I get a sore patch on the side of my tongue. It comes and goes, and now I think about it, has done for well over a year now.
It's usually just a white patch, and a bit sore for a couple of days then goes away.
Anyway, it's back, it's bigger (about 5p piece size) and bloody hurts.
Do I go to the doctor or the dentist about it?
I smoke and drink if that's relevant.
(I know it's relevant, am quietly shitting myself)
