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?).
