I guess we were talking more about ORNJ, osteoradionecrosis of the Jaw. Thanks for the ORN info. Here is some further info on BRON I was reading, if you don't already have it. Good luck with the spine issues or at least no further progression, I hope regression, if that is even possible. I'll have to update with my my EEG, EMG, and MRI results, which I have, but waiting to speak with the doctor.
