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?).
