I have currently what appears to be a small cold sore on my lip. What is interesting to me is that it has been there for several months, never opened or became "*****" and is not painful whatsoever. It is approximately the size of this "O" and has not changed since it began. I have tried numerous things to dry it out, as well as using neosporin and ice. I have googled images of everything imaginable (none which look anything like what i have) and my doctor told me it isnt something I should worry about. Well that may be true but it still sits there visible and embarassing.
From what I can gather it is not a cold sore or "fever blister" so what else could it be?
