I've got a blister-like spot that keeps recurring every two weeks or so. It is just inside my mouth, near the edge where my lip meets the moist part, but is actually on the moist part iyswim. It has a tiny dot of black at the centre of it and it itches like nothing on earth. I actually keep scratching at it with my teeth and every so often it bursts and releases a thick, clear liquid
- sorry if tmi.
Anyone got any ideas? Saw dentist a couple of months ago and it wasn't as bad - apparently he couldn't see anything....
