So about 4 months ago I started to get a cold sore. I did a really good job of managing it and it never fully formed. So it never scabbed over or anything like that. But instead, its almost as if it froze in the first stages where it kind of bubbles up. I don't know how else to describe it. The "bubbles" aren't colored or anything, so I don't think its contagious right now, but it is often itchy and burning. Does anybody have an idea what this is? Is this common? Is it a cold sore scar? I've seen two doctors and they have just said its not a cold sore right now.
