Hi Eric,
I don't bite my tongue much but I have turned my inner cheeks into hamburger more than a few times. They tell me it has nothing to do with the treatment but it wasn't that way before as I can recall. I also notice a lot of stuff in my mouth that I was oblivious too before. So far all have been normal parts of my anatomy. I still have unusual pains from muscle damage from the radiation which is a part of my "new normal".

It takes time to sort out the stuff that is normal vs. stuff that you should have genuine concern about. I relied heavily on my doctors to educate me and people on the site (like Joanna) helped a lot too. It's all part of the rite of passage of being a cancer survivor.
