Have you tried massage therapy or better yet, acupuncture (or acupressure). I used to be a massage therapist and shiatsu practitioner. These modes of therapy, particularly acupuncture and acupressure work on the nervous system and help with many ailments. Using acupressure, I was even able to provide pain relief to clients with severe fibromyalgia who could not tolerate massage. After treatment, some of them were even able to get a mild massage.
If you are able to afford it, I highly recommend it. And out of the 3 choices, I would recommend acupuncture first. It's the most effective for relaxing the nerve pathways. If I could afford it, I would go once a week.
Hope this helps.
