Ok, I admit, I did not read all of the links, but I get what I can only describe as a cols sore. I only get it when I clean shave though. And always on the same spot.
I usually carry a beard and have for a long time. If not, I will pack a van dyke. Most people call it a goatee. As long as I do, I never get cold sores. If I clean shave, within a day or two I will start getting lil bumps that itch. If I scratch and mess with them, they become sores. If I leave them alone, they are uncomfortable but go away with only a temporary red splotch.
Herpes or not?
