What Causes Cold Sores & What They're Telling You About Your Health

Did you know that 90 percent of the population gets at least one cold sore in a lifetime, and 40 percent of American adults repeatedly get cold sores?

They can be painful, uncomfortable and downright unattractive, beginning as a blister and eventually forming a crust.

Cold sores are commonly mistaken for canker sores, especially in children.

Canker sores, however, involve only the mucous membrane, and they’re never on the outside of the mouth. Cold sores are caused by the herpes simplex virus (HSV), an infection that may cause only a single cold sore or an outbreak of several cold sores.
