What Are Cold Sores?
Many people experience the unpleasant occurrence of blisters and scabs forming near their mouth. But what are they? Most of the time, these sores are caused by the Herpes virus, and they are known as cold sores or fever blisters.
Cold sores usually start out with a small tingling sensation in the location where the sore will be. The area may start to swell slightly and blisters will begin to form. These blisters usually start out as smaller liquid-filled blisters, but many times the smaller blisters form into one large blister. Eventually the blisters will begin to ooze and the sores will crust over.
