Have you tried acupunture? I had a terribly sore shoulder last year that was severely limiting my activities. I went to the acupunturist, and I haven't had a problem since. Later, my DH was in a fender bender and hurt his back. After a few weeks it was still bothering him so I convinced him to go to acutpuncture, and he was completly better within 2 days. I know this stuff can't "cure" problems, but it can sure help with pain management.
