I'm just wondering if anyone else has had this happen, or knows what I can do. I get cold sores a lot, but these bumps are inside my lip now. They don't seem like canker sores to me, but I haven't had any of those in a long while. I'm not trying to have you diagnose me rather than a doctor, but I just thought I'd see if anyone else has had this happen, or what I could do if they are canker sores..?
