Causes of cold sores

Cold sores are caused by the herpes simplex virus (HSV), which can be transmitted through close contact with an infected individual. The virus enters the body through a break in the skin, often through the lips or mouth. Once inside, the virus remains dormant in nerve cells until triggered by certain factors, such as:

  • Stress
  • Fatigue
  • Illness or a weakened immune system
  • Exposure to sunlight or extreme temperatures
  • Hormonal changes

Understanding the causes of cold sores can help you take preventive measures and reduce the frequency of outbreaks.

Symptoms of cold sores

Before cold sores fully develop, you may experience a tingling or burning sensation in the area where the blisters will appear. This is known as the prodromal stage and is a sign that the virus is active. The symptoms of cold sores include:

  • Small, fluid-filled blisters on or around the lips
  • Pain or discomfort
  • Itching or tingling
  • Redness and swelling
  • Crusting and scabbing

Cold sores typically last for about a week to ten days, and they can be contagious even when they are not visible. It’s important to avoid close contact with others during an outbreak to prevent spreading the virus.

Treatments for cold sores

While cold sores cannot be cured, there are several treatments available to help alleviate symptoms and speed up the healing process:

1. Over-the-counter creams and ointments

Antiviral creams containing ingredients like acyclovir or docosanol can help reduce the duration and severity of cold sores. These creams are most effective when applied at the first sign of a cold sore.

2. Prescription antiviral medications

If your cold sores are frequent or severe, your doctor may prescribe antiviral medications in pill or cream form. These medications can help shorten the duration of outbreaks and reduce the frequency of future episodes.

3. Home remedies

Some people find relief from cold sores by using natural remedies such as ice packs, aloe vera gel, or tea tree oil. While these remedies may not be scientifically proven, they can provide temporary relief and promote healing.

4. Prevention tips

Preventing cold sores involves avoiding triggers and taking care of your overall health. Here are some tips to reduce the likelihood of outbreaks:

  • Avoid prolonged exposure to sunlight
  • Manage stress levels through relaxation techniques
  • Eat a healthy diet rich in vitamins and minerals
  • Get plenty of rest and maintain a strong immune system
  • Avoid sharing personal items like towels or utensils


Q: Can cold sores go away on their own?

A: Yes, cold sores can go away on their own without treatment. However, this can take up to two weeks, and the symptoms may be more severe and last longer compared to those treated with antiviral medications.

Q: Can I still get cold sores if I’ve never had one before?

A: Yes, anyone can get cold sores if they come into contact with the herpes simplex virus. Once infected, the virus can remain dormant in the body and reactivate periodically, causing cold sore outbreaks.

Q: Are cold sores contagious?

A: Yes, cold sores are highly contagious, especially when the blisters are present. Avoid close contact with others and refrain from sharing personal items to prevent spreading the virus.


While cold sores can be a nuisance, understanding how they go away and the various treatment options available can help you manage outbreaks effectively. By taking preventive measures and seeking appropriate treatment, you can minimize the discomfort and duration of cold sores. Remember, if you have frequent or severe outbreaks, it’s best to consult with a healthcare professional for personalized advice and treatment options.
