Herpes labialis

Description

Cold sores are caused by a contagious virus called herpes simplex virus (HSV). There are two types of HSV.

Type 1 usually causes oral herpes, or cold sores. Type 1 herpes virus infects more than half of the population by the time they reach their 20s.

Type 2 usually affects the genital area

Signs and Symptoms

Some people have no symptoms from the infection. Some common symptoms are:

1. Painful and unsightly cold sores

2. Cold sores outside the mouth, on or around the lips

3. Cold sores inside the mouth, they are usually on the gums or the roof of the mouth

Treatment

There is no cure for cold sores. They normally go away on their own in a few weeks. Antiviral medicines can help them heal faster.

Other medicines can help with the pain and discomfort of the sores. These include ointments that numb the blisters, soften the crusts of the sores, or dry them out. Protecting your lips from the sun with sunblock lip balm can also help.
