One day you look in the mirror, and you notice a sore on your lips. Is it a cancer sore, you wonder? If the blister is inside your mouth, then it’s definitely a cancer sore. But if it’s located on or around your lips, then we are talking about a fever blister. You may also know it as a cold sore.

Cold sores are quite common, and they usually are not a cause for alarm. However, the blisters are itchy, dry and painful. Besides that, no one wants to walk around with a sore around the mouth.

The question comes: How to deal with them? Well, your doctor can give you an antiviral cream. However, there are also numerous home remedies for fever blisters that you can try. First, let’s see why you have a cold sore on your lip.

What causes cold sores?

Despite the name, cold has nothing to do with cold sores. The culprit behind the fever blisters is a virus called herpes simplex. There are two types of the virus – herpes simplex 1 (HSV1) and herpes simplex 2 (HSV2).

HSV-1 is a highly contagious virus. It usually spreads through the saliva, so kissing, sharing eating utensil, towels, bathroom items like razors can get you infected. Touching a cold sore is also a bad idea.

Most often, people encounter the virus in early childhood. Someone infected with herpes kisses a child and passes the virus.

But what happens after you get the virus?

When you get infected, the virus ends in your nerves. There it lies dormant for the most part. However, certain triggers can awaken the virus. The result is a fever blister. Such triggers are:

  • Stress
  • Menstruation
  • An injury to the area
  • Deep sadness
  • Intense sunlight

Sometimes, HSV-1 can cause cold sores in the genital area. But usually, genital blisters are the result of an infection with the HSV-2. You get HSV-2 if you have oral sex with a person who has genital herpes. In some cases, HSV-2 could also be responsible for cold sores on the mouth.

Is there a way to get rid of the herpes simplex virus?

Unfortunately, there is no cure for this virus. If you have it, you’ll carry it for the rest of your life. I know that it sounds scary, but don’t worry. Up to 80% of the population has HSV-1. Most of the people don’t know that they even have it. For some of them, it might even stay dormant for years.

What are the symptoms of fever blisters?

When we talk about the symptoms of cold sores, it’s important to distinguish between first- time occurrence and recurrence.

Most people don’t experience any symptoms when they get infected with the herpes simplex virus. That’s why they realize they have it after a cold sore appears. In some cases, primary infection with herpes virus might cause the following symptoms:

  • Mouth sores and ulcers
  • Lip swelling
  • Sore throat
  • Swollen glands
  • Fever
  • Headache
  • Nausea
  • Dehydration
  • Possible swallowing difficulties

Usually, these symptoms appear in young children. In children under 5, sores might appear inside the mouth. That’s why these blisters might be confused with canker sores.

After the initial infection has occurred, in cases of recurrence look for:

  • Itching and burning. You might start to feel tingling a day before a hard and painful spot appears.
  • Filled with fluid blisters. They would appear along the border of your lips, nose or cheeks.
  • Most often, blisters emerge on the same spot as before.
  • Oozing and crusting. After the blisters burst, they would leave open sores. These sores leak fluids and then crust over.

How long do cold sores last? Well, it may take up to two weeks for the sores to heal. However, talk to your doctor if:

  • The sore is present for more than two weeks.
  • You have frequent recurrences.
  • You have a weak immune system.

How to treat fever blisters?

In most cases, cold sores clear on their own with no need for medicine. However, your doctor might prescribe your pills or cream that you can apply to the area. But, if you don’t want to bother with a visit to the doctor’s office, there is a solution.

Here’s a list of the most efficient home remedies for fever blisters. To achieve the best possible effect, use them as soon as you feel the initial tingling sensation.
