What is the average time a fever blister can last?

Fever blisters, also known as cold sores, can last anywhere from 10 to 14 day. Fever blisters can occur in large groups, causing red, swollen and painful wounds. They are more common near the mouth, on the cheeks and on other parts of the face. But they can also be found on the tongue or gums.

Fever blisters might release a clear fluid which scabs in a few days. Fever blisters can be contagious during this period. The virus that causes fever blisters may still be contagious even though there are no visible blisters.

The herpes virus is responsible for fever blisters. If you’re having an outbreak, know that it’s very commonplace. More than 90% of adults in the world have either one or both of these viruses (HSV-1 or HSV-2). About 65 percent of Americans have been exposed to HSV-1.

Fever blisters can be treated without need, but there are effective ways to relieve pain and promote healing. This includes both home remedies and prescription drugs.

Research has shown that essential oils can have antiviral action against HSV-1. It is possible for essential oils and other topical treatments to irritate the skin. You should test this first.

You’ll also need to dilute essential oils with a carrier oil (vegetable or nut oil). It is approximately one drop per teaspoon of carrier oils. These essential oils can be applied using a cotton pad or swab. This will help to avoid reinfection and contamination.

Here are nine natural remedies for fever blisters at home:

1. Ice

The effects of ice can reduce inflammation by decreasing blood flow. It also numbs the area so that there’s less pain. This treatment is temporary, and does not alter the virus or promote healing.

How to use Wrap an ice pack in a towel or a cloth to treat a sore. You should leave it on the cold sore at least for 5 minutes, and not more than 15 minutes. Do not apply ice directly on the skin. It can cause serious injury.

2. Lemon balm (Melissa officinalis)

A 2012 study showed that Melissa officinalisIn some cases, the herpes virus could be killed and the virus’ attachment to host cells may be affected.

How to use Use a cream, ointment or lotion to treat the problem. You can apply lemon balm, a lip balm with lemon balm, to the affected area multiple times per day. A cotton ball containing diluted essential oils may be placed on the affected area and left on it for a few seconds. Lemon balm can be used for several more days once your sores are healed.

3. L-lysine

L-lysine may be an amino acid that can help reduce the severity of fever blisters. This supplement is used as both a treatment and preventative.

Harvard Health Publications states that lysine can prevent the growth of fever blisters by inhibiting the amino acid. More research is needed to verify its effectiveness. It could also help to prevent fever blister outbreaks.

How to use Research doses can range from 500 to 3,000 mg (mg). Follow the instructions on the package.

Zinc is an important mineral that aids in wound healing. Zinc creams can be applied topically to help with fever blisters. A 2001 study showed that cold sores were less severe when a cream with zinc oxide and glycine was used than a placebo. A newer study found that zinc oxide might also play a role in the prevention of the herpes virus from entering cells.

How to use Participants who took zinc sulfate tablets in 2005 saw a decrease in outbreaks. For two months, they took 22.5 mg twice daily, and then skipped six months. Then, they took it twice daily for two more months. For topical treatments, you’ll want to apply a zinc oxide cream four times a day.

Oregano oil has been shown to block different viruses in cells, including herpes, from both animals and humans. It’s unclear what dose is needed to provide benefits.

How to use Use diluted Use oregano oil on a cotton ball to apply to the area. Keep repeating this process throughout the day until you have completely healed your blisters.

6. Licorice extract

Cold sores are being treated with licorice root. A 2014 cell study found more evidence of licorice’s antiherpetic activity, but its effects on the virus in humans still need more research.

How to use A diluted extract of licorice can be used, such as the one shown here Nature’s Answer, on your fever blister with a cotton swab or finger tips. If you’re using pills, make it into a paste with coconut or almond oil and apply to the affected area. Before you try to take licorice root orally it is important to consult your doctor.

7. Tea tree oil

An analysis of the studies on tea tree oil suggests that it could be an effective antiviral treatment. It may speed up healing time and limit the formation of plaque.

How to use Apply topically with diluted tea tree oil and a cotton ball. Apply it to the affected area several times daily. Continue treatment until your skin is fully healed.

A 1996 study showed that witch hazel was effective in fighting herpes virus infection and in relieving inflammation. Witch hazel may also act as an astringent, drying out the affected area. This could aid with healing.

How to use Use witch hazel (such Thayers Organic). Apply directly to the skin with a moistened, cotton ball. Apply light pressure to the skin and do not rub. Continue the treatment until your skin has completely healed.

9. Apple cider vinegar

Some people report benefits using apple cider vinegar (ACV) for fever blisters. While there’s no evidence for ACV and herpes, research shows that ACV may have anti-infective and antifungal properties.

Due to its acidic nature and potential tissue damage, you should use it sparingly on any wounds. It’s not recommended for bacterial infections of the skin.

How to use Apply the cotton ball with a cotton ball Apply diluted ACV to affected areas several times daily. It is possible to keep it there for several minutes. Continue treatment until healed.

It is not recommended to consume large amounts of ACV as it can cause skin irritation.

Warnings and Risks

The above remedies may not be safe for you to use if you’re pregnant or nursing. Do not use essential oils on children, or for older people. Learn how to treat cold sores among babies.

Start with a small amount of the remedy you choose to test your skin. If your skin is sensitive or it causes a burning sensation, discontinue using it. If your skin is becoming more severe, discontinue home treatments.

If you are considering taking oral supplements, talk to your doctor. Supplements and herbal remedies can interact with medications and lead to unintended side effects.

A fever blister can persist for up to two weeks if it is not treated. A fixed dose of antiviral medication is better than natural remedies. It can speed up healing and reduce the number of viruses.

This table compares the effectiveness of these medications to none treatment.

These medications are usually given as pills. In severe cases of life-threatening herpes, patients will need hospitalization. These medications will be given via vein (IV).

Research shows that all approved antiviral medications, including valacyclovir, penciclovir, and acyclovir are effective in reducing symptoms for up to seven days. Penciclovir is a topical antiviral treatment that is less effective.

Herpes simplex virus (HSV-1), also known as cold sores and oral herpes, causes fever blisters. The virus can also infect the genitals.

Symptoms don’t always appear right away. You may also have the virus lying dormant and it can recur anytime. An outbreak is generally caused by a stressed immune system.

Triggers

Some triggers can reactivate the virus, causing an outbreak. These triggers are:

  • Fatigue
  • Depression
  • Stress can be physical or emotional
  • Injury or trauma
  • Dentist procedures
  • Hormone fluctuations
  • extensive sun exposure

Another health condition that can trigger an outbreak are:

  • Infection or illness of the whole body
  • Older age
  • Individuals who have had organ transplants
  • pregnancy

An immune disorder or poor nutrition could cause a fever blister outbreak. You may also experience fever blisters if you have other health conditions.

These conditions increase the risk of developing fever blisters.

  • A weaker immune system
  • Autoimmune disease
  • Cancer
  • HIV
  • Severe burns
  • eczema

The virus can also infect the eyes, brain, and hands in more severe cases. If you notice blisters on other parts of your body, it’s crucial for you to visit a doctor. Similar infections, such as shingles, can appear and require a different treatment.

Schedule an appointment with your doctor if your fever blisters don’t show signs of healing after six days. If you have any of the following symptoms, it is a good idea to visit your doctor:

  • Extreme pain
  • You may have blisters around your eyes
  • Problems swallowing and eating
  • A weak immune system
  • frequent outbreaks
  • A severe epidemic
  • Fever
  • pregnancy
  • Drainage or reddensification that causes more severe symptoms

Your doctor may also be able help identify the triggers and root causes of the outbreaks. You can also be assessed by your doctor if other complications are possible.

Although symptoms may subside after a few weeks, the skin will need to heal completely. Normal fever blister episodes heal in two weeks. There are steps you can take during this period.

Once you have an outbreak, it’s possible for fever blisters to return. The first outbreak is usually the worst. Fever, sore throat, swelling of lymph nodes and body aches can all be symptoms of a first outbreak. Future outbreaks are less severe.

There is currently no vaccine or drug for HSV-1 and HSV-2. However, there are ways you can help reduce the frequency and duration of outbreaks. A lower chance of an outbreak is the more healthy you are.

A healthy diet can support your immune system and help you prevent outbreaks. A healthy diet is low-in sugar, alcohol, sweetened beverages, salt, and red beef. It’s high in fresh fruits and vegetables, whole grains, fiber, nuts and beans, and lean proteins like fish, chicken, and soy.
