herpes simplex
"I've had cold sores come up before but normally treating the area with ice and lemon juice stopped it from coming out but this time I didn't have the chance to do that so it ended up sprouting out. It started off small and I applied abreva but it just got bigger and bigger. I don't think that's the abreva's fault because it was bound to get bigger but I think it may be spreading because of it. It honestly doesn't do much and it also doesn't feel like anything is happening. I prefer using vanilla extract, ice, lemon juice, advil paste and cornstarch paste to help because I actually feel it working."
