Based on my (few) good and (many) bad therapy experiences, I think the approach outlined here makes sense, at least for me: http://physical-therapy.advanceweb.c...-Syndrome.aspx But where to find a good PT is the issue.

I've found this book an invaluable resource for trigger point work: http://www.amazon.com/Trigger-Point-...+point+therapy (check out the reviews). There's a lot out there about trigger point treatment, most of which doesn't seem to work for me, but this approach is straight-forward, gentle, and for me effective. I've had debilitating headaches and jaw pain (prevented my chewing food for about a year) and these horrible symptoms are well under control, although not gone, largely due to my following trigger point work as explained here. Unfortunately, I've yet to find trigger point work effective for the pain radiating down both arms and into the hands.

The "Cyriax release maneuver" and first rib mobilization have somewhat helped relieve symptoms.
