Here's a nice triggerpoint chart for the upper body that might be of help for some of you -

Many use a tennis ball or other ball sizes against a wall or laying on them on the floor to find the triggerpoints and apply the pressure.

Found it!
 

I am now a massage therapist trained in medical massage therapy, I did this to treat myself and where this goes from here... I'm not real focused on that right now.

I am not a doctor (nor have I played on on TV). I cannot diagnose or prescribe any drugs or methods or tell you that this will work for you. This is all my OPINION and should be taken as such. DO YOUR OWN HOMEWORK.

I FOUND IT! The cause of my TM. It only took a total of three weeks of palpation and experimentation to find two small muscles in the back of my head that caused my TM.

I located Rectus Capitus Posterior Major and it was a little bit sore. The reason I found that area is that when I would push on that location on my head my TM would sometimes stop in its tracks. I know that if you press on a trigger point it will stop the referred pain it causes. I felt that treating that location like a trigger point was worth a try. Does your TM strike you less when you lie down?

My TM was 30% better after I worked that trigger point area, even though I could not find an actual trigger point there to start with. The next day I found that the release of that muscle had relaxed an area next to it (Oblique Capitus Superior) and I found a trigger point there as well so I worked that muscle next. That was 10am this morning and by this evening I could eat without shocks to the face, showered and washed my face, brushed my teeth, flossed, and kissed my wife good night, things I haven't done in weeks now.

Not much movement on this forum and I'm moving on to tell others what I have found. If anyone wishes to discuss this with me further I will try and look in on this forum once a month or so, or you can let me know there is a message here by sending me an email **. Don't put up with TM any longer! My discovery may not work for you but I have traceable, documented, science as to why it worked for me, and what I found, and why doctors don't always know.

For what its worth and smiling again,
KBCMT

No disrespect meant, but trigger points don't do a thing for ON. When its bad, touching the nerve sets off lightening like shocks of pain that can occur in the neck, scalp, forehead, and sometimes the temples. The pain occurs where the nerve travels and is not referred pain from trigger points. When mine is really bad, just my hair moving is painful.
