Egoscue will help. Pain Free or The Egoscue Method of Health through Motion. Through personal experience of chronic pain I know this. It works that well, I trained as an Egoscue Therapist. I am also a Yoga Teacher - Egoscue will sort out the problem first, then do yoga.
Egoscue is the answer! Believe me through chronic pain and dysfunction, I came to the method. It actually works! And worked so well for me, I've trained as a therapist, it is truly wonderful to be able to take this method to other people.
