Well I had to google what hyperbaric oxygen treatments for ORN was and it may be what I need. But I'm not sure because my ENT (or ex-ENT now) always says I'm fine. I got scared the other night because all of a sudden my swallower didn't swallow. I just came to a standstill and I freaked. I went to the emergency room and the nurses there said I need to go to my ENT and get a biopsy. I realize they're not cancer specialists, but I need to get a new ENT and have the spot they referred to checked out. It is from my first surgery last July (partial glossectomy) that has not healed yet. And now after radiation following neck dissection it is affecting my swallowing. Very unnerving.
