an insect or spider’s venom — Schuval told Live Science.

Anaphylaxis is a life-threatening reaction that requires emergency care, according to the National Institutes of Health (NIH). Call 911 if reaction signs include:

  • Difficulty breathing or shortness of breath
  • Facial or mouth swelling
  • Abdominal pain or nausea
  • Difficulty swallowing
  • Pale, moist skin that may appear blue
  • Hives
  • Confusion or disorientation
  • Weakness or dizziness
  • Fast, weak pulse

Types of insects and spiders that bite

Many common insects bite without provocation — or because they’re hungry — including mosquitoes, fleas, mites, flies, bedbugs, fire ants or ticks. Others, such as wasps, bees and hornets, sting when they feel threatened.

Most spiders are not aggressive and will only bite a human if they are surprised or threatened. Such bites usually result in nothing more than a red spot and some itching or swelling, according to Rick Vetter, a retired research associate of entomology at the University of California, Riverside.

“Spiders have venom which is evolved for paralyzing prey; it’s made for reducing activity or overcoming the neurophysiology of an insect. That’s one reason why spider bites have very little effect on humans,” Vetter told Live Science.  

In fact, many spiders have fangs that are too small to pierce human skin. Only a few spiders in the United States have venom toxic enough — and fangs large enough — to cause a medically significant bite in humans. These include the brown recluse and black widow, whose bites can be dangerous to humans and even fatal in some cases.

Brown recluse spiders are usually found in Midwestern and Southern states, according to the CDC, and are also called violin spiders because of the characteristic violin- or fiddle-shaped marking on their heads. These spiders have six equal-sized eyes (in contrast to the typical eight) and are about an inch long.

Symptoms of a brown recluse spider bite include:

  • Deep blue or purple area around the bite, surrounded by white and red outer rings
  • Burning, itching, pain or redness that may develop within hours or days
  • Ulcer or blister that turns black
  • Fever
  • Rash
  • Nausea or vomiting

Black widow spiders are usually found in southern and western parts of the United States, though they live throughout North America. Small, black and button-shaped with a characteristic red hourglass marking on the abdomen, black widows release a toxin that can damage the central nervous system.

According to the University of Maryland Medical Center, symptoms of a black widow spider bite include:

  • Double fang marks at the site
  • Immediate pain, swelling, burning and redness
  • Headache and dizziness
  • Rash and itching
  • Cramping and rigidity in the chest, stomach, back and shoulders
  • Anxiety and restlessness
  • Eyelid swelling
  • Weakness or paralysis, particularly in the legs
  • Excess saliva or eye tearing
  • Nausea and vomiting

Care & treatment

Most bites and stings require only minimal treatment. If a stinger is present, remove it by scraping a credit card or other straight-edged item across the stinger, according to the NIH. Use a pair of tweezers to remove a tick. If at all possible, you should try to safely recover the insect or spider that bit you, or at least try to identify it, according to Vetter. This will help healthcare professionals determine the best treatment option should you need medical attention.

All insect bites and stings should be washed with soap and water for several minutes. According to the Mayo Clinic, other treatments can include:

  • Applying ice to reduce pain and swelling and absorption of the venom for 15 – 20 minutes every one to two hours
  • Applying calamine lotion, hydrocortisone cream, or topical benzocaine for itching and swelling
  • Taking antihistamines containing diphenhydramine (found in the brand names Benadryl or Tylenol Severe Allergy) or chlorpheniramine maleate (in Chlor-Trimeton and Actifed).
  • Wiping the bite or sting area with alcohol or a cool damp cloth with water from a nearby river or spring while hiking or camping

In some cases, a large local reaction can affect the entire joint of the limb that was stung or bitten. In these cases, a doctor may prescribe histamine, as well as oral steroids, according to Schuval. Those with a systemic, or whole body, reaction to the venom of certain insects may undergo venom immunotherapy treatment, in which the patient receives a series of shots containing the venom of the insect (or insects) to which they are allergic. This treatment can reduce a person’s risk of having a systemic reaction to insect venom from 60 percent to less than 10 percent, according to Schuval.

Antivenins are available to treat bites from many of the world’s most venomous spiders. Suspected spider bites should receive prompt medical attention if they result in severe symptoms. If the wound from a suspected bite becomes inflamed or infected, you should also see a physician, as this may be indicative of a skin infection or other condition not caused by a spider or insect, according to Vetter.

For those who are aware of allergies to certain types of bites and stings, it would be advisable to carry an epinephrine. Matthew Lau, chief of the Department of Allergy and Immunology at Kaiser Permanente Hawaii, said a single-dose epinephrine injector should be used if symptoms such as trouble breathing, lightheadedness or hives occurs, and to take a second dose if one is available and symptoms don’t improve within 10 to 15 minutes. Allergy shots could also be beneficial to those looking to reduce their allergic sensitivity of future bites and stings.

James Baker, an emergency medicine specialist from Kaiser Permanente Baldwin Park, provided a few home remedies for spider bites, including making a baking soda paste (diluted 1:3 with water), applying table salt to a wet washcloth and applying to the bite area, applying activated charcoal diluted with water, or applying a starchy potato that has been grated or shredded directly on the bite wound. These home remedies have been tested and have appeared to be effective at drawing out toxins and providing antiseptic and anti-inflammatory properties.

Pain relievers such as ibuprofen can help reduce the pain and potentially slow full allergic response (anaphylaxis) in order to buy some time while waiting for a 911 response, according to Joshua Kugler, chair of the Emergency Services Department at South Nassau Communities Hospital.

Preventing insect bites

Those who are allergic to the venom of certain insects, like bees, should practice what Schuval called “bee avoidance measures.” These include avoiding the nests of insects, not wearing perfume outdoors and leaving your yellow shirts in your closet, she said.

Because mosquitos and ticks in many parts of the world can carry diseases or cause infection, it’s recommended that people spending a significant amount of time outdoors protect themselves against these insects. To limit your exposure to mosquito and tick bites, wear clothing that covers your arms and legs. If you are in an area where these insects are prevalent, use a bug spray containing 5 to 7 percent DEET, a chemical compound known to keep certain insects at bay, according to Jonathan Day, a professor of medical entomology at the University of Florida.

If you’re concerned about using DEET on yourself or young children, products containing essential oils — known as botanicals — can also be used, Day told Live Science. However, DEET is still effective when sprayed on clothing instead of directly on the skin and should be used if you are spending a significant amount of time in active mosquito and tick habitats, he added.

Those who live in areas known for poisonous spiders should always be vigilant and avoid disturbing them, according to Baker. Preventive measures include carefully removing cobwebs and spider webs from dark places, such as garage corners, wood and rock piles, tires, old furniture and piles of old clothes and newspapers. Regularly cleaning living areas and keeping doors and windows closed helps prevent spiders from coming inside to areas that are easily accessible by children and pets. Spiders are also drawn to their food supply areas: where other insects live. Using insecticides or essential oils to kill or prevent insects in these areas can deter spiders from inhabiting there. Insecticides that contain active ingredients such as pyrethrin and allethrin can deter or kill spiders, but the spiders often will need to come into direct contact with the chemicals. Candles and electrical appliances designed to keep insects away may also help with spiders as these tools drive away the insects spiders prey upon. However, these tools, as well as DEET, do not work directly on spiders.

Baker said the best way to prevent spider bites is to avoid spiders, as they typically only bite when they feel threatened. He recommended that spiders be brushed off and not crushed if they do get on skin. Actual spider bites are rare and often attributed to other bug bites or skin infections.

Images of Bite or Sting, Arthropod (Pediatric)


As one of the most frequent causes for visits to the doctor’s office, insect bites and/or stings are quite common among infants. While bites and stings on an infant are typically just an inconvenience, some reactions can be life threatening. The severity of an insect bite will vary from child to child, and only a small minority of infants develops this severe reaction (anaphylaxis).

It is important to get immediate medical attention for a severe reaction to a bite or sting, such as those that may occur with stings from bees, wasps, and hornets. Most insects (such as ants, mosquitoes, flies, spiders, ticks, and mites) do not cause such a severe reaction.

A bee will occasionally leave behind a stinger attached to a venom sac. It is important to try and remove it as soon as possible. Wasps, on the other hand, do not leave their stingers in the skin after stinging, which means they can sting more than once.

Who’s at risk?

Infants of both sexes are just as likely to get stung. While an infant may be seriously affected by an insect bite, it is not always true that other family members will be equally affected by the same type of bite. Heredity does not play a factor in how any given person will react to a bite or sting.

Signs and Symptoms

Insect bites usually appear as small, itchy, red bumps, occasionally with a blister. Infants may be more prone to developing a blister than older children. Some insects, such as fire ants, can cause a painful and itching raised area containing pus (a pustule).

Flying insects tend to bite exposed areas not covered by clothing, while some bugs (such as fleas) focus on the lower legs. Bedbugs prefer the head and neck area, often biting several times in the same area and leaving a group of lesions.

Common reactions to arthropod stings may include:

  • Redness, pain, and swelling
  • Severe reactions such as facial swelling, difficulty breathing, and shock
  • Fever, hives, and painful joints (though these reactions are not as common)

Very few spiders cause severe reactions. The black widow spider may cause only a mild reaction at the bite site, but pain, stiffness, chills, fever, nausea, and abdominal pain may follow within a few hours. Similarly, the bite of a brown recluse spider may cause a severe skin reaction after a few hours, with redness, pain, blistering, and ulcers forming, as well as fever, nausea, and fatigue.

Self-Care Guidelines

For stings:

  • Bees may leave a stinger behind. Try to gently scrape the stinger off with a blunt object, such as a credit card.
  • Wash the wound with soap and water.
  • Apply an ice pack or cold water for a few minutes.
  • Take acetaminophen (Tylenol®) for pain and an antihistamine (diphenhydramine or chlorpheniramine) for itching, as needed.

For insect bites:

  • Wash with soap and water.
  • Apply cool compresses.
  • Use antihistamines to relieve itching and take acetaminophen (Tylenol®) for pain.
  • Apply 1% hydrocortisone cream to help reduce the itching.

For ticks (still attached):

  • Using tweezers, grasp the tick as near the skin as possible, and pull firmly
    until it releases.
  • Swab the area with alcohol or soap and water.
  • Save the tick for identification, if needed.
  • Wash the area with soap and water, and then apply 1% hydrocortisone in case a reaction occurs.

When to Seek Medical Care

Some insect (arthropod) bites/stings are more dangerous than others. If you suspect your child might have a black widow or brown recluse spider bite, apply ice to the area and seek medical assistance immediately.

Symptoms of these bites include:

  • A deep blue or purple area around the bite, often with a surrounding white
    area and a red outer ring
  • Abdominal pain
  • Headache
  • Fever
  • Fatigue
  • Nausea
  • Muscle stiffness

If the area of a tick bite becomes red or swollen, or if the affected area spreads outward, seek medical help to check for Lyme disease.

When dealing with stings, watch out for symptoms such as:

  • Hives, itching, or swelling in areas beyond the sting site
  • Swelling of the lips or throat
  • Tightness in the chest or difficulty breathing
  • Hoarse voice or tongue swelling
  • Dizziness or loss of consciousness

Treatments Your Physician May Prescribe

Depending on the type of insect bite and how your child reacts to it, your child’s doctor might treat him or her in a number of ways.

For insect bites:

  • Prescription topical corticosteroids
  • Muscle relaxants
  • Pain medicines
  • An antidote against the specific toxin (antivenin)
  • Antibiotics
  • Sometimes surgery at the affected area, if the insect bite is severe

For stings:

  • Antihistamines or corticosteroids
  • Epinephrine
  • Antihistamines
  • Corticosteroids
  • Injected (intravenous) fluids and oxygen for shock (anaphylaxis)
  • Injectable epinephrine if your child is known to have severe allergic reactions
  • Procedures to stimulate the immune system (immunotherapy) to reduce the chance of repeated severe reactions

Mosquito Bites: Allergy Reactions & Symptoms

Mosquitoes are vectors of malaria, encephalitis and yellow and dengue fevers. Their bite can also cause allergic reactions in sensitive individuals.

Why Do Mosquitoes Bite?

Female mosquitoes have piercing mouthparts through which they extract the blood of a host. The protein from gathered blood is used in egg production. Males do not bite and feed on blood. Instead, they get their energy from plant nectars and other sweet substances found in their habitat.

After puncturing the skin with their mouthparts and feeding on blood, mosquitoes leave hard, itchy bumps. In the blood-feeding process, mosquitoes inject saliva into their host which creates the reactions that cause bite symptoms.

Most mosquito bites are harmless and the symptoms subside in a few days. Some discomforting symptoms include swelling of the bite site, soreness, and bleeding. While mosquitoes are an itchy, uncomfortable nuisance, the important problem arising from mosquito bites is transmission of viral or parasitic diseases.

Symptoms & Reactions

Many mosquito species are such stealthy biters that most people never notice their first mosquito bites. Other species are ferocious biters whose bite is moderately painful. The symptoms of mosquito bites include:

  • A puffy, white bump appearing a few minutes after the bite often with a small red dot in the middle of the bump
  • A hard, reddish bump, or bumps, that shows up about a day after a bite
  • Swelling around the bites
  • Small blisters instead of hard bumps
  • Dark spots that look like bruises

In children and people with immune system disorders, mosquito bite symptoms may include:

  • A large area of swelling and redness
  • Low-grade fever
  • Hives
  • Swollen lymph nodes
  • Headache

Always seek the advice and assistance of a physician when dealing with mosquito bites.


While not particularly painful, the bite of a mosquito can create physiological responses in humans. When a mosquito inserts her proboscis through the skin, her saliva creates a small, red bump. These bumps produce mild to severe itching in many people. Some people may become less sensitive to mosquito saliva through repeated exposure, while others may develop allergic reactions.

 Symptoms of an allergy include blistering and inflammation, as well as asthma like reactions. Mosquitoes also carry diseases such as yellow fever and dengue fevers, malaria and encephalitis and are capable of passing them from host to host.

In most cases, a mosquito bite produces a red, itchy bump, which can bleed if scratched. Those with mild reactions to a mosquito bite can take antihistamines to reduce itching and swelling. Consult a physician before taking any new medications. Over time, some individuals develop immunity to the saliva of a mosquito and do not experience any symptoms at all upon being bitten.

Severe Symptoms

People who spend a great deal of time outdoors or already have compromised or weak immune systems are especially susceptible to mosquito allergies.

More severe symptoms include:

  • Blistering rashes
  • Bruises
  • Excessive swelling
  • Anaphylaxis
  • Hives
  • Asthma attack

In the event of a severe allergic reaction to a mosquito bite, a medical professional should be contacted immediately.

When spending time outside, individuals with known or suspected mosquito allergies should cover their skin in khaki or beige clothing, as mosquitoes are not as attracted to these colors. Because mosquitoes may be attracted to certain smells present in soap, shampoos and lotions, these should be used in moderation and unscented varieties may be less attractive.

Mosquitoes are most active from dusk until dawn. If possible, avoid being outside during these times.

Risks Associated With Infections

As with most insect and spider bites, the risk of secondary bacteria infection exists. In addition, there is a risk of disease transmission from mosquito bites.

How To Identify Bite On Pets

Excessive scratching and minor swelling may be some of the indications of mosquito bites on pets. Much like people, animals may experience allergic reactions to mosquito bites caused by allergic compounds in the mosquito’s saliva.


The use of insect repellents is recommended by the Centers for Disease Control and Prevention (CDC). Repellents should not come into contact with the eyes and mouth, and special care should be taken when applying repellent to small children. The use of citronella or insect repellent may be effective in avoiding bites.

Bite Treatment

After receiving a mosquito bite, a cold compress can be applied to the affected area in order to reduce swelling. Mild antihistamines and anti-itching compounds relieve itching . Anti-inflammatory medications such as ibuprofen or naproxen can also be used. A paste made from baking soda and water may prove effective, as will calamine lotion.

Contact your physician before taking any new medications. If you experience more severe symptoms following a mosquito bite, contact a medical professional immediately.

Do Mosquitoes Die When They Bite?

Mosquitoes and ticks are both public health pests and vector pests. As public health pests, they can transmit diseases reportable to and tracked by the CDC, and as vector pests, they are able to transfer diseases to humans. This means that mosquitoes and ticks are not simply annoying pests because of their bites – they are pests that should not be ignored, given their potential to possibly cause more serious health problems.

Mosquitoes can transmit diseases such as:

  1. Eastern Equine Encephalitis (EEE) – Aches and fever are symptoms of EEE, which can also cause brain infections.
  2. Malaria – Signs of possible Malaria are fever, vomiting and diarrhea.
  3. West Nile virus – Symptoms of West Nile virus can be aches, rashes, severe headaches and fever.
  4. Dengue fever – Vomiting, rashes and a fever are common signs of Dengue fever. Another symptom is severe headache.
  5. Zika virus – Along with a fever and itching rash, Zika virus can also cause joint and muscle pain.

Ticks can transmit diseases like:

  1. Lyme disease – Signs of Lyme disease include fatigue and joint pain. Sometimes Lyme disease can even cause brain inflammation.
  2. Rocky Mountain spotted fever – Symptoms can include fever, aches and vomiting. Sometimes these symptoms are accompanied by neurological changes.
  3. Colorado tick fever – Fever, muscle aches severe headaches and nausea are all possible symptoms of Colorado tick fever.

Mosquito and Tick Hot Spots on Your Property

You can take steps to help reduce mosquito and tick populations on your property by working with your pest management partner to minimize conducive conditions for each pest. By doing so, you can help reduce the habitats where they thrive. To make these changes, you must first identify mosquito and tick hot spots, which include:

  • Building entrances – Ticks thrive in grasses and trees that make up your property’s landscaped areas. Landscaping close to your building entrance allows ticks to hitch a ride onto incoming customers and employees.
  • Pools, ponds and water fixtures – Mosquitoes love moisture and can breed in as little as a bottlecap full of water, making these fixtures an enticing attractant.
  • Outdoor eating areas and kitchens – These areas contain not only the landscaping and greenery ticks love, but also additional water and food, extending an even warmer invitation to mosquitoes.
  • Playgrounds – Surrounded by greenery, playgrounds are also home to other pests, like rodents and rabbits, which can bring ticks with them. These areas are especially important to monitor to keep families safe.

Mosquito and Tick Prevention Tips

To help prevent mosquitoes and ticks from harming your customers, employees and business, consider taking proactive measures. Simple outdoor upkeep can help keep these pests at bay, such as maintaining landscaping; minimizing water build-up; and clearing away brush, fallen leaves, logs and other items they may use as shelter. Adding fans to outdoor areas with heavy foot traffic can help deter mosquitoes further, since they are weak flyers.

Further preventive measures include installing screens on windows and doors to keep pests from entering your building, installing traps in discrete areas and creating a 3-foot wide barrier between trees and grass using wood chips or gravel. Last, consider planting mosquito-repelling plants such as citronella, marigold, mint or lavender.

Hiring a professional to handle mosquitoes and ticks can take the pressure off of you and your employees. In fact, Orkin can help develop a customized plan including a comprehensive inspection, habitat modification, production application as needed and ongoing monitoring and maintenance for your property’s needs. With our assistance, you can do more than help protect your customers and employees – you can help protect your business.

How to understand which insect has bitten you

“VM” tells how to find out exactly who bit you and what to do to suffer from bites less.

They buzz, squeak, scurry. For-dol-ba-li. But – summer is red, where to go. It was also printed by Pushkin: “Oh, summer is red, I would love you, if it weren’t for dust, dirt, not mosquitoes and flies …” What to do – not only us, but also insects like a wonderful time of the year.

Of course, not all insects bite us, but many.And then the bite site hurts and itches, sometimes the bite provokes allergy attacks. And it is very important to immediately understand who actually bit you.

Sometimes there is no need for this definition – the culprit is already obvious. And sometimes you don’t immediately understand who it was that behaved so unfriendly. We will try to figure it out.


The pain of a bite appears almost instantly. As a rule, the bite looks like this: a point, around it is a pale spot, and around it is redness with severe swelling.Several bites can cause severe allergies, which are accompanied by weakness, itching, and sometimes numbness of the bitten leg and arm.

Unlike bees, wasps can sting a person as many times as they want – their sting does not remain in the body of the bitten one. By the way, the sting of a wasp is perhaps the sharpest object in nature! That is why, by the way, it is more correct to say about the wasp that it “stung” and not “bit”. The person himself can provoke the aggressive behavior of wasps – with sharp movements, and women – with the scent of perfume.Do not scent in nature, this arouses unhealthy interest in insects …

Antihistamines must be taken immediately! And if you are allergic, do not hesitate to seek medical help. Bites to the head and neck are especially dangerous.

The bite of this insect is remembered for a lifetime. It hurts like hell. The overwhelming majority of people have a fever from a hornet bite, the bite swells terribly and does not itch, namely, it hurts – as if the limb was cut off, doused with boiling water, etc.p. Hornets are aggressive, impudent, they attack if they are trying to drive them away – in a word, this is one of the most serious enemies of man in nature. True, in our latitudes, no one dies from bites when providing assistance, but in Japan, for example, where hornets are incredibly poisonous, in some years up to forty people die from their bites.

In fact, hornets do not bite people often, and only if they sense the danger posed by them. If, for example, someone threatens their nest, waves their hands, tries to slap a newspaper – which, by the way, is absolutely useless.Hornet venom is also more “protective”. But many of its components are found in the venom … of the rattlesnake! Thus, phospholipases and orientotoxin cause destruction of cell walls. Their contents flow into the intercellular space, a focus of inflammation arises, and then – if the walls of blood vessels are damaged – hemorrhage occurs, followed by suppuration.

Phospholipases are just an integral component of snake venom. And acetylcholine is a neurotransmitter that activates nerve endings.When it gets into the tissues, there is a feeling that the nerve nodes are either beaten with a hammer or cut with a knife. There is also a large amount of histamine, which provokes allergic reactions, and biogenic amines initiate an increase in heart rate and activation of respiration. What is curious: in general, the toxicity of the hornet venom is less than the toxicity of the venom of the same bee, but the pain of the sting is much more acute and prolonged.


All the hard work is good, but they bite. The bite is a bright red dot, sometimes with “gnawing” a piece of skin.A tight, hot, sometimes painful red swelling is quickly poured around the bite – a cake. As a rule, the bite is accompanied by a burning sensation, gaps, empty spaces can form inside the “cake”, sometimes small scars remain in this place as a keepsake.


The bite is accompanied by fiery itching, edema. The bite site is very hot, by the way, this is called hyperthermia; in the center of the edema, sometimes a double point is visible, sometimes a cut. It gets worse from scratching.

To relieve swelling at the site of the bite, you need to apply something cold to the center (a piece of ice wrapped in a handkerchief from the freezer), then wipe the site of the bite with an alcohol solution (if you take alcohol, dilute it 1: 1).After that, you need to make a saturated soda solution or even turn the soda into wet porridge and apply it to the damaged area. Then the bite site needs to be smeared with ointment – have fenistil, lifeguard or trimistin in your country first aid kit. If a dense bump has formed at the site of the bite, you need to treat this place with alcohol and make a lotion of ointment (sinaflan) for at least an hour and a half. It is possible, if there is no ointment, to crush the antihistamine, slightly dilute it with water and apply the gruel.

To relieve severe itching, if there is no ointment, you can use ordinary potatoes – attach a wedge or grated raw potato in the form of a lotion.Apple cider vinegar helps – dilute it slightly and lubricate the damaged area. If there is nothing at all in the stash, spread the bite with toothpaste. In nature, if you understand plants, you can quickly prepare an infusion of a series, attach a plantain.


A small insect that brings about-oh-very big trouble is the midge. She sits in the grass, flies out in a flock and does not bite, but gnaws out a piece of skin, then sucking blood and lymph from the wound. Midge bites cause, for the most part, just a wild allergic reaction.Since the midge usually bites unprotected legs and arms, they are the ones who suffer the most, but insect bites on the lips, neck, and eyes are especially dangerous. Swelling from midge bites can be scary! A bite in the eye or eyelid is especially sensitive. It seems to a person that there is some foreign body in his eye, tears are flowing like a river. After the “attack” of insects, shortness of breath, blisters may occur, and lymph nodes often enlarge and become painful. The edema can last for a very long time, it all depends on how many bites there were.Wounds heal too badly, fester, itch and itch. A characteristic sign of a midge bite: redness and a drop of dried ichor at the site of the bite.

If the swelling is very severe, sometimes you have to resort to diuretics. Otherwise, bites require the same treatment as other insect bites.

By the way, midges really do not like the aroma of vanillin. Sometimes she runs away from him with more horror than from aerosols. Preparing a fragrant repeller is simple: dilute crystalline vanillin in water, pour the solution into a spray bottle and treat the skin surface.


In recent years, the hawk moth is increasingly common in the Moscow region. This creature, completely safe for humans, has a proboscis with which it sucks nectar out of flowers. When there is nothing to suck out with its proboscis, the hawk moth “rolls” it, and “rolls it out” when needed. The hawk moth’s wings flutter so often that a “force field” is created around the insect. There are a lot of such insects in the south; there they are called playfully “kotsalo-pezalo” and they compose all sorts of legends about them, up to horror films.However, all this is gossip and slander. The hawk maker does not bite anyone, he is indifferent to human flesh, and he loves only flowers!

Bruises from mosquito bites


Bruises from mosquito bites appear much less frequently than blisters, swelling and redness.Each organism individually reacts to damage to the integrity of the skin, the ingress of a foreign substance. Most of the population gets off with small blisters up to 5 mm in diameter, which disappear without special treatment in 3 days. Some people get bruised after being attacked by insects.

Feeding process

The mouth apparatus of a mosquito contains 5 special needles, 4 mandibles, a proboscis for sucking blood. Each part of the mouth apparatus performs its own function. Initially, the pest bites through the skin with powerful mandibles, then uses needles.On two of them there are sharp bristles – about 50 pieces, which are usually called mosquito teeth. They help to make the wound deeper, literally tearing the skin. The rest of the needles push the epidermis apart, preventing the wound from closing.


The mosquito inserts the proboscis into the wound, injects a special enzyme that prevents blood from clotting, facilitates the feeding process. This substance is a strong allergen, therefore it causes an instant reaction of the immune system to what is happening.

Consequences of bites

Mosquito bites

In most cases, there is swelling, redness, severe itching. How much this all will be expressed depends on the individual characteristics of the organism. A normal reaction is if the size of the blister is not more than 5 mm, the edema disappears within 2 hours, the itching stops within 24 hours.

With increased itching, an increase in the extent of redness, one speaks of an allergy. To alleviate the symptoms, folk remedies, special antihistamines are used.


A strong allergic reaction to mosquitoes can be judged by an additional rash on the body, unbearable itching, a general deterioration in well-being. There may be nausea, vomiting, diarrhea, fever, decreased blood pressure, difficulty breathing. To eliminate painful symptoms, local hormonal preparations, antihistamine tablets are used.

Causes of hematomas

Bruises from a mosquito bite

Bruises after mosquito bites appear for several reasons:

  • extremely sensitive skin;
  • individual body reaction to mosquito poison;
  • susceptibility to allergies;
  • problems with blood vessels;
  • bite with rupture of a blood vessel in the “unfortunate” place, there is a bruise under the skin;
  • long-term use of antiallergic drugs.

A bruise at the site of the bite in a mild form occurs the day after an insect attack, passes on its own without special treatment, or folk remedies are used in the form of lotions from medicinal plants.

A moderate bruise after a mosquito bite is present for a long time, slight pain is felt when pressed. It is easily treatable with pharmacy remedies for insect bites – Rescuer, Bepanten, Zvezdochka balm, Fenistil gel, creams based on herbal extracts, oils.


Large bruises, painful, which are present for a long time, indicate the presence of problems in the functioning of the vascular system, a strong allergic reaction, or improper use of glucocorticosteroids, for example, Hydrocortisone ointment. After hormonal ointment, atrophy appears, thinning of the skin, discoloration – cyanosis. In this case, you should seek help from specialists.

Any hematomas should not be neglected, even if they do not cause pain.

Why does the bruise disappear at the site of the mosquito bite. People found the answer

A Reddit user showed a photo of her bruise, and viewers are already predicting a Nobel Prize for her. Still – it seems that she discovered an extraordinary way to get rid of hematomas on the skin. True, to repeat its success, you have to be ready to become someone’s dinner.

Redditor with the nickname Hearkittykitty said that she found a mosquito bite on her leg right on top of the bruise and made an amazing discovery for herself.

There was a rather large purple bruise near the girl’s knee, but the swelling disappeared right next to the mosquito bite. Around the red dot, the skin is much lighter and now has an almost normal color.

I was bitten by a mosquito right in the bruise, and it pumped out the blood from the impact site, – wrote the surprised Hearkittykitty , attaching a picture of the hematoma.

At the site of the bite, the hematoma is less pronounced

Many spectators were also surprised by what happened with a bruise.As some admitted, they had no idea about such a “healing” property of mosquito bites. True, one of the commentators added that this is a rather sad discovery for the world of medicine, because mosquito treatment will not be the most pleasant.

The author of the post finds a cure for bruises. The treatment is less comfortable than the disease. Sad day.

Other netizens tried to find out the reason why a mosquito bite so affected the hematoma.The redditors explained that the mosquito was definitely not able to pump out the clotted blood, and it was not to their liking.

Mosquitoes only affect the blood vessels, which have enough blood and pressure to drink. Bruises are not exactly a liquid pool of blood, from which you can drink, like through a straw.

Instead, some have suggested that it is all about mosquito saliva, which works as an anticoagulant – a substance that prevents blood clots and clotting.

I think the bruise around the bite has disappeared due to the anticoagulant effect of mosquito saliva on blood.

Anticoagulants can actually speed up the resorption of bruises and are even included in many hematoma ointments. Also, mosquito saliva has a short-term analgesic effect, which is why we do not immediately notice that a mosquito has stuck to us.

True, other commentators suggested that it was a common allergic reaction, due to which the clotted blood simply became less visible under the inflamed skin.Therefore, you should not assign the role of a healer to a bloodsucker.

The mosquito didn’t drain the bruise, if you think so. It just looks more invisible due to the allergic reaction arising from the bite.

Ah, that makes much more sense. The inflammation pushes blood away from the affected area.

In addition, before you let mosquitoes close to your skin, you should see them under a microscope.After such a horror for the evening, you can not download.

Another guy also invented an amazing cure, not bruises, but scars. Vitamin helped him, and you can repeat his trick too.

90,000 Dog Eye Injuries: Symptoms and Treatment

Dogs are extremely curious and love to play. Even extremely calm dogs sometimes get scratches and other injuries. This can happen while playing, making your way through bushes, or simply digging holes. Eye injuries in dogs are a common problem.

More often than other injuries, eye injuries require immediate attention to a veterinarian ophthalmologist.
As a dog owner, you should be aware of the types of dog eye injuries and what to do in different cases.

Symptoms of damage to the eyes of a dog

Some symptoms of visual impairment indicate problems with the eyes themselves, but not always it is about injuries. There are many eye diseases. Signs of malfunction can occur in one or both eyes.If your dog has vision problems caused by injury or other reason, you may see the following symptoms:

  • The dog squints or his eyelid twitches 90 100
  • The dog cannot open its eyes 90 100
  • The dog rubs his eyes on objects or paws 90 100
  • Excessive lacrimation 90 100
  • The dog blinks quickly 90 100
  • Yellow or green discharge from the eyes 90 100
  • Bloody eyes or redness of the white part (conjunctiva) of the eye 90 100
  • Redness of the mucous membrane around the eye 90 100
  • Blurred or discolored eyes 90 100
  • Photophobia, hypersensitivity to light 90 100
  • Prolonged dilatation, prolonged constriction of the pupil or other abnormal condition of the pupil 90 100
  • Asymmetrical eyes 90 100
  • Eye edema 90 100
  • Sunken eyes 90 100
  • Bleeding from the eye area 90 100

If you find one or more signs in your pet, we recommend that you contact your veterinarian ophthalmologist.

It is not recommended to try to treat dog eye diseases at home without being examined by a veterinarian!

Occasionally, eye diseases in dogs can be more severe than they appear at first glance. The disease can develop very quickly, and the damage to the eyes is usually quite painful.

Do not risk your dog’s eyesight and do not leave him in pain – contact your veterinarian!

Types of canine eye injuries

Eye damage occurs when an object comes into contact with the dog’s eye and injures it.Eye injuries occur after a fight or “quarrel” with another dog. An animal bite, a cat’s claw, or a horse’s hoof finally can easily cause eye injury.

Many things in nature can lead to eye injury: branches, insect bites, dirt are just a few of the causes of eye injuries in dogs. Dogs that stick their heads out of the window of a moving car can suffer from specks in their eyes at speed.

Chemicals sprayed near your dog can also cause eye injuries.Your dog may hit something or be injured by a sharp object (furniture corners, fence, fish hook, tools, etc.), damaging the eyes. There are many other hazards that can damage an animal’s eyes – fireworks, hot coals, and so on. Your dog can injure his eyes by scratching his head with his paws or other objects.

Eye injuries can be moderate or severe. One or both eyes may be affected. You can’t always see how severe the injury is just by looking at the dog’s eyes.

Most common eye injuries in dogs

  • Damage to the cornea of ​​the eye – cut or scratch on the surface of the eye 90 100
  • Corneal ulcers – from chemicals or debris, or secondary if the dog scratches his eyes 90 100
  • Punctures – often from teeth, canines or foreign objects 90 100
  • Rupture of the eyelid – happens when a dog pokes his eye on an object 90 100
  • Exophthalmos – loss of the dog’s eye from the orbit; most common in brachycephalics (flat-faced dogs) such as pugs and Shih Tzu 90 100

Treatment of canine eye injuries

If you think your dog has an eye injury, see your veterinarian ophthalmologist as soon as possible.

  • Do not attempt to treat eyes yourself at home unless instructed by your veterinarian 90 100
  • First aid for eye injuries may require an eye rinse or cold compress. Do this only if advised by your veterinarian!
  • Since a damaged eye is likely to hurt the dog, you need to be very careful when doing anything in the eye area. Better if someone from your family can help you 90 100
  • Use sterile saline solution to rinse the eye.Do not use contact lens solution or any medical / veterinary drug 90 100
  • Go to a location where you have good access to the dog. If the dog is not large, it will be better to place it on the table 90 100
  • Wrap a towel around the dog. One person should hold the dog with one arm around the body and the other around the head. Be careful not to put pressure on the neck area. Hold the dog’s eye open with one hand while using the other hand to direct the jet of water into the injured eye.Use a small towel to wipe off any saline solution that comes out of the eye 90 100
  • Take your dog to the veterinary ophthalmologist.

The doctor will begin by asking about the circumstances of the injury and looking for possible causes. Then he will examine the damaged eye and assess the health of the animal.

Several eye tests may be performed, such as assessing the level of lacrimation, staining the eyes to detect ulcers or wounds, and measuring intraocular pressure.Your veterinarian will advise treatment based on your diagnosis and eye condition. It can be either a simple solution in the form of special veterinary eye drops, or an operation. Some eye injuries are so severe that surgical removal of the eye (enucleation) may be required. In some cases, the eye may be saved, but the dog will remain blind.

  • If your dog has been prescribed medication, it is imperative that you follow your doctor’s orders!
  • If multiple medications are prescribed to be applied to the eye, wait at least 5 minutes between different medications 90 100
  • If you have been prescribed eye ointment and drops, use drops first 90 100
  • Do not miss or postpone another drug intake 90 100

Most dogs with eye injuries need to wear a medical collar (the infamous cone) during eye repair.

This is an important part of the treatment and should not be ignored! This collar will prevent the dog from hurting itself. The collar should be worn by the dog at all times, except when the doctor makes exceptions.

No matter how much the dog dislikes the collar, it’s still better than a lost eye!

How to prevent injury to your dog’s eyes

Accidents do happen, but there are some tips on how to minimize their likelihood:

  • Avoid fights with other dogs 90 100
  • If a dog lives with a cat, make an effort so that they live peacefully with each other 90 100
  • Walk your dog on a leash
  • Don’t let the dog stick its head out of the car window 90 100
  • Prevent the dog from accessing chemicals and do not use them near the dog 90 100

At the first sign of an injury to your dog’s eye, contact your veterinarian.Remember that visually mild trauma can actually cause serious damage to your dog’s eyesight without proper treatment!

Side effects of hirudotherapy | Useful articles on the website of the Telos Beauty clinic prof.

Dear patients, services in the direction of hirudotherapy in the clinic are temporarily not provided.

I would especially like to dwell on the side effects of hirudotherapy. There is little coverage of this issue in the available sources of information, and this generates a lot of gossip, myths and fears.Side effects and complications are not the same thing. Side effects are considered acceptable and do not pose any danger to the health of patients. The opposite is true for complications. So, there are six side effects. These are: pain with a bite, post-leech bleeding, scars at the site of bites, a prefix reaction, a decrease in blood hemoglobin and a decrease in blood pressure. Let’s take a closer look at each effect.

Bite pain

Many patients say that in life they were attacked by leeches while bathing in natural reservoirs, and then they did not feel pain.But when the procedure for setting leeches takes place, this happens very rarely. Pain is almost always felt, varying in intensity depending on the individual pain threshold. It hurts only in the first minute, while the leech cuts the skin. When blood begins to pour out of the capillaries, the leech relaxes and the pain goes away. Thicker or blood-poor skin requires more leech work, so the severity of the sensations is stronger. They can be described as pain from a mosquito bite, or, at greater intensity, as pain from a needle prick, which is slowly rotated around its axis.As practice shows, women are less sensitive to painful sensations from leeches than men. Why do leeches bite in nature painlessly, and during procedures they do not try to anesthetize their bite? The answer, obviously, lies in the peculiarities of their origin. A leech inhabiting a river or lake is forced to feed very quickly and, if possible, imperceptibly – its life depends on it. Therefore, she numbes her bite. And the leech, grown under artificial conditions, in a biofactory, was forced to eat from birth, until it was full, without being exposed to the danger of being eaten or crushed.Why would she give off painkillers? Even leeches do not like to do extra work. Therefore, all the patients of the hirudotherapist during the session feel some pain, however, very tolerable.

Scars at the site of bites

After the wound stops bleeding, a dry thrombus remains at the site of the bite and a bruise around it is about 1-2 cm in diameter. The bruise disappears after a few days, the thrombus falls off, leaving a small fossa in its place, which quickly turns into a red and then a whitish scar of about 2-3 mm.In order for the bite mark to become completely invisible on the skin, at least two months must pass, usually up to a year, depending on individual characteristics. To minimize the cosmetic defect, special treatment can be started one week after the bite. Usually, the hirudotherapist warns the patient in advance about the possible consequences and, if necessary, avoids placing leeches on unwanted areas.

Post-leech bleeding

Everyone is very interested in the answer to the question: how much blood is lost during the procedure.This question is especially acute if blood comes out in large quantities. Quite large dressings are soaked through (for example, an adult diaper in the treatment of hemorrhoids), they have to be changed several times, and this cannot be ignored. When saturated, the leech drinks, according to its original size, from 3-4 to 7-10 milliliters of blood. Since the leech cuts the skin to a depth of 1 – 1.5 mm, capillary bleeding occurs, and not pure blood comes out, but a mixture of capillary blood with intercellular fluid and lymph.Additionally, in the period from 3 hours to a day (depending on individual characteristics), the human body loses blood to the external environment during post-leech bleeding in a volume of 10 to 30 milliliters. If not one leech is used, but several, then it will be wrong to calculate the amount of blood loss by ordinary arithmetic addition, since leeches working in a group secrete less enzymes in the total amount of enzymes than leeches working separately. As soon as the fluidity of the blood and the tone of the vessels reaches the state necessary for the leech, it ceases to secrete additional saliva and simply draws on the blood.It is easier for a group of leeches to do this job than alone. Thus, overdose does not occur and blood loss is reduced. On average, after a hirudotherapy procedure, a person loses about 50 – 70 milliliters of blood. Since this process lasts many hours, the body has enough time to activate reserves and compensate for losses, and apart from autonomic vascular reactions, visible changes are usually not observed.

Prefixed reaction

The most unpleasant side effect of leech treatment is considered to be a prefix reaction.Its cause is considered to be the activation of the immune system, accompanied by the release of inflammatory mediators from the mast cell granules into the tissues. The reaction is manifested by redness, swelling and itching of the skin at the site of leech bites. Most often, complaints continue to bother especially intensely during the first two days. Then they spontaneously go away, even if no treatment has been carried out. Depending on the individual sensitivity of the skin and the activity of the immune system, this reaction can look different: from complete unresponsiveness to pronounced skin edema (up to 5-10 cm in diameter) and itching.Usually, the prefix reaction is confused with allergies, and this is where the leech treatment ends. However, everything is not so simple and scary. All of us were once bitten by mosquitoes. Their bites cause itching, swelling and redness of the skin. After a while, the symptoms disappear. They manifest themselves in different people in different ways. Someone doesn’t react in any way. Others suffer from itching for a week, scratching the bites until they bleed. In such cases, marks remain on the skin. And if a midge bites, then such a life experience is stored in memory for years, especially if the skin of the face suffers.The swelling and unbearable itching are troublesome for several days. And these phenomena are not considered allergies. Why? Because these insects bite us all our lives, and besides small scratches, there are usually no troubles. With a true allergic reaction, each new intake of antigen in the human body causes the formation of more and more antibodies, which leads to an increase in the immune response in response to each subsequent exposure. Therefore, allergies tend to progress and the severity of its symptoms usually requires emergency hospitalization.With mosquitoes, midges and leeches, the picture is completely different.

Not all people have the prefix reaction. More often elderly people and overweight people suffer. In children, the reaction is minimal or absent. On the mucous membranes, it does not exist at all, which is an additional difference between the prefix reaction and a true allergy. Usually, after the first setting of leeches in life, at least 5 – 7 days should pass before the reaction develops. After the immune response to the aggression of the leech is formed, the body’s memory for this factor remains for life, and setting one leech even after ten years will lead to itching of the skin the next day.An interesting fact, but if, despite the edema and itching, continue the course of setting leeches, the prefix reaction eventually loses its severity and disappears altogether. And after a pause in treatment for a period of 3-4 weeks, she returns. So, every patient who is going to undergo a course of treatment with leeches should be prepared for the fact that he may have to endure some discomfort associated with severe itching and redness of the skin at the site of the bites. It is important to realize that these are not symptoms of a purulent infection and not an allergy, and the experience of the first three days of treatment will prove the correctness of this statement.

Decrease in blood hemoglobin and decrease in blood pressure

Treatment with hirudotherapy for diseases such as hemorrhoids, thrombophlebitis, hydradenitis, and some others is usually accompanied by profuse bleeding and loss of a certain amount of iron by the body, which is reflected in laboratory blood tests by a decrease in hemoglobin levels and the number of red blood cells. Since this condition develops not as a result of a chronic debilitating disease, but as a result of post-leech bleeding, with adequate nutrition, the body recovers quickly.As a result of the leech’s intervention in the processes of internal regulation of vascular tone, as well as the psycho-emotional reaction to an unusual procedure and the type of blood, in some patients, more often young women, blood pressure may reflexively decrease, which is manifested by darkening in the eyes, dizziness. These symptoms disappear in a few minutes on their own and do not pose a health hazard.

In the overwhelming majority of cases, negative aspects of leech treatment arise in the absence of explanatory work by doctors – hirudotherapists among their patients, which leads to their inadequate response to safe side effects of therapy.Bleeding is usually assessed as a consequence of trauma to a large vessel, and, accordingly, requiring urgent surgical intervention. The prefix reaction can be regarded as an infectious purulent process of the subcutaneous tissue or an allergy to a leech bite.

How to recognize which insect has bitten you

Few people in life manage to avoid insect bites. In summer, this problem is especially relevant. Sometimes it is difficult to determine who bit you. The wound may hurt, itch, and edema may appear.But don’t panic.

Bright Side created a little cheat sheet so that you know exactly which insect attacked you.


Mosquito bites look like swollen redness the size of a small berry. Most often they are located in open areas of the body. Mosquitoes bite where the skin is thinnest and it is easier to reach the blood vessels. When biting, they inject saliva into the wound along with blood thinning anticoagulants. Because of them, tissue edema, redness and itching occur.


The body reacts to a tick attack with a red spot at the site of the bite. The insect can stay on the victim for a long time and grow in size, feeding on its blood.

The worst thing is that ticks infect people with encephalitis, borreliosis and many other diseases. If, after removing the insect, the round spot on the skin has not gone away, but only increased in size, see a doctor as soon as possible.


Flea bites can be confused with allergies or mosquito tricks because similar red bumps appear on the skin.But, unlike mosquitoes, these insects bite quite painfully, their bites itch much more strongly.

Fleas usually attack the legs and only a sleeping person can bite in other places. One insect can bite a person several times, so the distance between spots is often 1-2 cm. Fleas carry many diseases dangerous to humans.


A sting may remain at the site of the bee sting, which must be carefully removed. The skin usually turns red and swelling appears.A person feels acute pain and burning, and after a while, severe itching. If there is no allergy, then the troubles that will have to be experienced end there. If there is an allergy to bee venom, then a person may begin to suffocate, and then one cannot do without medical assistance.


Symptoms after a wasp attack are similar to those that occur after a bee attack. At the site of the bite, red swelling, sharp pain and burning, and then unbearable itching appear. There may be hemorrhages on the skin.A wasp can bite a person several times. As in the case of the bee, it is important that there is no allergy to insect venom, otherwise anaphylactic shock may occur.


At the site of the hornet bite, redness and severe swelling of the tissues appear, blisters may appear. A person will feel a burning pain, even more acute than with a wasp bite. Since hornets are larger than their relatives, their venom is more toxic. It contains histamine and acetylcholine.

If, after a hornet bite, a person feels cold in the limbs, his ears and lips turn blue, it becomes difficult to breathe, an urgent need to consult a doctor.


Most ants are not dangerous to humans. But, for example, red fiery can be troublesome. At the sites of his bites, pustules are formed – pustules, which then turn into scars. Ant venom contains toxins and a person may experience severe allergies or anaphylactic shock.

The bite of a more harmless red forest ant looks like a mosquito bite. A pink spot appears on the skin, which will then itch.At the time of the bite, the person will feel a burning sensation, as if boiling water had hit the skin.


Horsefly looks like a large fleshy fly. But, unlike her, it can be quite painful to bite a person and be fed with his blood. At first, at the site of the bite, you can see a small red spot more than 1 mm in diameter. Then there is swelling and itching. Horseflies carry various diseases such as tularemia and anthrax, but they attack livestock more often than humans.


If you notice small red dots, similar to mosquito bites, in areas where hair grows, on the head, neck or behind the ears, you have been bitten by head or pubic lice.If there are such points on the back, abdomen, arms and legs – these are the tricks of linen lice. The bites are located at a distance of several centimeters from each other, and at the site of the bite, you can notice a trace of a puncture of the skin.

Lice are carriers of dangerous diseases such as trench fever and typhus.


At first glance, bedbug bites look like traces of fleas, mosquitoes or allergies. On the skin, you can notice swelling, redness, and severe itching is felt.But it is possible to distinguish the “work” of bedbugs by the characteristic chains-paths on the skin. The bites are close to each other. And the bugs bite more painfully than mosquitoes. Multiple paths on the body can be found in the morning – bugs go hunting at night.

Treatment of hematoma on the leg

A hematoma is an accumulation of blood in the tissues of the human body, and its occurrence is caused by damage due to falls and impacts. In some cases, the appearance of a hematoma is not associated with physical influences, but is explained by the presence of a specific disease in a person.

In most situations (this concerns small hematomas), serious consequences do not occur, and the inflammation itself disappears after a while. However, there are often cases requiring medical advice and qualified treatment. Ignoring the bruise can lead to cysts or tissue necrosis.

Signs of a hematoma on the leg after a bruise

  • pain at the site of injury;
  • tissue redness;
  • the appearance of edema;
  • voltage, ripple in the impact area;
  • difficulty in movement at the site of injury;
  • 90,099 increase in body temperature.

Types of hematomas on the leg

There are two types of hematomas by the nature of their manifestation: subcutaneous and internal. The first occurs when the vessels are damaged, it is easy to detect, due to the bright color of the skin (from red to purple in the early days, and in yellow-green tones in the future). The second is more difficult to diagnose, since the place of its occurrence is the muscles themselves, and there are no traces on the skin.

Why is it not recommended to treat hematoma on the leg at home

In case of large accumulations of blood under the skin, remove it.There are enough videos and articles on the Internet describing this procedure at home, but it is absolutely impossible to follow such advice. Firstly, a person runs the risk of damaging the leg even more and disrupting its normal functioning, up to and including disability. Secondly, which is more likely, you can bring an infection into the body and provoke even more inflammation. Thirdly, only an experienced doctor using special devices will do it carefully, but independent attempts can permanently disfigure the skin, leave unaesthetic scars on it.

Methods for diagnosing hematoma on the leg

First of all, a specialist examines the hematoma. An x-ray may be done to determine the severity of the injury to make sure the bones are intact.

In case of damage to the knee joint, a puncture is performed – the joint is punctured to analyze the contents of the hematoma. If blood is found in the fluid, this indicates a hemorrhage into the cavity.

Treatment of hematoma on the leg

Usually, a hematoma on the leg after a bruise is treated with two methods: conservative and surgical.The first category includes: cold and warm compresses, pressure bandages, taking analgesics, applying ointment, physiotherapy manipulations.

The second group involves puncture – surgical removal of accumulated blood from the site of injury with the imposition of a suture and aseptic dressing.

Treatment of a serious hematoma on the leg must necessarily be carried out under the guidance of a doctor, this will speed up the healing process and prevent unpleasant consequences.
