Cold and Canker Sores | University Health Service

Is it a cold sore or a canker sore?

Cold sores are a cluster of blisters that first appear clear then become cloudy. First infection may be inside the mouth, but cold sores generally appear outside the mouth on the lips.

Canker sores are gray or white sores surrounded by a red inflamed area. They occur only inside the mouth, on the tongue or the insides of the cheeks, lips or throat.

What are cold sores?

Despite their name, cold sores (also known as fever blisters) are not caused by the common cold. Cold sores typically result from a viral infection called herpes simplex virus (HSV).

Cold sore blisters can occur on many different parts of the body but are most common on or around the lips, cheeks, or nose and also (on rare occasions) in the eye.

Symptoms of the initial infection are similar to those of other viral infections and may include fever, swollen glands, fatigue and multiple sores in the mouth and on the gums.

Recurrences are less severe and the individual may notice a burning or tingling sensation 24-48 hours before a cluster of blisters appear. These small fluid-filled blisters then become cloudy and pus-filled. After the blisters have broken to reveal a bright red area, they dry up, crust and heal within 7-10 days. Painful sores in or around the mouth may make eating difficult.

Symptoms subside after the initial illness runs its course, but the virus remains in the nerve cells until reactivated. Once reactivated, HSV travels down the nerve cells into the skin, causing its characteristic fever blisters typically in the same location. Most people with recurrent cold sores cannot recall having had the first infection; they may have been too young to remember or the infection may have been very mild. Some infected individuals never develop cold sores because the HSV is never reactivated; however, others may experience recurring sores several times a year.

Causes:  Herpes simplex virus (HSV) typically causes cold sores. HSV is very common. It has been estimated that nearly 50% of children entering kindergarten and 90% of adults have been infected with HSV, although a much smaller percentage has experienced symptoms.

Two types of HSV: have traditionally been differentiated by location. HSV-1 generally occurs above the waist (e.g., a cold sore on the lip). HSV-2 generally occurs below the waist (e.g., sexually transmitted sores on the genital area). However, it is possible to have a HSV-1 infection below the waist and vice versa. For example, HSV-1 infection can be transmitted from mouth to genitals during oral sexual contact. Both strains have similar signs, symptoms and course of disease, and both are contagious so contact should be avoided.

A number of factors can trigger the HSV virus, including sunlight, sunburn, stress, fatigue, other infections, fever, menstruation and intestinal upset. In many cases, the precipitating factor is unknown. Identifying triggers may allow a person to prevent recurrences by effectively removing these factors. For instance, if exposure to sunlight usually precedes cold sores by 24-48 hours, one can be fairly confident that sunlight is a “trigger” and one should minimize exposure.

Treatment: There is no cure for cold sores. However, some medications may relieve pain and soften HSV crusts on the skin. These remedies include:

  • Denavir (pencyclovir cream), a topical antiviral cream recently cleared for marketing by the FDA that may decrease the duration of lesion pain and accelerate healing.
  • Acyclovir (Zovirax) or valacyclovir (Valtrex), taken orally, may decrease symptoms if started within 24-48 hours after the onset of symptoms. With topical ointments, there is no demonstrated proof of effectiveness with recurrences.
  • A moistened styptic pencil used several times a day.
  • Zinc oxide ointment used after crusts have formed.
  • A drying agent (e.g., 70% rubbing alcohol or Blistex ointment) particularly when sores first appear.

Note: It is not recommended to use steroid ointments, dye-light therapy, smallpox vaccination or vitamin therapy (unless a deficiency exists). These techniques are ineffective and may actually make the sores worse.

Transmission and prevention:  HSV is contagious and may be transmitted by any contact with the blisters until the sore is healed. Furthermore, most people with HSV shed the virus and may be infectious even when sores are not present. Asymptomatic shedding from the site where sores appeared may occur randomly up to 3-6 days or more each year.

Therefore, people with oral HSV who are sexually active should use condoms or latex barriers with every oral sexual encounter. Spreading the cold sore to another site on your own body is not common; however, washing hands after touching any sore is reasonable precaution, and one should be especially wary of spreading the virus to the eyes.

When to seek medical care: Consult a clinician if:

  • Cold sores become infected with bacteria (draining pus)
  • Cold sores do not go away after a couple of weeks
  • You develop a temperature over 100° F
  • You experience eye irritation

What are canker sores?

Canker sores (aphthous ulcers) are painful sores inside the mouth. Canker sores are twice as common in women and usually first appear between the ages of ten and twenty although they may appear as early as age two.

Symptoms:  Although canker sores can appear anywhere on the mucous membranes of the mouth, they most frequently appear on the inner surfaces of the cheeks and lips, tongue and soft palate.

They are usually oval or round with a grayish-white eroded surface surrounded by a red inflamed area. The sores may occur singly or in groups and vary from about 1/8 inch to 1 -1/4 inch in diameter.

The sore may be painful for three or four days, but complete healing usually takes ten to fifteen days. Canker sores may recur many times each year.

Causes:   No one knows what causes canker sores. They may be caused by a virus, may be a form of allergic reaction or may result from an auto-immune condition (meaning that the body has developed an immune reaction against its own tissue). Some people have also found eating citrus fruit and other acidic foods increase the occurrence of canker sores, but this has not been scientifically proven.

Factors that may trigger these sores (without actually causing them) are injury or irritation (e.g., from dentures or sharp teeth), smoking, stress, a diet lacking in vitamin B12, folic acid or iron and the onset of menstruation for some women.

Treatment:  Nothing cures canker sores or prevents recurrence. There are, however, ways to ease discomfort during the 3-4 days when the sores are painful and also prevent infection.

To prevent discomfort, try to avoid irritation of abrasive or spicy foods and use care not to irritate the sore while brushing your teeth. A gel such as benozocaine can also be used to numb the sore and ease the pain.

Cleansing antiseptic medications may prevent infection and promote healing. These medications can be used as rinses or gargles 3-4 times a day or as directed on the label. Many antiseptic and pain-relief medications may be purchased without a prescription. A few examples are:

  • Hydrogen peroxide diluted with water to half-strength
  • One tablespoon of salt and baking soda in four ounces of water
  • Glyoxide (a non-prescription product)
  • Wet tea bags held over the area

Vitamins may help in cases where a specific deficiency exists. In a study at the National Institute of Dental Research, half of the people with iron, folic acid or vitamin B12 deficiencies responded favorably to supplementation while the other half showed no response.

If you experience canker sores very frequently, it may be helpful to get tested for allergies, because avoiding certain foods may minimize canker sores due to food allergies.

When to seek medical care:  Consult a clinician if:

  • Your canker sores are so severe that eating is difficult
  • You experience canker sores very frequently

Canker sore – Diagnosis and treatment


Tests aren’t needed to diagnose canker sores. Your doctor or dentist can identify them with a visual exam. In some cases, you may have tests to check for other health problems, especially if your canker sores are severe and ongoing.


Treatment usually isn’t necessary for minor canker sores, which tend to clear on their own in a week or two. But large, persistent or unusually painful sores often need medical care. A number of treatment options exist.

Mouth rinses

If you have several canker sores, your doctor may prescribe a mouth rinse containing the steroid dexamethasone (dek-suh-METH-uh-sown) to reduce pain and inflammation or lidocaine to reduce pain.

Topical products

Over-the-counter and prescription products (pastes, creams, gels or liquids) may help relieve pain and speed healing if applied to individual sores as soon as they appear. Some products have active ingredients, such as:

  • Benzocaine (Anbesol, Kank-A, Orabase, Zilactin-B)
  • Fluocinonide (Lidex, Vanos)
  • Hydrogen peroxide (Orajel Antiseptic Mouth Sore Rinse, Peroxyl)

There are many other topical products for canker sores, including those without active ingredients. Ask your doctor or dentist for advice on which may work best for you.

Oral medications

Oral medications may be used when canker sores are severe or do not respond to topical treatments. These may include:

  • Medications not intended specifically for canker sore treatment, such as the intestinal ulcer treatment sucralfate (Carafate) used as a coating agent and colchicine, which is normally used to treat gout.
  • Oral steroid medications when severe canker sores don’t respond to other treatments. But because of serious side effects, they’re usually a last resort.

Cautery of sores

During cautery, an instrument or chemical substance is used to burn, sear or destroy tissue.

  • Debacterol is a topical solution designed to treat canker sores and gum problems. By chemically cauterizing canker sores, this medication may reduce healing time to about a week.
  • Silver nitrate — another option for chemical cautery of canker sores — hasn’t been shown to speed healing, but it may help relieve canker sore pain.

Nutritional supplements

Your doctor may prescribe a nutritional supplement if you consume low amounts of important nutrients, such as folate (folic acid), vitamin B-6, vitamin B-12 or zinc.

Related health problems

If your canker sores relate to a more serious health problem, your doctor will treat the underlying condition.

Lifestyle and home remedies

To help relieve pain and speed healing, consider these tips:

  • Rinse your mouth. Use salt water or baking soda rinse (dissolve 1 teaspoon of baking soda in 1/2 cup warm water).
  • Dab a small amount of milk of magnesia on your canker sore a few times a day.
  • Avoid abrasive, acidic or spicy foods that can cause further irritation and pain.
  • Apply ice to your canker sores by allowing ice chips to slowly dissolve over the sores.
  • Brush your teeth gently, using a soft brush and foaming-agent-free toothpaste such as Biotene or Sensodyne ProNamel.

Preparing for your appointment

Your doctor or dentist can diagnose a canker sore based on its appearance. Here’s some information to help you get ready for your appointment.

Information to gather

Before your appointment make a list of:

  • Your symptoms, including when they first started and how they may have changed or worsened over time
  • All your medications, including over-the-counter medications, vitamins or other supplements, and their doses
  • Any other medical conditions, to see if any relate to your symptoms
  • Key personal information, including any recent changes or emotional stressors in your life
  • Questions to ask your doctor or dentist to make your visit more efficient

Here are some basic questions to ask:

  • Do I have a canker sore?
  • If so, what factors may have contributed to its development? If not, what else could it be?
  • Do I need any tests?
  • What treatment approach do you recommend, if any?
  • What self-care steps can I take to ease my symptoms?
  • Is there anything I can do to speed up healing?
  • How soon do you expect my symptoms will improve?
  • Is there anything I can do to help prevent a recurrence?

Don’t hesitate to ask any other questions during your appointment.

What to expect from your doctor or dentist

Be ready to answer questions from your doctor or dentist, such as:

  • What are your symptoms?
  • When did you first notice these symptoms?
  • How severe is your pain?
  • Have you had similar sores in the past? If so, have you noticed if anything in particular seemed to trigger them?
  • Have you been treated for similar sores in the past? If so, what treatment was most effective?
  • Have you had any recent dental work?
  • Have you recently experienced significant stress or major life changes?
  • What is your typical daily diet?
  • Have you been diagnosed with any other medical conditions?
  • What medications are you taking, including prescription and over-the-counter medications, vitamins, herbs and other supplements?
  • Do you have a family history of canker sores?


Signs, Symptoms & Causes

For Canker Sores

Canker sores may be caused by any tear in the mouth’s lining. This can be due to an uneven tooth, rough tooth brushing, dental work, a burn from a hot drink or food, etc. A lack of vitamins and minerals, emotional stress, and having a history of canker sores can trigger them. The sores usually resolve in 4 to 14 days.

  1. •Small, round, red-rimmed sores with white or gray centers are in the lining of the mouth or on the tongue, gums, or lips.

  2. •Discomfort occurs with eating and talking.

  3. •A burning or tingling feeling can be present.

For Cold Sores

Cold sores (fever blisters) are caused by the herpes simplex virus (HSV), either HSV-1 (this is most often the cause) or HSV-2 (the usual cause of genital herpes). This virus lies dormant in the body and can return. A fever, a cold, stress, cold or windy weather, and strong sun exposure are triggers for outbreaks. Cold sores are contagious, especially when the blisters rupture and weep.

  1. •A tingling feeling is on or near the lips for 2 days before one or more sores appear.

  2. •Small, red blisters filled with clear fluid rupture and weep. Scabs form.

For Thrush

Thrush is caused by a fungal infection. Often it occurs after the recent use of antibiotics or corticosteroids.

  1. •The tongue looks red. The insides of the mouth have creamy white patches. A white coating can be seen inside the mouth and the throat.

  2. •If the throat is affected, it hurts to swallow.

General Dentistry Archives – Marshall Dental

By brushing and flossing regularly, most of us think that we’re doing all we can for our oral health. But did you know that many of us have adopted bad habits that can do major damage to our teeth? What’s more, we may not even realize it. By eliminating some of the following practices, you can protect your pearly whites even more. Read on to see if you’re guilty of any of the following:

Teeth Grinding
Also known as bruxism, teeth grinding can be brought on by stress or during sleep, unnecessary wear and tear on your teeth. Wearing a mouth guard while you sleep will help. It may also be a good idea to eliminate caffeine, which is a stimulant that can cause jaw tension. During the day, when you feel yourself tensing your jaw, put your tongue in between your teeth to remind your mouth to relax.

Chewing on Ice
You may find it gratifying to chomp away at ice chips, but this mindless habit actually puts you at risk for a cracked tooth. Make it a point to suck on your ice instead of biting it, or if you don’t think you can control the habit, drink your beverages without ice altogether.

Soda and Sports Drinks
A refreshing soft drink or sports beverage is hard to pass up. But these drinks are packed with sugar which can cause tooth decay and eat away at tooth enamel. It’s not surprising that swapping out these sugary drinks for water is the better way to go.

Brushing Too Soon
You’re an oral health superstar if you remember to brush after eating, right? Yes, but don’t do it too soon. When you eat, the acid from the food weakens your tooth enamel, so if you brush right after eating, you may be doing more harm than good. Wait at least an hour before you brush to preserve the enamel on your teeth.

Tobacco products of any kind can wreak havoc on your mouth. In addition to staining your teeth, cigarettes and the like can lead to stained teeth, gum disease, tooth loss and oral cancer. Kicking the habit is a great way to not only maintain good oral health, but to positively affect your overall health, as well.

Cold Sores and Canker Sores?What Is the Difference?

Brad Rodd, DDS, professor at theUniversity of Alabama in Birmingham,estimates that 20% to 30% of peoplesuffer from recurring cold sores (orfever blisters), which are caused by theherpes simplex type 1 virus. Like itscousin the herpes simplex type 2 virus,which causes genital lesions, the virusthat causes cold sores is contagious.

“Most people come into contactwith the virus when they are children,”Dr. Rodd said. “In some cases,the virus sets up shop in a nerve ganglionin the body. While it doesn’taffect the nerve, it can exist in thenerve forever and can erupt to the surfacefrom time to time when a patienthas a cold or fever, is experiencingstress, is exposed to the sun, or whenthere’s trauma or stress to the area,such as a patient might experience ona visit to the dentist.”

When conditions are ripe, the viruscan come “marching out,” said Dr.Rodd, resulting in a painful andunsightly eruption on the skin. Lesionsfirst become visible as small, redpapules or fluid-containing vesiclesabout 1 to 3 mm in diameter. Manylesions can coalesce into a single largerlesion, and, as the sore matures, a crustforms over the vesicles that have erupted.Cold sores usually are self-limitingand generally heal without scarring in7 to 10 days. “Cold sores aren’t somuch painful as they are embarrassing,”he said.

Unfortunately, there is not muchthat patients can do to prevent thevirus, and, once contracted, the viruscannot be eradicated. “These virusesare hidden deeply in the body so thatdrugs can’t reach them, so there’s reallyno cure,” Dr. Rodd said.

The promising news, according toDr. Rodd, is that, if patients treat theoutbreak quickly enough, they canbeat the sore back before it gets too”comfortable” on the skin’s surface.”Patients should treat the area as soonas possible?the very second they feelsomething coming on,” he said.Because lesions tend to form in thesame spot, patients usually can tellwhen an eruption is about to occur,due to tingling, burning, itching, ornumbness in the area.

Dr. Rodd recommends either Abrevaor the Zilactin line of oral health careproducts, OTC products that he believescan effectively inhibit the developmentof cold sores. The active ingredientsin these products (doconasol inAbreva and benzyl alcohol in theZilactin products) suppress sensoryreceptors and offer relief from pain anditching. Anbesol, Blistex, Campho-Phenique, Carmex, Orabase, and Orajelare other products recommendedby pharmacists for treating cold sores.

Dr. Rodd cautions that highly astringentproducts containing ingredientssuch as tannic acid and zinc sulfate arenot safe or effective treatments for coldsores and should be avoided.

Pharmacists also can recommendthat patients keep the area moist as thelesion begins to form a crust. If thelesion cracks, it may be more susceptibleto secondary bacterial infection,which can delay healing. Commonskin protectants, such as petrolatumand cocoa butter, can be used to keepthe area moist.

Patients who have recurring, but notdebilitating, cold sores may want toconsider a more systemic approach.”There are a lot of medicines that cantreat symptoms, but it may be a goodidea to try to prevent cold soreepisodes,” said Tony Welder, owner ofDakota Pharmacy in Bismarck, ND.”There are many natural medicinesthat can strengthen the immune system.Many people benefit from lysineor balanced amino acids as a preventative,besides strengthening the immunesystem with essential fatty acidsand vitamin C. The treatment of coldand canker sores with probiotics orenterobiotics may seem strange, but itworks.” Many pharmacists recommendHerpecin-L, a product that containslysine, an amino acid thought tointerfere with the ability of the herpesvirus to absorb arginine (necessary forits reproduction).

Canker Sores

In addition, Welder suggests a boostto the immune system as a preventionagainst mouth sores or canker sores.Also referred to as recurrent aphthousulcers, canker sores are found exclusivelyinside the mouth. They canrange in severity from ones that occuroccasionally and are self-healing tovery large and numerous ulcers thatcan be difficult to heal.

The sores usually form on thetongue, the floor of the mouth, thesoft palate, or the inside lining of thelips and cheeks. Most lesions last 7 to14 days and heal spontaneously withoutscarring.

Whereas cold sores have a knowncause, the cause of mouth soresremains elusive. “No one knows whythey occur,” Dr. Rodd said. “We knowit’s not an infection. It’s probablysome sort of localized inflammationproblem. There are fairly complexinteractions going on at the ulcerlevel, but we really don’t know muchmore.”

“When mouth ulcers are large,numerous, and difficult to heal, theycan be debilitating for a patient,” saidDr. Rodd. “When the condition is thatserious, the patient should really bereferred to a physician, since in rarecases severe mouth ulcers can be asymptom of a bigger problem, such asCrohn’s disease or Behcet’s disease.”Pharmacists can refer patients withpersistent mouth sores to an oralpathologist. “These specialists arefound through medical centers or dentalschools,” he said.

For milder cases (occasional lesions),treatment is focused on controllingdiscomfort and protecting the soresfrom irritation from food or routineoral hygiene. “The biggest problem isthat these lesions hurt, and OTC products,while they don’t actually heal, doa good job of providing pain relief,” Dr.Rodd said.

Topical products containing benzocaine?such as Anbesol, Orabase, orZilactin-B?often are recommended.Dr. Rodd recommends a gel formulation,because a gel provides a polymermembrane over the ulcer, helping tocreate a barrier and reduce pain. Otherproducts on the market include Campho-Phenique, Carmex, Gly-Oxide,Kanka, and Tanac. Dr. Rodd cautionsthat patients with a history of hypersensitivityto benzocaine should notuse benzocaine-containing products.

Products that release nascent oxygenalso can be used to provide temporaryrelief but should not be used for morethan 7 days. Saline rinses can providesome soothing relief to the area.

If you have cold sores, you want them to go away yesterday. An unpleasant and unsightly breakout can ruin a big event or just make you feel uncomfortable. The good news is that there are several prescription and over-the-counter remedies that can help get rid of herpes.But what’s the best medicine for herpes?


  • Herpes is caused by the HSV-1 or HSV-2 virus.
  • Antiviral drugs are available that shorten the healing time of herpes and prevent future outbreaks.
  • Prescription drugs available to treat herpes include valacyclovir, acyclovir, famciclovir, and penciclovir.

Herpes, also known as fever blisters, is caused by HSV-1 (herpes simplex virus 1) or HSV-2 (herpes simplex virus 2).They usually go away on their own within two weeks. But you can take antiviral medications to shorten healing time and suppress recurring breakouts. Antiviral drugs prescribed for herpes include valacyclovir (brand name Valtrex), acyclovir (brand name Xerese or Zovirax), famciclovir (brand name Famvir), and penciclovir (brand name Denavir).

But what is the difference between them?

Valacyclovir is one of the most commonly prescribed drugs for the treatment of herpes and genital herpes. This is likely the first medicine your doctor will prescribe for a cold sore outbreak.

Oral Valacyclovir was approved by the FDA in 1995 for the treatment of herpes labialis, genital herpes and herpes zoster caused by the varicella zoster virus (VZV).

Valacyclovir is an antiviral therapy, which means it reduces the ability of herpes viruses to multiply in your body.When you take a valacyclovir tablet, it converts to the active ingredient acyclovir. Acyclovir prevents the herpes virus from multiplying, helping to control symptoms.

Oral valacyclovir works almost immediately when you start taking it, although it can take up to 10 days for herpes blisters to heal. Studies show that valacyclovir can accelerate the healing of a herpes outbreak (Spruance, 2003), reduce the rate of recurrence of herpes, and reduce the risk of passing herpes to a partner (Hollier, 2015).

Learn more about valacyclovir, including dosages, side effects and conditions it treats, in our guide to valacyclovir.


Acyclovir is an older antiviral drug that is still widely used to treat herpes, genital herpes and shingles. Discovered in the late 1970s, it was the first highly effective herpes drug used as a first-line treatment for decades.

Do penis enlargement pills really work?

Acyclovir targets herpes DNA to prevent replication. But the drug is limited by its bioavailability or by how much it is absorbed by the body (only about 20% of the dose). This is why researchers have created valacyclovir, which is absorbed more efficiently in the digestive tract. Its level of oral bioavailability is about 55 percent.

Research shows acyclovir is effective against the herpes virus – you just need to take more than valacyclovir.


Famciclovir is another antiviral drug prescribed to fight some types of herpes infections. But unlike valacyclovir and acyclovir, which are commonly prescribed for HSV-1 and HSV-2, famciclovir is commonly used to treat herpes zoster (shingles). Just as valacyclovir is an updated version of the prodrug of acyclovir – a variant that allows more of the active ingredient to be absorbed by the body – famciclovir is a prodrug of a drug called penciclovir.


Penciclovir was approved by the FDA in 1996 for the treatment of cold sores (herpes of the lips). Due to its low oral bioavailability, it is most often prescribed in the form of topical creams. Penciclovir is the active ingredient in herpes medicines Denavir, Vectavir and Fenivir.

What is the best herpes cure?

Valacyclovir or famciclovir is probably the best medicine for herpes because it is better absorbed by the body than the previous first-line treatment, acyclovir.This way, you can take a lower dosage less frequently to see results. Other than that, there hasn’t been any direct research done to determine which medication is actually the best or most effective in treating herpes.

Is it okay if your penis has slight irregularities?

Unlike over-the-counter treatments that aim to relieve symptoms, prescription antiviral drugs can actually prevent future herpes breakouts.

Home Remedies and Treatments for Herpes

Certain over-the-counter products can relieve discomfort and help herpes heal.


Docosanol (brand name Abreva) is an over-the-counter herpes ointment that can shorten healing time. At the first sign of herpes symptoms, such as tingling, apply the remedy to the affected area as directed.

Lip balm or moisturizer

Using lip balm, petroleum jelly, or SPF (sunscreen) moisturizer on the lips can improve well-being, and moisturizing wounds is an effective way to heal them.Make sure your lips are not too dry to prevent re-damage to the area when you smile, eat or drink.

Pain relieving creams

OTC creams and ointments containing lidocaine or benzocaine can relieve the pain of herpes. Orajel is a popular brand, although its counterparts (and prescription formulations) are widely available.

Cold Compress

Apply a cool, damp cloth to the affected area to soothe irritated skin and soften scabs.

OTC pain relievers

OTC drugs such as ibuprofen (brand name Advil) or acetaminophen (brand name Tylenol) can relieve the discomfort of herpes.

Herpes against ulcers

Before looking for a cure for herpes, make sure that you are not dealing with an ulcer, but this is a completely different matter.

Herpes usually presents in three stages:

  1. Tingling, burning or itching : Herpes may be preceded by itching, burning, or tingling around the lips for a day or longer.A small, painful spot (or multiple spots) will then appear, replaced by a blister or accumulation of blisters.
  2. Blisters : Small blisters filled with liquid usually appear where the lips meet the face. Herpes can also appear around the nose or on the cheeks.
  3. Ooses and crusts : Small blisters burst after a few days. Fluid leaks from open sores and then crust over them, forming scabs.

This is how sores differ from ulcers:

  • Sores are grayish sores that form on the inside of the mouth.Herpes usually appears outside the mouth, on the lips, or nearby.
  • The sores are not caused by a virus or bacteria. Experts aren’t sure what exactly causes them. Ulcers tend to appear during stress or decreased immunity, or after trauma to the tongue or the inside of the mouth.
  • Ulcers are not contagious – they are not spread to another person’s lips, mouth or genitals. But herpes is highly contagious.
  • Unlike cold sores, sores do not respond to prescription treatments (although topical prescription steroids may be helpful).Over-the-counter medications (such as lidocaine or benzocaine cream) can relieve pain.

If you are unsure if you have herpes or sores, see your doctor. They will be able to tell you at a glance and advise you on strategies to speed up healing time, reduce discomfort, and prevent transmission of infection to others.

    How to quickly cure herpes on the lip: a variety of ways

    People have been suffering from herpes on the lips for years, wanting to know how to get rid of it quickly.There are different remedies for herpes, some of which help and some that do not. Cold sores usually go away in seven to ten days without treatment, but as most people know, if a cold is left untreated after it has completely formed, the consequences can be disastrous. However, there are certain ways to quickly cure lip cold sores.

    Orange oil

    It is commonly said that citrus on the skin can irritate and damage the skin.However, most people also know that vitamin C is very beneficial for colds.

You will feel relief if you lubricate your cold lip with orange oil at least four times a day.

    Tea tree oil

    Tea tree oil has amazing healing properties.It has been used for centuries to treat scratches and abrasions. Put some oil on a cotton swab and gently dab the sore on your lip. Do this twice a day. The sore will dry up and will soon disappear.


    Ice is a natural coagulant that can be used to treat pain, bruising and swelling. For cold sores, take a napkin, wrap four ice cubes in it, and place it on the sore. After a few minutes, the swelling and pain will diminish and relief will come.Do this at least twice a day.

    Garlic has excellent antiviral properties that can help you get relief from cold sores on the lip. Take a peeled clove of garlic and apply it to the sore. The sore will gradually decrease and then disappear completely. The good thing about garlic is that it doesn’t itch.

    Vanilla extract

    Interestingly, this remedy is often found in our kitchen, but we rarely think that it can be used to treat herpes on the lip.However, it reduces the burning sensation and pain of colds. 100% vanilla extract fights infection and prevents the development of herpes simplex virus. Apply vanilla extract on colds twice a day for a week and you will quickly get rid of cold sores.

    Preparation H

    Many will not believe that this medicine not only helps with hemorrhoids, but is also one of the most effective remedies for herpes on the lips.

    Herpes, also known as herpes labiali, is caused by the non-genital herpes simplex virus type 1.People may develop cold sores on the lips or mouth Transmission of non-genital herpes simplex virus


    Herpes, also known as herpes labialis, is caused by the non-genital herpes simplex virus type 1. People may develop cold sores on the lips or mouth.

    Transmission of non-genital herpes simplex virus type 1 (HSV-1) occurs during childhood through non-sexual contact, but adults can become infected through sexual contact.HSV-1 sleeps inside skin cells and neurons under the skin until a trigger stimulates it.

    Before the onset of herpes, people may feel a burning, tingling or itching sensation on their lips. For best results, doctors recommend starting treatment as soon as the tingling sensation begins, before the herpes appears.

    In this article, we will discuss the stages of herpes and what to do if herpes develops. We will also learn how doctors treat the infection and how people can avoid herpes.

    Stages of herpes

    Herpes develops in five stages and usually lasts 9 to 12 days.

    Stage 1

    Initially, people will feel tingling, itching, or burning under the skin around the mouth or at the base of the nose. Doctors call this the prodromal stage.

    Other symptoms that may occur during this stage include:

    • malaise
    • high fever
    • tender or swollen lymph nodes

    In this first stage of herpes, people do not see blisters. People with recurrent herpes may have milder symptoms.Doctors recommend starting treatment as soon as these symptoms appear.

    Treatment for herpes can include oral or topical medications. Sometimes people use both types to treat herpes.

    Oral herpes medications include:

    • acyclovir (Zovirax)
    • famciclovir (Famvir)
    • valacyclovir (Valtrex)

    Local treatments for herpes include:

    • acyclovir (
        abbreviation) cremanol


      • penciclovir (denavir) cream

      Treatment is aimed at reducing the duration of herpes.In one study, published in Antimicrobials and Chemotherapy , researchers found that high doses and short courses of valacyclovir could shorten the duration of herpes by about 1 day.

      Taking medication at the first symptoms can prevent or block the onset of cold sores.

      Step 2

      If the person does not take any medication, a blister filled with fluid is likely to develop 1-2 days after the first symptoms appear.

      Stage 3

      The third stage, which occurs around day 4, involves the opening of the bladder and the release of fluid. Doctors call this stage ulcerative or weeping. If another person comes into contact with blister fluid, they may develop herpes as well.

      Herpes is contagious and can be painful at this stage.

      Stage 4

      Between 5 and 8 days, the herpes dries up, leaving a yellow or brown crust. The crust will flake off over time.

      At this stage, people have to take care of the scab because it can crack or break.

      5 stage

      The final stage of herpes is the healing stage.

      Several crusts may form and flake off at this stage. Each new scab will be smaller and smaller until the wound heals completely. Most often, cold sores do not leave a scar.

      Some doctors suggest that herpes can last 2 to 6 weeks.

      Causes and risk factors

      People who come into contact with another person’s herpes may be at risk of infection.However, they will have to come into contact with the liquid when the blister ruptures.

      Some people may develop recurrent herpes. According to the American Family Physician (AAP), various stimuli can awaken the hibernation virus, such as:

      • stress
      • heat
      • sun exposure
      • extreme temperatures
      • ultraviolet radiation
      • weakened immune system
      • trauma, damage

      Are they infectious “> 2–20 days after exposure.

      People may come into contact with another person’s herpes fluid through kissing or sharing utensils, drinks, cosmetics, or towels.


      Doctors suggest that treating herpes at the onset of symptoms, before the blister appears, may prevent herpes from developing.

      People with a history of herpes can usually detect the initial symptoms and know that they need to start treatment immediately.

      Some people have chronic herpes and may need preventive treatment.Taking acyclovir or valacyclovir daily can prevent herpes.

      According to the AAP, the recommended doses for each drug are:

      • acyclovir 400 milligrams (mg) twice a day
      • valacyclovir 500 mg once a day

      People with chronic herpes need regular preventive treatment. Also, doctors and dentists recommend:

      • Eating foods high in lysine, such as red meat, fish and dairy products
      • Applying sunscreen to face and lips before going outside all year round
      • Shaving with a disposable razor when cold sores appear
      • changing toothbrushes
      • avoiding stress

      People should avoid intimate contact with people who have herpes.Avoid sharing utensils, toothbrushes, towels, and razors.

      People with herpes should not touch the blister, and if they do, they should wash their hands thoroughly.


      Herpes is a common extragenital HSV-1 infection that humans can contract through sexual and non-sexual activity.

      People who start treatment when they feel tingling and itching around the lips can block the onset of cold sores.

      If herpes develops, it goes through five stages from the prodrome stage to healing.During the ulcer stage, people can transmit the virus to another person. The liquid in the blister contains a virus. People with herpes should avoid kissing and sharing utensils, towels, and drinking utensils.

      A person can get cold sores for about 2 weeks, but some doctors suggest that herpes can last up to 6 weeks. Medication can help shorten the duration of the cold sore.

      Stages of herpes

      Herpetic stomatitis , also known as Herpes labialis , is caused by herpes simplex virus type 1.People can develop cold sores on the lips or mouth.

      Herpes simplex virus type 1 (HSV-1) enters the body during childhood and hibernates inside skin cells and neurons under the skin until risk factors “wake it up”.

      Stages of herpes

      Herpes has five stages and usually lasts 9 to 12 days.

      Stage 1

      In the initial stages of herpes, the person will feel tingling, itching, or burning under the skin around the mouth or base of the nose.Doctors call this the prodrome stage.

      Other symptoms that may occur at this stage include:

      • malaise
      • fever
      • painful and enlarged lymph nodes

      There is no blister at this stage. In people with recurrent herpes, symptoms may be milder. Doctors recommend starting treatment as soon as these symptoms appear.

      Treatment for herpes can include oral or topical medications.Both types of treatment are sometimes used.

      Oral herpes medications include:

      • Acyclovir (Zovirax)
      • Famciclovir (Famvir)
      • Valacyclovir (Valtrex)

      Local treatment for herpes includes:

      • Ointment13 Acyclovir
      • (Abreva)

      • Ointment Penciclovir (Denavir)

      Treatment is aimed at reducing the duration of herpes. In one study published in the journal Antimicrobial Agents and Chemotherapy, scientists found that high doses of Valacyclovir could shorten the duration of herpes by about 1 day.Taking medications when symptoms first appear can prevent or block blistering.

      Stage 2

      If the person does not take any medication, a blister will appear about 1-2 days after the first symptoms appear.

      Stage 3

      The third stage, which occurs on the fourth day, involves opening the blister and releasing its fluid. At this stage, herpes is contagious and usually painful.

      Stage 4

      Between 5 and 8 days, the herpes dries up, forming a yellow or brown crust. The crust will eventually flake off.

      Stage 5

      The last stage of herpes is the healing stage. Scabs may form and flake off at this stage. Each new scab will get smaller and smaller until the wound heals completely. Most often, cold sores do not leave a scar.

      Herpes usually lasts 2 to 6 weeks.

      Causes and Risk Factors

      People who come into contact with another person’s herpes may be at risk of infection.However, they will have to come into contact with the liquid when the blister bursts. Some people may have recurrent herpes. Causes that can cause cold sores:

      • stress
      • fever
      • sun exposure
      • extreme temperatures
      • ultraviolet radiation
      • compromised immune system
      • trauma

      Is herpes contagious?

      When cold sores become ulcers, around the fourth day, they become contagious.If infected, herpes can develop between 2 and 20 days after exposure. People can come into contact with herpes sore fluid through kissing or sharing dishes, drinks, cosmetics, or towels.


      Doctors suggest that treating herpes before the blister appears can prevent it. People with recurring herpes can usually notice the initial symptoms and begin treatment immediately. Taking acyclovir and valacyclovir every day can prevent herpes.

      Recommended doses are:

      • Acyclovir 400 mg, twice a day
      • Valacyclovir 500 mg, once a day

      Also, doctors and dentists recommend:

      • eating foods high in lysine, such as red meat , fish and dairy products
      • Apply sunscreen to face and lips before going outdoors
      • Shaving with a disposable blade when cold sores appear
      • Replacing toothbrushes
      • Stress avoidance

      Fever blistering may cause discomfort when attending social events or working in the community. These pus-filled mini-blisters occur when the herpes simplex virus 1 enters the body through close skin-to-skin contact or by sharing facial products 3. Fever blisters usually form inside or outside the mouth, often near the lips, and may disappear … one to two weeks to heal 3. Natural treatments for blisters are available and you can dramatically reduce the appearance of blisters in just one day 3.

      Is this an emergency?

      Seek emergency help immediately if you experience severe medical symptoms.

      Salted toothpaste

      Pour in 1 tsp. Non-gel toothpaste and 1/2 tbsp. l. salt in a bowl. Stir the ingredients for two minutes until smooth.

      Dip one cotton swab in salted toothpaste and apply to fever blister 1. Be sure to cover the entire blister with the mixture. Salt has anti-inflammatory properties that minimize redness and swelling while removing purulent fluid from the blisters in fever 3. Sodium lauryl sulfate, the active ingredient in non-gel toothpastes, deprives the herpes simplex virus proteins of adequate nutrition, leading to elimination of febrile blisters.

      Let the salted toothpaste soak into the fever blister overnight for best results. 1. Repeat the treatment once a day if necessary.

      • toothpaste without gel and 1/2 tbsp.
      • Dip one cotton swab in salted toothpaste and apply to blister 1.

      Tea Time

      Soak 1 black tea bag in cool running water. Squeeze a tea bag over the sink to remove excess liquid.

      Apply a dampened tea bag directly to the fever blister. Tea contains antiviral agents such as tannic acid, which can help the body’s defense system to kill the herpes simplex virus 2.

      Let the tea bag soak on the fever blister for 15 minutes. Rinse face with cool water to remove tea residues. For best results, repeat this procedure twice a day.


      All ingredients can be purchased at your local supermarket.

      Over-the-counter medicines such as Abreva are available to treat blisters; however, they often cause unwanted side effects and take at least three days before they show signs of improvement.

      Fever Blisters cannot completely heal until a pus-like fluid is removed from the blister. Salted toothpaste will drain all of the fluid from a fever blister in one day, forming only a tiny scab. Be patient and allow the scab to heal properly.

      To speed up the healing of fever blisters, apply ice. Wrap 1 separate ice cube in a paper towel and place over the blister. Ice can slow the development of the blister and numb the skin around the blister, relieving pain instantly. Apply ice every hour for 10-15 minutes a day until the blister heals.


      Seek immediate medical attention if fever blisters get worse, swelling of the face, or do not heal within two weeks. Although fever blisters are very common and affect almost 75 percent of the world’s population, they can be a symptom of a serious illness.Refrain from using salty toothpaste if your skin is very sensitive.

      • Soak 1 black tea bag in cool running water.
      • Let the tea bag soak on the fever blister for 15 minutes.

      There is a cold from plastic windows what to do

      It blows cold from plastic windows, what to do

      By exchanging an old tree for a newfangled metal-plastic, each apartment owner hopes to reduce the heat loss of the living space.But alas, sometimes technologies fail in the face of winter frosts and they begin to pull perceptibly from the window. There may be several reasons for this.

      Contents of the article

      Why a double-glazed window passes cold

      Incorrect installation . This problem can be suspected if you “siphon” the beginning in the very first cool days after installation. To clarify the diagnosis, it is enough just to run your palm along the slopes and the window sill near the window. And then compare the temperature of those surfaces with that of a glass unit.If the latter turned out to be warmer, then the source of the problems has been found. Now it remains only to remember exactly how the installation was carried out in order to assess the prospects for self-repair.

      It is customary to install metal-plastic windows in two ways:

      1. At a depth of 1/3 of the outer edge of the wall, when from the outside there is an opportunity to make a kind of step for a quarter of a brick. This means that from the side of the street, the window frame is held by the walls of the building, and the polyurethane foam is protected from sunlight;
      2. In the center of the wall thickness, if the step cannot be made.In such a situation, the functions of the “quarter” are assigned to the outer slope, which completely hides the foam and increases its thermal insulation properties.

      In the first case, we will allow self-repair (if the warranty is invalid). To carry it out, it is enough to open the slopes from the side of the room and check the quality of the foaming. All cracks must be thoroughly blown out with polyurethane foam.

      It is also important to look under the window tide during the repair. Quite often, the need to foam the space under it is simply “forgotten”.But during the inspection, safety precautions should be observed and, at a minimum, ask your partner to insure against falling out of the window. If a void is found under the ebb, it is also carefully blown out.

      In the same case, when the window was mounted without a “quarter”, the maximum that you can do yourself is to open the slopes and make sure that they are poorly foamed. After that, you should call the masters. Self-repair in such conditions will simply be more expensive and troublesome.

      Deformation of seals is a natural result of their long-term operation without proper maintenance. This problem is revealed by visual inspection – cracks in the elastic bands indicate the need for their complete replacement. Dismantling the old seal and installing a new one does not require special skills, the work can be done independently. In the future, in order to extend the life of this element, it must be treated with silicone-based products twice a year.

      A loose sash also manifests itself as a draft.It can be eliminated by simply adjusting the fittings, which have summer and winter modes. If there is no experience in carrying out such work, it is better to call a specialist.

      Changing the tightness of the sash depending on the season is an effective way to extend the life of the seals. In summer, the rubber bands expand and require more space, which is provided by the increased gaps between the plastic frame elements.

      Pulls from the glass unit most often when single-chamber windows were installed.Subjectively, this is felt as a stream of cold air “rolling” from the windowsill into the room. To exclude other probable reasons, it is enough to touch the glass and compare its temperature with that of the slopes in the area adjacent to the window. The wall in such a situation seems to be warmer. The only way to fix the problem is to supply heated air to the window. For these purposes, a window sill with ventilation ducts along the frame is well suited. Its visor captures the flows emanating from the heater and directs them to the glass unit, thereby preventing the accumulation of cold air in the window opening.

      Manufacturing defects are usually detected almost immediately after installation. But sometimes it is found only with the onset of cold weather. Slight skewing of the frame, violation of the tightness of the glass unit, improper fixation of the fittings become noticeable when trying to adjust the window for winter mode or with a serious difference between internal and external temperatures. The problem can be eliminated only together with the defective window – for this you need to contact the company that installed it.

      Advice on use and selection

      To avoid depressurization of window frames with the onset of cold weather, it is necessary to adjust the fittings in time. In addition to controlling the “winter-summer” positions, tightening the screws will allow you to get rid of the sagging of the sashes.

      It is also important to control the direction of heat flows. If the protruding window sill and heavy curtains prevent it from entering the window opening, this will provoke the accumulation of air cooled by the glass unit, which will create the illusion of drafts.

      When choosing windows, it is important to take into account that single-chamber options are suitable only for warm regions. If in winter the temperature drops below -10 ° C, then such windows will seriously blow cold. There are several ways to avoid this

      • selection of two or multi-chamber windows;
      • Installation of double-glazed windows filled with noble gases;
      • Inner glass tinting with short-wave radiation filtering film.

      The first two methods reduce the total thermal conductivity of a plastic window.The third reduces it to a possible minimum. The fact is that the shielding layer freely transmits long-wavelength sunlight without affecting the illumination of the room. But short-wave ultraviolet does not release outside. As a result, even the glass itself feels much warmer to the touch than analogs without such a coating.

      And finally: it is advisable to control the process of installing windows. After all, it is the results of improper installation that are the most common reason that cold bridges appear in the window opening.

      BBC News – Plague of plastic windows?

      Plastic windows and doors look out of place

      English Heritage is launching a study to help protect official reserves, and one of its goals is to replace wooden-sash windows with the plague of plastic. So what about using PVC in a vintage home?

      When an adventurous real estate agent shows you a Victorian home, they often reel in a list of historical features they think will help you fall in love and they get their commission.

      You will hear “fireplace, cornices, ceiling rosettes, railings, paneled doors”, each of which is expressed in voice tones usually associated with chocolate advertising. But the subject of agent resistance is often the “original casement windows”, delivered with a verbal frill.

      Sash windows can be expensive to repair and very expensive to replace


      “Those who sell double glazing have made a big marketing ploy to point out the benefits. Many people choose the easy option to replace them. ”

      As a rule, double-glazed windows with plastic frames come to replace, which connoisseurs call with contempt the general term uPVC.

      But this, according to the English heritage, spoils the appearance of more than 9000 nature reserves in England – territories officially recognized as historically important.

      On one side, casement windows are framed with high-quality, slow-growing coniferous wood, brought from the Baltic forests in the 19th century.A sash window usually consists of two frames or sashes with anything from one to half a dozen or more glass panes. They slide in the window body while they are stabilized by sash weights attached to the cords and hidden in the window body.

      On the other hand, you have modern plastic windows that usually hinge open. These are very different beasts. Like other modifications, plastic looks out of place next to older materials.

      Hinged windows help preserve the historic look

      “We really encourage people to do their jobs with the right materials,” says Wood.”If you start changing materials, they will be completely different.”

      Of course, for many, casement windows are an expensive luxury. You can move into an old house, find that the frames or box have rotted, and get a quote from the joiner.

      “It can cost money,” says Mr. Wood. “I’ve seen the work done very cheaply and at great cost.” According to him, it is important to keep in mind that repairs are often cheaper than replacing with PVC.

      But perhaps even more serious criticism in the 21st century is the environment.

      All members of the Friends of the Earth State Fund for Energy Saving support the use of double glazed windows to prevent heat leakage from homes and therefore reduce carbon emissions. The Trust says that if everyone in the UK needed to install double glazing would get That would save £ 700 million a year, which is equivalent to the CO2 emissions of around 740,000 households.

      But environmentalists are not going to give up without a fight.Wood says there are many things that can be done to reduce heat loss as much as with double-glazed windows.

      These are probably the most photographed casement windows in England

      Cleanup first. The brush strips are attached to two frames so they fit better when closed. Rubber or silicone is available as a cheaper alternative.

      Second avenue is cheaper – close the curtains.With heavy curtains or shutters that completely cover the windows, heat loss can be the same as with open double glazing.

      The third method is to install secondary glazing, essentially a form of double glazing provided by a block on the inside of the window.

      Double glazing in a contemporary style of casement, but English Heritage believes this usually does not look appropriate.

      Those who are in nature reserves should remember not only the appearance, but also the laws.If you have casement windows and your local council has a so-called “four-way clause”, you must obtain a building permit to replace them with plastic windows. A listed building requires a building permit.

      Of course, for many homeowners, the reason for keeping windows is neither conservation nor legal, but purely financial. Who wants to strip a real estate agent of some of the drag when they try to move your home?

      Here are some of your comments.

      I completely agree with English Heritage. These plastic windows and doors of the toy town look just awful. The right wooden window or door not only looks better, but with proper care it can last indefinitely. On the other hand, PVC will last a maximum of 25 years if you’re lucky. We can say that PVC windows are more energy efficient, but what about the environmental damage caused by their production and disposal too early? Plastic can be used in toys and some household items, but not in the home.
      Jonathan Haw, Lincoln

      If PVC windows were available to the original builder, they would use them. They significantly improve the old types of windows in all respects (durability, draft protection, energy efficiency, etc.). Nobody can convince me that they would not have been installed initially if they were available.
      John, Wilts

      Typically, English Heritage and the BBC post outdated comments on PVC windows.The PVC-U industry has invested heavily over the past five years in modern windows and doors that more closely replicate old-style windows, innovations such as white imitation wood and colored foil that replicate wood frames. Composite doors with wood grain effect are widely used now. The images used to illustrate this article are outdated and show early generation PVC products that have now been replaced by much prettier windows and doors.
      John Coey, Windows Active Magazine, Rickmansworth

      I hate PVC windows, they completely ruin the look. The environmental arguments for them are also flawed; pound for pound, you’ll save more money and cut CO2 emissions by more with better roof insulation (mind the rise in temperature) and some decent curtains. Plus, PVC-U is a man-made plastic that’s wreaking havoc on the planet, while casement windows can be made from artificial forest where you actually reduce pollution (trees trap CO2 as they grow and then stored in your windows)! Plus sash windows last longer if looked after as PVC becomes terrible over time.
      David, Kent, UK

      In terms of environmental concerns, the article does not mention the significant environmental benefits of wooden windows versus plastic. Wooden windows, whether they are sash, sash or any other style, can be repaired and last longer. 100 years, while plastic windows will collapse, cannot be repaired and often have a lifespan of only 20 years.

      And when plastic windows need to be replaced, old ones often end up in landfills, where PVC-U is one of the most unpleasant and environmentally harmful substances.Although they can be recycled, it is clear that this requires more energy consumption. The best options for both our artificial and natural environments are wooden windows and heavy curtains.

      English Heritage should stop this nonsense. When closed, most windows generally look better than older alternatives and better for the environment. PVC windows will retain their appearance much longer than wooden ones and do not require painting with paint with a high solvent content.Alternative paints look like rubbish even faster and don’t protect windows properly. In general, there is nothing to recommend “traditional” wooden windows, and the sooner they are completely banned, the better.
      Tim, Steeple Essex

      English Heritage It should be remembered that an Englishman’s house is his castle and why should some guy in London decide if I can have double glazing or a shower in my house? After all, this is MY home.

      If English Heritage is to protect the heritage of old buildings, they need to understand that these buildings should be welcome, not more hassle than they are worth! It is a shame when it is easier to bring a building into decay than to adapt it to modern living conditions.
      Brian Parks, Farnborough

      This is a false dichotomy. There are (at least) two double glazed firms that supply double glazed timber sash windows. And since none of them (to my knowledge) indulge in cold calls, you can even pick them up without disturbing your conscience. Only loafers are forced to replace wood with plastic.
      Jan Kemmisch, Biggleswade

      If this is done, people will have to insert green uneven glass into the casement.My 150-year-old windows began to rot and let in a lot of heat. Now I have beautiful transparent PVC windows that do not let in heat and do not make noise. They will last as long as modern softwood windows, as modern mahogany doesn’t last as long as it did in Victorian times. If a building has no historical or artistic value, why bother if the windows are plastic?
      Charlie, Workington

      PVC-u in an old house doesn’t look right, that’s all.I am currently looking for a house and consider PVC as a minus, I take into account the costs of dismantling it and replacing it with appropriate windows, or I just don’t go and look. I’m not sure about upvc power saving either. I wonder how much energy was spent on them?
      Adam, London

      We are currently getting a quote for replacing PVC sliding windows in our Victorian home. The originals are now in such poor condition that replacement is the only option. I didn’t even think about replacing the wood as painting all parts every few years is the biggest failure.We could get similar ones that would be cheaper but look awful in an antique property, so proper sliders, but maintenance-free uPVC is the best choice for most people.
      Jan Fuller, Staines, UK

      I would be interested to know if the same applies to original lead lamps. Our 1920s home has four lead-light windows, the rest are double glazed plastic windows, and I spend time maintaining them. But I would never replace them – faux lead double glazed headlights look so cheap and tasteless compared to real ones.
      Mike Smith, Leeds

      The 100-year-old house still has the original doors, never painted inside, and all the original lacquered wood finishes (9 “skirting boards, 4” door slats), again, none of that never painted. Taking care of them is a lot of work, such as replacing broken sash cords, but well worth it. Overall, I think this adds about 20% to the value of the home. Better to take other measures (external storm windows, good wall insulation, draft-proof doors, and a gas oven with> 95% efficiency) than sacrifice such fine craftsmanship.

      Windows PC won’t turn on

      There are many possible reasons for your PC to fail to start, from simple and easily fixable to much more complex. Whatever the reason, however, it is highly likely that your files are safe. Unless something catastrophic has happened, there is no reason to worry about your data. If the worst happens and your computer can no longer function, you can still remove the hard drive or solid state drive and access it from another computer.

      With that out of the way, let’s take a look at the first steps if your computer won’t boot.

      1. Check for Power Problems

      If your computer is not receiving power, it will not start. The obvious signs of a loss of pop power are that when you start it, nothing lights up and the fans won’t start.

      • If it is a laptop, a power outage may occur due to a full discharge of the battery.So, the first thing to do is plug it in and leave it charging for a few hours. If that doesn’t work, it could mean the charger is faulty, so if you can try another charger. If the charger has a power indicator, check if it lights up when turned on.
      • If your PC is a desktop and won’t start, make sure it’s not a power outlet by plugging it into a power outlet. another socket. If that doesn’t work, your PC might have a failed power supply.In this case, you need to replace it. Before doing this, make sure it is a power supply, if possible, remove the case and check if the power button is connected correctly – a faulty button is much easier to fix than a power supply.

      You should also try replacing your PC’s CMOS (or clock) battery. This tiny battery supplies power to the motherboard so that it can store BIOS settings. It is essentially a watch battery and only costs about $ 10 to replace.If your computer is over three years old, this is the likely reason it won’t boot.

      You should also check your PC power cable by replacing it with another and trying again. After you have removed the power cable, CMOS battery and switch, and if you are comfortable using your multimeter, you should check the power supply. If it is defective, replace it.

      2. Make sure it is not a slow boot

      Make sure your computer is not just very slow.It may sound funny, but it can happen that your computer just starts up very, very slowly. So be patient and allow 15-20 minutes to see if the problem really exists. If it installs updates or has problems with auto-launching applications, it may appear that it won’t launch.


      If startup applications are causing your computer to start slowly, you can disable them. To do this, use CleanMyPC.This makes it very easy to stop autostarting applications and slow them down.

      3. Make sure your monitor or display is working.

      If you see that your computer is receiving power because the fans start or the power lights come on but nothing else happens, there are several possible problems.

      • If you have a desktop PC connected to an external monitor, the display may be defective. Make sure the monitor is plugged into a power source and is properly connected to the computer.Try unplugging it and plugging it back in. If that doesn’t work, try connecting a different monitor if possible. This way you can either determine that this is a monitor malfunction, or rule it out.
      • If you have a laptop or if you have disabled an external display, your computer may be in sleep mode and cannot wake up. To test this, turn it off completely and restart from cold. To do this, hold down the power button for 5 seconds and then press it again to start the computer.

      4. Exclude External Hardware

      If none of the above solves your problem and you have external hardware connected, one of these peripherals could be the culprit. With your computer completely shut down, turn off everything except the keyboard, mouse, and display if you are using a desktop computer. Try running it again. If it starts up successfully, turn it off and reconnect one peripheral, then restart.If everything is ok, repeat with another peripheral. Continue until it starts, then you know you have found the problem.

      5. Reset memory modules and internal components

      This step is not for the faint of heart, especially if you have a laptop. But if you know what you are doing, you can open the case and remove and then replace the memory modules, graphics card, processor, and even unplug and reconnect the power supply to make sure a bad connection is not causing the problem.If you don’t feel competent enough to do it yourself, you should ask a friend or colleague or take your computer to a repair shop and ask them to do it.

      Some More Reasons Your Computer Won’t Turn On

      If the problem is not hardware related, you should probably check for other reasons your computer won’t turn on or freeze at startup. Here are a few things to try:

      • uninstall new software that could cause system conflicts;
      • Clear corrupted caches;
      • Perform a thorough cleaning of your PC to remove hidden junk files that prevent your PC from booting.

      Fortunately, all of these tasks can be easily accomplished with CleanMyPC, an intelligent PC cleaning tool that can help you deal with any system junk, including cache and registry errors, and get rid of unnecessary programs. Regular cleaning of your computer will not only solve current problems, but also prevent your computer from malfunctioning. The

      CleanMyPC can be downloaded for free here.

      As you can see, there are many reasons why your computer may not start.None of them mean that it is defective forever, and sometimes it is very easy to fix it. So try the tips above and see if they work for you.


      How to stop cold sores in the early stages

      If you buy something from the link on this page, we can earn a small commission. How it works.

      Herpes, also known as fever blisters, are small fluid-filled sores that appear on the lips and around the mouth.They can last for a week or more, causing discomfort as well as embarrassment due to their hard appearance.

      For many years, cold sores have simply gone away on their own, causing pain in a matter of days or weeks, but there are safe and effective ways today to help stop them or shorten the time they appear on a person’s face.

      The best way to cure herpes is to get it on before you can see it. To do this, you need to have the right medicines on hand so that they can be used at the first sign of pain.

      People prone to herpes also need to know what is causing them in order to reduce the number of outbreaks. Finally, since herpes is highly contagious, it is very important to know how not to pass it on to others.

      Share on Pinterest Treating herpes as soon as it appears is recommended to minimize the outbreak.

      Although cold sores cannot be avoided all the time, people should always try to treat it as soon as possible.

      Treatment of herpes at the earliest stage can lead to a reduction in the ulcer, which heals quickly.

      Ideally, herpes can be stopped in place so that it never appears.

      The following steps can help stop cold sores early or minimize an outbreak.

      Know the first signs of herpes

      Most people with cold sores report that they feel it even before it appears on their skin. Thus, people who have them should watch out for signs that cold sores may be developing.

      Tingling, burning, or itching may be felt around the lips several hours or a day before the herpes appears.This is the best time to start treating herpes.

      Keep antiviral drugs on hand

      People who have frequent herpes sores may want to have appropriate medications on hand so they can start using them as soon as possible.

      Medicines that have been proven to be effective for herpes are called antivirals, and they work to stop the virus from multiplying. This, in turn, can stop the herpes from developing or reduce its size and healing time.

      Antiviral drugs are available by prescription only. Antiviral medications for herpes come in two different forms:

      • Topical medications (cream) applied directly to the area
      • Oral medications (tablets) taken by mouth

      Antiviral medications are well tolerated by most people. must take antiviral drugs. The benefits and risks need to be discussed with your doctor.

      People may want a prescription to be filled and ready instead of waiting for the next cold sore to appear before they ask for it. Thus, the medicine can be taken or applied immediately after the tingling sensation or other symptoms appear.

      Antiviral drugs work best when used as early as possible, before cold sores are visible.

      Get to know the pathogens of herpes

      Because of their potentially unpleasant nature, many people seek to get rid of herpes overnight.

      However, preventing herpes is a faster and safer approach than treating an outbreak. People may try to avoid the triggers that cause cold sores, primarily by preventing skin sores from developing.

      Preventing herpes can also help reduce the risk of spreading the virus to others.

      Not all cold sores are preventable, but knowing what causes them is an important step in treating herpes. Common cold triggers include:

      • Certain foods
      • Stress
      • Illness or surgery
      • Lack of sleep
      • Sun or wind exposure
      • Skin trauma
      • Hormonal changes, especially from menstruation or taking birth control pills
      • Weakened immune system

      Keeping a diary or journal can help a person figure out what causes herpes.Recording things like diet, exercise, illness, and life events can help narrow down the issues leading up to the outbreak.

      An additional benefit of knowing the triggers of herpes is the ability to take medication even more actively. Therefore, if a person knows they have been exposed to a herpes trigger, they can be especially alert for early signs and start taking medications right away if needed.

      Think about home remedies and over-the-counter products.

      Antiviral drugs should only be prescribed for those with recurrent herpes. For occasional ulcers that do not require a prescription, over-the-counter products or natural remedies to heal and improve appearance may help.

      Some steps people can take to treat herpes early include the following:

      • Docosanol (Abreva) is an over-the-counter medicine that can shorten the duration of cold sores. Like prescription drugs, it works best early on.Abreva can also be purchased online.
      • Other over-the-counter herpes treatments containing tea tree oil, menthol, and antibacterials may also be helpful in relieving pain. Various products are available for purchase online.
      • Rubbing alcohol and hydrogen peroxide can help dry out the wound and speed up healing. However, people should stop using it if it causes more pain or irritation.
      • Local or oral pain relievers available in stores can help with discomfort.They may be safe for children, but carers should consult a pediatric doctor before using them on a child.
      • Cold compresses, ice, or cold food and drinks can help soothe the affected area. They can also aid in the healing process by fighting inflammation.

      Share on Pinterest Herpes simplex virus, which causes cold sores, can be spread through kissing or sharing drinks.

      Herpes is caused by the herpes simplex virus (HSV).Although HSV can be transmitted sexually, the herpes that causes herpes is usually not transmitted.

      HSV type 1, which most commonly causes cold sores, can be spread through casual kissing, sharing utensils or drinks, and touching the face.

      Many children and infants become infected with herpes simplex virus type 1 through adults who unknowingly transmit the virus to them by kissing or touching their face.

      The American Academy of Pediatrics (AAP) states that more than half of Americans already have the virus in their bodies by the time they become adults, most of whom were exposed to the virus before the age of 5.

      Once a person becomes infected with the herpes simplex virus, he will remain for life, since the virus remains in the body and there is no cure for it.

      HSV can remain inactive for months or even years without causing any symptoms; however, certain triggers can reactivate it, leading to cold sores.

      Herpes is easily transmitted from person to person. They can spread even when someone does not have an active ulcer.

      To avoid the spread of HSV, people can do the following:

      • Do not touch, scratch, or pick on herpes.Touching them transfers the virus to the hands, allowing it to spread to fingers, eyes, and other people.
      • Wash your hands often to help prevent the virus from getting into your hands and thus spreading.
      • Avoid sharing drinks, dishes, lip products, toothpaste, towels, or anything that might touch your mouth, especially if you have an ulcer.
      • Avoid skin to skin contact with other people if you have herpes.This includes kissing, sex, and contact sports.

      Share on Pinterest Frequent hand washing is recommended to avoid the spread of the virus.

      Herpes is rarely dangerous, but in some cases it can cause serious problems.

      HSV can spread to the eye, causing corneal scarring or blindness. According to the AAP, this is known as herpes simplex virus keratitis, which is the leading cause of blindness worldwide.

      Infant herpes can be dangerous because the immune system is not yet fully developed. Babies with herpes can become seriously ill.

      Eczema herpeticum is a dangerous complication of herpes that can occur in people with eczema. If the HSV virus comes into contact with eczema on a person’s skin, it can spread throughout the body, causing permanent scarring, blindness, and sometimes organ failure or death.

      People with weakened immune systems can also get widespread herpes infection if they are exposed to herpes.It can affect vital organs such as the spinal cord and brain.

      Most people recover completely from a cold sore outbreak without treatment.

      Despite this, the herpes simplex virus never goes away or responds to treatment, which is why people who have frequent outbreaks may want to study antiviral therapy to reduce the number of outbreaks and the risk of transmitting HSV to others.

      Anyone with herpes must be careful to avoid spreading it, especially to infants, children and those with weakened immune systems.

      Almost all the plastic in the ocean comes from just 10 rivers | Environment | All topics from climate change to conservation | DW

      At the last count, there were at least 8.3 billion tonnes of plastic in the world. Many of them are thrown away and end up in our oceans. Researchers are looking for ways to collect this debris at sea using a variety of technologies, but generally agree that using less plastic, or at least trapping the debris at source, would be much better than filtering it down.

      Read: There are 8.3 billion tons of plastic in the world

      But where to start? Well, this may actually be an easier solution than one might think. It turns out that about 90 percent of all plastic that enters the oceans is washed away through just 10 rivers: the Yangtze, Indus, Yellow River, Hai, Nile, Ganges, Pearl River, Amur, Niger, and Mekong (in that order).

      These rivers have several things in common; they all pass through areas with many people, in some cases hundreds of millions of people.But more importantly, these areas lack adequate infrastructure for waste collection and recycling. There is also little public awareness that plastic waste is a problem at all, so a lot of waste is thrown into the river and disappeared downstream.

      So the problem is huge, but the good news is that there is no need to reinvent the wheel – or any disruptive technology. Simple waste collection and recycling, as is already done in other parts of the world (with varying degrees of success), can largely solve the problem.

      “Halving the amount of plastic coming from the catchments of these rivers will already be a great success,” said Christian Schmidt, hydrogeologist at the Center for Environmental Research. Helmholtz. Schmidt was the lead author of a recent study that identified 10 rivers as major pollutants.

      Well, then let’s get started!

      • Rivers of plastic

        1: Yangtze River

        The Yangtze is the longest river in Asia and the third longest river in the world.It also tops the list of river systems through which most plastic waste enters the oceans, according to a recent study. The Yangtze flows into the East China Sea near Shanghai and is critical to China’s economy and ecology. The river basin is home to 480 million people – one third of the country’s population.

      • Rivers of plastic

        2. River Indus

        Center for Environmental Research. Helmholtz found that 90 percent of the plastic that enters the oceans comes from 10 rivers.Indus ranks second on the list. One of the largest rivers in Asia, it flows through parts of India and Pakistan into the Arabian Sea, supporting millions of people. Although a lot of plastic ends up in rivers due to the lack of waste disposal infrastructure, sewage systems also contribute.

      • Rivers of plastic

        3. Yellow River

        Plastic can enter the food chain when it is ingested by fish, other marine and freshwater animals. The Yellow River, dubbed the cradle of Chinese civilization, ranks third on the list of plastic waste, but it’s not the only environmental issue it is grappling with.The pollution has made most of the river’s water undrinkable. It is believed that about 30 percent of its fish species are also extinct.

      • Rivers of plastic

        4. River Hai
