I have a yellowy open group of sores on my upper lip. They do not itch, but they are painful in the way that any open wound is (sensitive to the things they touch, especially food and drink). Unlike what I might recognize as a herpes sore, they are very small and spread out in groups. When I first developed these symptoms over a year ago, they were concentrated on one side of my lip, but now I am experiencing them all over and they have lasted longer (presumably because they have opened?). They went away for months, but where they had been I could see lighter areas under the surface of my lip when I stretched it out, they resembled scar tissue and like the sores they looked like tiny dots. They seem to be going away, but I'd hate to think that this is going to continue to recur, and I certainly don't want to pass it on to anyone else!
