I have streaks of white stuff all over my tongue, and it doesn't rub off. And I don't mean
the usual white stuff you expect to see on
. I mean
, I can kind of draw lines in it and shift it a little bit, but when I try to scrape it with my fingernails or a note card or something it stays right where it is. It's fairly thick. And on the very back of my tongue I have a series of pupil-sized bumps. Both of my doctors also say that these bumps are normal.
