No - no thryoid issues here. This definitely is a rarer location for OC -- the fact that there are only three of us on here who have had it certainly indicates that. I'm just glad I decided to see a periodontist when I did! He was the one who did the biopsy.
About the stretching exercises...Yes, it is odd that the doctors don't emphasize them more, considering how crucial they are to future health and success in so many ways. My prosthodontist was the only one to really push me on them, and I'm thankful he did.
You're almost DONE with radiation, Sharon -- yay! It'll probably get harder now before it gets easier, so hang in there for the next couple of weeks or so.
