Hi. Mine preop was in the joint. Grinding, crunching, mostly when opening or yawning, but also when chewing. A few months before my surgery the pain was constant. I also had muscular pain in my neck and upper back. Now, postop, I have none of the old pain, but new, strange pains. Right behind the joint, under my ear, and through my cheekbone. The back and neck still hurt too. I've noticed everyone's experience and pain is different. Even 2 people with the same problem.
