I have a bump underneath the skin in the center of my lower lip.(on my face) It looks white around th edges and looks black or dark grey in the center. It is a small bump. You can really only see it when I smile or stretch my lower lip. I have never had this. At first I thought it was a blackhead, but it is too big for that and it is under the skin. It isn't a cold sore, it isn't red and doesnt hurt unless I try to sqeeze the heck out of it. It is a firm bump.
It has been there for a week. Hasn't gotten any bigger or smaller. What the heck could this be?
