White bump bug bite: Lyme Disease Symptoms – What Does a Lyme Disease Rash Look Like?
Lyme Disease Symptoms – What Does a Lyme Disease Rash Look Like?
Lyme disease is the most common tick-borne illness in the United States, affecting up to 300,000 people a year, according to estimates from the Centers For Disease Control and Prevention (CDC). In certain parts of the country (particularly the Northeast or upper Midwest), checking for ticks is practically a summertime rite of passage.
Experts know that Lyme disease is caused by the bacteria Borrelia burgdorferi, which is transmitted from the bite of an infected blacklegged tick (a.k.a. deer tick). But diagnosing the condition isn’t always so straightforward. Once inside your body, the bacteria can wreak havoc in a number of ways. Yes, that can include the classic bullseye-shaped rash. But many of the other symptoms of Lyme disease aren’t as well known, and they can be frustratingly vague.
That’s why it’s important to familiarize yourself with the signs and seek medical attention ASAP if you think you or a loved one may have Lyme. The disease is typically easy to treat as long as you know what to look for.
Early symptoms of Lyme disease
The first signs of Lyme can strike anywhere from 3 to 30 days after getting bitten by an infected tick, the CDC says.
A red rash
Up to 80% of people will develop a red rash (known as erythema migrans) in the days or weeks after contracting Lyme disease. It usually forms at the site of the tick bite, and the redness is basically an allergic reaction to the tick’s saliva, says Nikhil Bhayani, M.D., an infectious disease specialist at Texas Health Hurst-Euless-Bedford.
Lyme disease rashes will often be bullseye-shaped, but they can also just be a red blotch. The rash will usually expand with time and can get as big as 12 inches. It might feel warm to the touch or look a little crusty in the center where you were bitten, but it won’t be itchy or uncomfortable. While common, it’s still worth noting that some people with Lyme may never develop a rash.
Not everyone experiences a full laundry list of flu-like symptoms. But there’s a good chance you’ll notice at least a few, Dr. Bhayani says. This potentially includes:
- Muscle and joint pain
- Neck stiffness
- Swollen lymph nodes
The flu-like symptoms are a result of your immune system’s attempt to fight off the bacterial infection and help you get better, says Kalpana D. Shere-Wolfe, M.D., an infectious disease specialist the University of Maryland Medical Center Midtown Campus.
Of course, these kinds of symptoms could indicate many different illnesses. One clue that a tick bite caused them? With Lyme disease, you won’t experience the coughing or congestion that often comes with the actual flu, Dr. Shere-Wolfe says.
Later Lyme disease symptoms
After a month or so, people infected with Lyme disease may start showing additional symptoms. These can include:
Larger or additional rashes
As the Lyme disease infection spreads throughout the body, your rash might start to expand even more. You might also develop new, smaller rashes nearby. Like the early rash, these might be bullseye-shaped. But they can also just look splotchy or blob-like, according to the CDC. They might even take on a slightly bluish tint in the middle.
Exhaustion, fuzzy thinking, and other cognitive problems
Borrelia burgdorferi is one of the few bacteria that can cross the blood-brain barrier and infect the central nervous system, explains Timothy J. Sellati, Ph.D., Chief Scientific Officer for the Global Lyme Alliance. That can lead to inflammation of the brain, which can affect your central nervous system function in a few different ways.
One of those is extreme fatigue, which affects as many as 76% of people with advanced Lyme disease, according to research. Trouble concentrating, loss of coordination, and short-term memory loss are other possible problems, occurring in up to 24% of people. In extreme cases where the disease is left untreated for extended periods, you might even develop facial weakness and behavioral changes, Sellati says.
The same inflammation that causes fatigue and fuzzy thinking can also lead to headaches, which findings suggest could strike in up to 70% of people with Lyme disease.
Usually, these feel intense and more similar to a migraine than your run of the mill tension headache, Dr. Bhayani says. In addition to throbbing pain, you might also experience hypersensitivity to noise or light.
Severe pain, numbness, or tingling in your joints and muscles
Around 60% of patients will develop joint pain or even arthritis as their Lyme disease progresses, according to a Johns Hopkins University School of Medicine study. Usually, it starts in the joints closest to where you were bitten and can spread from there, especially to areas like the knees. The pain isn’t usually constant, though. Experts don’t fully understand why, but “the symptoms can wax and wane over a period of weeks or months,” Sellati says.
Over time, the disease can attack the cartilage in the joints and lead to tissue damage, says Linda Yancey, M.D., an infectious disease specialist with Memorial Hermann Katy Hospital in Katy, TX.
Like many of the other problems caused by Lyme disease, this one is also triggered by inflammation. “The damage to tissues, bone, and cartilage is caused by the production of pro-inflammatory proteins, the same protein responsible for damage caused by rheumatoid arthritis,” Sellati says.
Heart palpitations, dizziness, or shortness of breath
In addition to invading the central nervous system, Borrelia burgdorferi can make its way into heart tissue. That can cause the tissue to become inflamed, leading to heart palpitations, Sellati explains. It might feel like your heart is pounding, fluttering, or beating faster than usual.

Usually, it becomes more noticeable with vigorous exercise or stress. The problem isn’t all that common, affecting only around 11% of patients. Still, it can be serious. “If [palpitations] occur frequently, seem to get worse, or are accompanied by chest pain, fainting, severe shortness of breath, or dizziness, you should seek immediate medical attention,” Sellati says.
One thing to note: Generally, shortness of breath is most likely to strike when you’re exerting yourself, but with Lyme that isn’t always the case. “A Lyme disease patient can experience shortness of breath during normal activity that in the past might not have resulted in this response,” Sellati explains.
When to see your doctor about Lyme disease symptoms
It’s best to seek medical attention sooner rather than later. The longer Lyme disease goes untreated, the more likely you are to develop severe complications like intense joint pain, heart problems, or cognitive issues.
Lyme disease treatment: Your doctor should refer you to an infectious disease specialist, who can evaluate your symptoms and decide whether you need testing, Dr. Yancey says. If you test positive, you’ll be given antibiotics to fight the infection.
False-negatives: If your test comes back clean, but you’re convinced that Lyme disease is the culprit, ask to be retested. False negatives are common early on since it takes a few weeks for your immune system to build up antibodies to the bacteria.

Pictures, Causes, Symptoms, and Treatment
The initial contact of a bite may be painful. It’s often followed by an allergic reaction to venom deposited into your skin through the animal’s mouth or stinger. The appearance can vary.
Whether you’re in the water, on a mountain trail, or in your backyard, wildlife you encounter have ways of protecting themselves and their territory.
Insects, such as bees, ants, fleas, flies, mosquitoes, and wasps, and arachnids, such as spiders, ticks, and scorpions, may bite or sting if you get close. Most of these animals won’t bother you if you don’t bother them, but knowing what to look for is key.
Most bites and stings trigger nothing more than minor discomfort, but some encounters can be deadly, especially if you have severe allergies to the animal’s venom.
A severe allergic reaction can happen with any bug bite or sting, depending on the person. Venom allergies may cause a dangerous, severe allergic reaction in some people, resulting in swelling, generalized itching, and difficulty breathing.
Signs of an emergency
Anaphylaxis can be a life threatening emergency. If someone experiences signs of a severe allergic reaction, call 911 or your local emergency services. Anaphylaxis can cause symptoms, including rash, low pulse, and anaphylactic shock. This can be fatal if it isn’t treated immediately.

Prevention is the best medicine, so knowing how to recognize and avoid biting and stinging insects or arachnids is the best way to stay safe.
The animals you should recognize and understand depend very much on where you live or where you’re visiting. Different regions of the United States are home to many of these creatures.
The season also matters. For example, mosquitoes, stinging bees, and wasps tend to come out in full force during the summer.
The form a bite takes depends on what type of animal bit you. Take a look at the photos below to help identify which animal may have caused your bug bite.

Here are some bugs that can be more dangerous than others.
Biting insects, arachnids, and other bugs
Many bugs bite, but only a few do so intentionally. Most bites are relatively harmless, leaving just an itchy patch of skin behind. But some bites can carry disease. Deer ticks, for example, typically carry Lyme disease.
Intentional biters include:
- chigger mites
- scabies mites
- head lice
- pubic lice
- black flies
- pus caterpillars
- kissing bugs
- deer flies
Many larger insects and other bugs won’t seek you out but will bite if handled.
Some spiders have venomous fangs. Venomous spiders found in the United States include:
- brown recluse spiders
- black widow spiders
- mouse spiders
- black house spiders
Insects will sting humans only to defend against a perceived threat. Typically, a sting from a bee or stinging ant will be accompanied by a small amount of venom.
When injected into your skin, the venom causes most of the itching and pain associated with the sting. It can also cause an allergic reaction.
Common stinging insects in the United States include:
- paper wasps (hornets)
- yellow jackets
- fire ants
Scorpions have a reputation for stinging. Many species have barbed tails equipped with venom, some strong enough to kill a human.
The most venomous species of scorpion native to the United States is the Arizona bark scorpion.
The venom injected into your body from the bite or sting of an insect or arachnid will cause your immune system to respond. Often, your body’s immediate response will include redness and swelling at the bite or sting site.
Minor delayed reactions include itching and soreness.
If you’re very sensitive to an animal’s venom, bites and stings can cause a potentially fatal condition called anaphylactic shock. This can cause the throat to tighten and make breathing difficult or cause low blood pressure.
Anaphylactic shock is considered an emergency, and 911 or local emergency services should be contacted.
Some bites and stings may cause illnesses when venom contains infectious agents.
Anyone can be bitten or stung by an insect or arachnid, and bites and stings are very common. You’re at greater risk if you spend a lot of time outdoors, especially in rural or wooded locations.
Children and older adults may have more severe reactions to bites and stings.
If you’re bitten or stung, you may see or feel the animal on your skin during the attack. Some people don’t notice the animal and may not be aware of a bite or sting until one or more of the following symptoms emerge:
- redness or rash
- pain in the affected area or in the muscles
- heat on and around the site of the bite or sting
- numbness or tingling in the affected area
Symptoms of a severe reaction requiring immediate medical treatment include:
- difficulty breathing
- nausea or vomiting
- muscle spasms
- rapid heart rate
- swelling of the lips and throat
- loss of consciousness
If you feel ill or experience flu-like symptoms in the days following an insect or arachnid bite, see a doctor for tests to rule out infections or diseases you may have contracted from the animal.
While not every insect bite or sting can cause an infection or disease, some insects can transmit diseases this way.
These insects and the diseases they may transmit can include:
- Mosquitos: insect-borne diseases such as malaria, West Nile virus, dengue fever, yellow fever, and several viruses that cause encephalitis
- Fleas: bacterial infection, rarely
- Flies: insect-borne diseases
- Sand flies: leishmaniasis, a parasitic disease, though cases occur tropical and subtropical environments
- Lice: epidemic typhus, Bartonella quintana infection, and epidemic relapsing fever
- Chiggers: scrub typhus, though most cases occur in Southeast Asia, Indonesia, China, Japan, India, and northern Australia
- Ticks: tick-borne diseases such as Lyme disease, Rocky Mountain spotted fever, Colorado tick fever, tularemia, ehrlichiosis
- Kissing bugs: Chagas disease
- Deer flies: tularemia
Many people are aware they’ve been bitten or stung because they see the insect or arachnid shortly after the attack.
Although you shouldn’t further provoke an attacking insect or arachnid, try to preserve the animal if it dies following the bite or sting. Its identity may help a doctor properly diagnose your symptoms.
This is especially important for a spider bite, as some species have dangerously potent venom.
The majority of bites and stings can be treated at home, especially if your reaction is mild.
To treat a bite or sting:
- Remove the stinger if it’s lodged in your skin.
- Wash the affected area.
- Apply an ice pack to reduce pain and swelling.
Topical anti-itch creams, oral pain relievers, and antihistamines may be used to combat uncomfortable symptoms.
You may also want to consider applying a thin paste of baking soda and water to the sting to calm the itching.
Call 911 or your local emergency services number immediately if symptoms of a severe reaction are present.
First aid instructions while waiting for paramedics to arrive include:
- loosening the victim’s clothing
- laying them on their side
- performing CPR if breathing or the heartbeat stops
If you believe a spider of the black widow or brown recluse variety has bitten you, contact 911 or local emergency services immediately even if symptoms seem minor or haven’t emerged.
Scorpion bites also should be treated as an emergency, and 911 or local emergency services should be contacted, regardless of symptoms.
Most bites and stings heal by themselves after several days of mild discomfort.
Monitor the affected site for signs of infection. Contact a doctor if the wound appears to be getting worse or hasn’t healed after several weeks.
Bites and stings that cause severe reactions can be fatal if they aren’t treated immediately.
Once you’ve experienced a severe allergic reaction, a doctor will likely prescribe an epinephrine auto-injector. Epinephrine is a hormone that can prevent anaphylactic shock.
Carry the auto-injector with you at all times to reverse the reaction immediately following a bite or sting.
If you need help finding a primary care doctor, then check out our FindCare tool here.
Use caution when near nests or hives containing aggressive insects. Hire professionals who have the proper safety equipment to remove a nest or hive.
When spending time outside, take preventive measures, such as:
- wearing hats and clothing that provide full coverage
- wearing neutral colors and avoiding floral patterns
- avoiding perfume and scented lotion
- keeping food and drinks covered
- using citronella or insect repellent
- using permethrin on clothing to prevent black-legged tick bites

bites, what they look like, where they hide
Bed bugs are dangerous and tenacious insects. It is very important to order professional bed bug extermination services as soon as possible and not to delay the solution of the problem. The faster and better the treatment is carried out, the less risks for health and comfort.
How can you tell if there are bed bugs?
To find out if bed bugs are infested, you need to do a number of simple manipulations, but it is important to do this carefully and without haste:
- Check skin : Bed bug bite marks appear as redness with swelling and are most commonly located on the neck, shoulders, back, ribs and legs. Examine all family members and pets.
- Examine bed linen : blood stains from bites, black dots and dead specimens will definitely indicate the presence of a parasite and the need for treatment.
- Sniff : bugs, with rare exceptions, exude an unpleasant odor similar to the smell of cilantro, coriander, spoiled fruits and berries, bad cognac. It will not be strong, but it can be felt next to pest clusters.
- Ask your neighbors : bedbugs rarely start in only one apartment, it is highly likely that neighbors have similar problems.
Where do bed bugs come from
It is commonly believed that bed bugs appear due to dirt, uncleanliness and the accumulation of old and dirty things, but this is not entirely true. The most common reason for the appearance of parasites in the house will be their migration from really dirty rooms: basements, from infected apartments, both from neighbors and animal hair brought on clothes.
One contaminated room can be a source of problems for countless people. And not always the presence of bedbugs in you indicates that you are doing the housework incorrectly.
What do bed bugs look like? Well-fed bugs acquire volume and become darker, almost black, while hungry bugs become flat, brown or red. Outwardly, bugs can resemble an apple seed if they are full or a rusty coin if they are still hungry.
The body of an insect consists of three conditional parts:
- Head . On it are two bulging eyes, antennae and proboscis.
- Chest . Three pairs of legs and a pair of miniature elytra are attached to it, despite the fact that the bugs do not have wings and cannot fly.
- Abdomen . Consists of 10 segments and contains odorous glands, spiracles, reproductive and digestive systems.
The size of an adult bed bug is 4 to 8 mm. The body of an insect is capable of almost doubling after saturation, which justifies the difference in average size. The larvae barely reach 1 mm after hatching from the egg and grow rapidly. The size of the egg laid by the female bed bug is about 1 mm, one individual hatches from one egg.
Males and females
The number of males and females in populations is approximately the same, but there are differences in appearance. Females are slightly larger than males and have a much more rounded body in the back. Whereas males are slightly smaller than females, and their body is pointed towards the end.
Eggs and larvae
Bed bug eggs look like small grains of rice. In some cases, they have small dents along the long side. The size is about 1 mm. The color is white, sometimes with a pearly sheen. On one side they have a hole through which the insect subsequently hatches.
With the help of a secret, they are perfectly attached to vertical surfaces. The egg also contains a special component, which, coupled with a strong shell, makes the larva almost invulnerable to mechanical damage, poisons and temperature. That is why it is very important to process the masonry with a specialized composition and with special care.
Recently hatched individuals are much lighter than adults – they are light, almost yellow. Their size increases by 1 mm after each meal – 1 time in 1-2 weeks. Then the shedding occurs. The discarded chitin remains in the nests; it is not transferred anywhere by insects and is not used.
Differences from other species
Domestic bed bugs, in comparison with others, are quite small (from 4 to 8 mm) and not so diverse in their coloration (adults – from brown to black, young ones – from yellow to light brown). They are easier to confuse with a small cockroach than with a wild relative.
Bed bug bites
What they look like
Bed bug bites look like small redness with swelling and swelling, with a pronounced center – a bump. Arranged “paths” – one after the other. Most often on the human body, bites can be found on the neck, shoulders, back, ribs and legs. Animal bodies are best examined in their entirety.
The insect spreads its proboscis, which is usually pressed against the abdomen, and punctures the skin with piercing bristles. During the bite, the insect injects the victim with a substance that temporarily numbs the area of the bite so as not to be detected. In the process of feeding, the bug moves along the body and makes 5-7 bites every 3-5 cm, each time sucking out an insignificant part of the blood. The duration of one feeding of the bug is from 3 to 10 minutes, if nothing disturbs it.
Do bedbugs bite?
No. The bug “takes care” of itself and its victim by injecting an anesthetic compound during the bite.
How fast do they go?
Usually the bites of these insects disappear within 5-7 days. If irritation and swelling does not go away for a longer time, there is a danger of an allergy and you should seek medical help.
Why bites are dangerous
Usually, for adults, bed bug bites are more dangerous from an aesthetic and psychological point of view, if there is no predisposition to allergies. Despite the fact that bedbugs are carriers of diseases, they cannot transmit them during a bite.
Biting irritation in adults can contribute to insomnia and irritability, but nothing more.
A feature of the harmful effects of bedbug bites on newborns and young children is the possibility of developing anemia, in addition to the problems that bites cause in adults.
Allergy to bedbug bites can be life-threatening for the bitten. If you have even the slightest suspicion of developing an allergy to the resulting bite or are predisposed to it, seek medical help immediately.
Signs of allergy to bed bug bites:
- Bite spot more than 1 cm in diameter
- Trail lasts more than seven days
- Rash develops
- Itching and irritation became unbearable
Treatment of bed bug bites
Bites can be treated with folk remedies, as well as with the help of medicines purchased at a pharmacy. All of them will be aimed at reducing itching, swelling and restoring the skin.
- Rescuer balm
- Gektor Gel
- Psilo Balm
- Erythromycin ointment
- Ice application
- Rubbing with rubbing alcohol
- Attaching a cut half of an onion
- Lotions from decoction of chamomile and St. John’s wort, crushed fresh mint leaves
Please note that folk remedies are a great way to temporarily solve the problem if medicines are out of reach, but they are not able to replace them.
Life cycle of bed bugs
The process of development and life span of a bed bug consists of three stages:
- Egg – 4-5 days
- Larva – up to 30-35 days
- Adult insect – up to 400 days
In the absence of food and the ambient temperature drops below +5°C, adults are able to fall into a state of suspended animation and live without food for up to 1 year or more. At an ambient temperature of more than + 50 ° C, adults, larvae and eggs die. Under adverse conditions, the development process can slow down and be up to 100 days before becoming an adult. This provides the insects with their extreme survivability.
Bed bugs reproduce in the adult stage. A female is capable of laying up to 5 eggs per day; for the entire life cycle, one female lays from 250 to 500 eggs.
Where can bed bugs hide?
