Hi, just wondering if anyone else has ever had this. I've woken up this morning and noticed a large spot just on the inside of my lip, tried to rub it off thinking it was food!, but realised it's a spot and the only way I can describe it is like a blood blister. After rubbing it there's now a slight metallic taste.
Has anyone ever woken up with something like this out of the blue before? There was nothing there before I went to bed and I haven't bitten my mouth or anything that I can think of. It gave me a bit of a shock this morning.
