I am 21 years old and I have a cold sore right under my nose. This is not the first time there is a cold sore outbreak. But I want to know what I can do to make it go away as fast as possible.

A cold sore looks like a blister, and it usually lasts for seven to 10 days, at which time it?s contagious. Over time, it breaks and oozes, then develop a yellow scab, with new skin growing underneath. Although a cold sore infection is generally not serious, it can be a major issue for people with depressed immune systems due to disorders or medications. Even after a cold sore crusts over and heals, the herpes virus remains, and it can cause future outbreaks in the same area of the mouth or face.
