I had some reeeeally bad TMJ pain some years back - at the time didn't know what it was, dentist thought it was an absess,
sent me to another dentist who thought the same thing, but wasn't sure, sent me to a specialist who was about to do an
abscess surgery through the side of my mouth, but took one more look at the x-rays and realized it was a bad case of TMJ.
The pain was, like you have, temples, jaw, neck, up back of neck, shoulders and very severe - I was in screaming pain.
Since I kept tossing my mouthpiece in the middle of the night, I had to find another avenue. When I was getting physical
therapy for my herniated disc, I told my PT about the TMJ and he gave me some AWESOME stretches to help with the pain.
Hope I can explain them well enough here in words:
1. Sit comfortably, take a deep breath and let shoulders relax as much as possible. Nod head to left (don't push it, just as far as it will go towards resting on your shoulder), then slowly look up and off to the left, keeping eyes looking up. This stretches out the neck muscles like you wouldn't believe. Again, don't push these, just enough to feel a stretch. Do the same thing on the right side.
2. Sit comfortably, or stand, taking deep breath to relax shoulders as much as possible. Turn your head as far as it will go w/out pushing it to the left. Take another deep breath, and while breathing out, look down to your left as if trying to look at your toes and hold. Repeat on the right side.
They stretch parts of the neck and shoulder that really hurt. I sure hope this helps. Whenever I have head, neck or shoulder pain from TMJ or the frozen shoulder I had, I do these exercises. Just a couple or few times on each side seems to do the trick! Sorry you're having TMJ issues... I know how much it sucks!
