I'm not sure what the cause of your chronic pain is, but I would highly recommend reading John Sarno's "The Mindbody Prescription." I've dealt with chronic pain for years and it's the only thing that's had any effect. Please, please, don't write it off until you've read the book. Note that Sarno's work focuses on back pain, but it applies to all types of chronic pain (including migraines, which he discusses in the book).
