Well I have RSD and PN and PT with a therapist did not work very well with me. What has helped me is increasing my ability to do certain things like my walking time which I slowly increased like 5 minutes a week or two till I built up to a better time. I had a hard time in the pool but many find it of great benefit so may try again. I know for me if I don't use it I loose it but it is finding a happy med cause otherwise I pay in terms of long term pain.
