Jaw joint and its problems.

Do you clench your jaw? You might even not be realizing it. I had the same problem, then I noticed that my jaw was basically constantly clenched and I had to work on keeping it relaxed all day long.

Basically mentally and physically relaxing it and also massaging helps. But massaging and exercises can only help so much if you have the habit of clenching it all day long.
