It's herpes most likely.

Well, after seeing a picture of oral herpes, they are much smaller than that. They barely raise above the skin, you can't see them without a close inspection.

Nothing to be ashamed of, have your dentist write you an oral, presc. for valtrex. As soonas you begin to feel the tingle take 2 tablets. That simple, after 12 hours take 2 more.,the blisters or sores will never develope. Wish Id known this years ago. I also like the Abreva....works super quick

There are different kinds of herpes as far as I know.
