It's nothing like a cold sore, I've had one of those, and this isn't it. Last night I started moticing it after eating sushi last night (I don't eat meat, so I just had a vegetable roll and tempura veggies). It feels like my lips are chapped (like that same sort of burning sensation), but there are a bunch of tiny, tiny little bumps (if you notice, theyre on the left side of my upper lip, and both sides of my bottom lip.) any idea what this could be? I have no allergies that I know of, and ive been with my boyfriend for two years so an std is out of the picture. I've looked online and can't seem to really find anything.. Helppppppp
