I had cancer of the left lower jaw gum and neck almost two years years. I had a 12 hour surgery where they took part of my left tibia and muscle and rebuilt my jaw and put titanium and screws to hold it in place. I am still having pain in the left jaw. They have tried botex shots and cortizone which gave me no relief. They have me on methadone swish and magic mouth swish. Today I had a cat-scan with contrast dye. It has only been 3 months since my last scan and I am concernd. I have also ben on 10 mg of vicoden and neurotin for the pain. Could this be some kind of nerve pain because nothing really is giving me mush relief?
