Try Massage therapy. Find a good neuromuscular therapist in your area who does anterior neck and TMJ work. First develop some trust with them for a few sessions, focusing on your neck area( this alone will help TMJ) and then let them work on your jaw. There is an external and internal part of the therapy. The therapist will of course wear gloves for that part. This really works. I've had it done many times and I'm a neuromuscular therapist myself. If you live in GA I can recommend several people.
