by Mehr Jan · December 15, 2020

Have you ever seen small lesions around your lips and cheeks?

They are quite a nuisance and can be irritating.

Some people even have them appear on their gums and chin.

These are called cold sores.

Everything you need to know about cold sores is covered in this post.

Let’s begin:

1.

What are Cold Sores

So what are Cold Sores?

They are quite painful. Giving a burning sensation, they itch and if they are on the face for a long time, the sores can become crusty too.

Cold sores are also known as fever blisters.

Herpes simplex virus type 1 (HSV-1) is one of the main reasons you can get it.

Sometimes they can happen because of a stubborn infection.

While there isn’t a way in which you can cure this infection or treat cold sores, you can try some steps which will reduce the frequency in which they take place and the time duration of the outbreaks.

Stages of a Cold Sore

Your small blisters will go through five stages:

Stage 1: This is when it sets in. You will feel a certain itch and tingling. It continues for a day till the first blister appears.
Stage 2: The blisters will start to show. They are fluid-filled and affect your confidence.
Stage 3: This is when the blisters become painful. They will ooze and sometimes burst too.
Stage 4: At this point, these sores completely dry out but they lead to extensive itching and cracking of skin.
Stage 5: The scab then falls off and this is a good sign. It means your cold sores are healing.

We will now talk in detail about the risk factors that are associated to this skin condition:

Cold Sore Risk Factors

Adults who develop genital herpes simplex type 1 virus are likely to face the condition again if they are subjected to certain risk factors like:

    • A complicated infection or high fever
    • A strong cold which needs medication
    • Sun exposure for long duration
    • Stress which is leading to anxiety and depression
    • Being subjected to HIV/AIDS
    • Having a weakened immune system
    • Menstruation
    • Facing severe burns
    • Eczema diagnosis
    • Chemotherapy in progress
    • Dental work is consistent

Also, if you come in close contact with someone who has a cold sore and you are sharing the same drinks, food, kissing the person or sharing other personal items. Sharing the same virus raises your chances of being infected.

Cold Sore Symptoms

do you have a cold sore

Now we will discuss in detail how these sores form on your face. Since they are created when you contract the herpes virus, the place where they form is from where the virus enters.

Anyone who is above 20 years old who is likely to get infected by the virus will have cold sores.

In case you are getting the infection for the first-time, you will experience the following:

  • You feel a burning sensation
  • There is severe pain inside your mouth
  • Getting subjected to sore throat
  • You feel strong pain when trying to swallow
  • Headaches become frequent and you need medication for relief
  • An upset stomach

Causes of Cold Sores

Cold sore can form due to certain strains of the herpes simplex virus, HSV.

HSV-1 often causes cold sores, on the other hand, HSV-2 is responsible for genital herpes.

However, either type of cold sores can spread to the face or genitals through close contact. Sharing utensils, razors, and towels can also cause HSV-1 to spread.

Moreover, cold sores are contagious while you have oozing blisters as the virus spreads easily through contact with body fluids.

But you can also have the virus even if you do not have blisters. It is important to note that many individuals do not experience any signs and symptoms of this condition.

Once you have an episode of herpes infection, the virus lies dormant in the nerve cells of your skin and can emerge as another cold sore.

Certain factors like viral infection, fever, hormonal changes, stress, fatigue, exposure to sunlight and win,d changes in the immune system or injury to the skin can trigger it.

When to see a doctor

Cold sores aren’t a major cause of concern and they usually clear up on their own.
However, in certain cases, you will need to see a doctor when things get worse.
Get an appointment when:

  • The immune system is weaker and need professional consultation
  • You are having cold sores for more than 2 weeks and they aren’t healing, in fact getting far worse
  • The symptoms have become severe and you need medical assistance
  • A frequent feeling of recurrence of cold sores
  • There is persistent irritation in the eyes

Treatment of Cold Sores

Again cold sores don’t have a cure.

There is no magic wand that will make them disappear. Having unsafe oral sex can also trigger cold sores as well as shared eating utensils.
Once the conditions have set in, a cold sore is the last step to getting it worse before it gets better.

In this case- your herpes or viral infection.

Fortunately some people who get the virus type 2 hsv-2, they won’t have drastic outbreaks.
Whereas in the cases of those who do, fear not.

Check out these certain options that will help alleviate the symptoms:

Ointments and creams

Some of the popular oral antiviral medications you will be administered are acyclovir (Zovirax), valacyclovir (Valtrex), or famciclovir (Famvir).

However you can get these drugs only on your doctor’s prescription so it’s best you have a consultation before deciding on them.

In some cases, your doctor will suggest you take them for a few days whereas where the cold sore has advanced progressively and you have complications, a regular schedule of administration will be made. You will also be advanced to meet the doctor regularly to determine the treatment progress.
