My wife had surgery 1 year ago and had half her tongue removed,when another tumour was found 5 months later they gave her radiation and chemo. 3 months after chemo her jaw bone started hurting and in the last three months has just gotten worse. A pet scan and mri show nothing so neither the surgeon or oncoligist can offer any reason for the pain that is in the jawbone not in the joint.Anyone have any suggestions?
