I have had chronic TMJ for most of my life and I am 43 now.  It started from Junior high school or before.  I had to cut up foods like apples in order to eat them, sandwiches were difficult, twice my jaw locked open at the dentist. 

About five years ago, I started to have repressed memories of severe trauma and child abuse surface.  Once I started talking, it went away almost completely.  I just have a little "stretching" sound, but no pain.  My dentist is amazed.  This also happened with my chronic skin and allergy problems.
