First of all congratulations on your five year anniversary.

I'm a bit confused as you said that you are scheduled for a biopsy on Friday, yet you don't mention having been checked by a dentist or physician. I assume that it was looked at as I would be surprised that anyone would schedule a biopsy without first examining you.

That being said, from your description, it wouldn't surprise me that what you are seeing and feeling are "circumvalate papilae" which are bilateral bumps that occur on the top of the tongue. However, I could never tell you that for sure over the internet, and I would hope that whoever has looked at them or will look at them, will find that that is what they are.

Please let us know what you find out and again I am curious if someone has looked at you already.
