cold sores
"I have suffered with cold sores since I was in 2nd grade.  I am 38 now.  The outbreaks are generally from fall till spring, and in the past would occur one after another.  I developed horrid scarring around my mouth from them, and they even spread to my nose, my EARLOBES, and the bridge of my nose (too close to my eyes for comfort) my physician figured I spread it in my sleep. I also have eczema, which just makes it easier to spread it around.  Valacyclovir has been a miracle for me.  I try to catch at the tingle/itch, but if I wake up with one, I take immediately.  It stops them in their tracks and heals them in as little as three days."
