I have this yukky chronic problem. Anyone else know anything about it? I just found out about it last week. I also had to have a biopsy...just in case it's oral cancer and not lichen planus but I know it's unlikely. Doesn't stop me from wondering, being high strung. I can't find anyone who had experience with this. Nobody even knows about it. Anyone here have experience or know someone? You can get it anywhere, but mine is in my cheek. I thought I was biting my cheek in my sleep. Guess not.
