I was also stage 4 tonsil cancer. My first surgery was November 2, 1910 and then it recurred 6 months later. My second surgery was June 27, 2011. Had neck dissection again and flap surgery. Docs said I was "cancer free" at this point, however, I contined to have jaw pain. They discovered exposed bone about 6 weeks ago. I take pain meds every 3 - 4 hours. Just had a bone dental scan and a PET scan and am waiting for the results. Doc said that I might need jaw replacement surgery. It does not seem to be healing on its own. Not looking forward to another surgery, but also can't handle the pain. Has anyone experienced this?
