Cold Sores

Cold sores are small, painful blisters that usually appear around the lips. They are caused by a virus and can be annoying, but they often clear up on their own.

What is a cold sore?

A cold sore is a small, fluid-filled blister that forms on or around the lips. It is caused by the herpes simplex virus, which is a common virus that many people have without even knowing it. After the first outbreak, the virus can lie dormant in the body and may reactivate later, leading to cold sores.
