Cold Sores


Known as fever blisters or oral herpes, cold sores are caused by the herpes simplex virus. Occurring around the mouth, lip and face area, cold sores are painful and can be embarrassing for those afflicted. Because of the virus’ reputation, symptoms and their origin are commonly misunderstood.

Usually mild, recurrent infections can be caused by a variety of factors. The blister-like sores are tiny, clear, and fluid-filled. There may be one, or a group of blisters and the surrounding area may be red in color. It usually takes several weeks for the infected area to heal.

However, even after herpes has completely healed, the infection remains in the body and may recur rarely or often.


There is no cure or vaccine. Topical treatments or oral anti-viral medications can be used to treat or help suppress herpes outbreaks.
