At least TMJ can go away.That is about all that you can do with chronic pain. Stay a step ahead of it. We were taught in training that it is better to control pain before it settles in. Pain responds better if you treat it sooner rather than later.
Sorry to hear that you are still having pain from that. I'm sure I either have that going on with my right side of my jaw or osteo. Don't think I want to know which it is.
