I went through several sessions many years ago. It was a few years post RSD onset, and I was not not properly medicated at that point. I was guarding my upper extremity any time I was in public and causing more damage to my neck and back as a result. It didn't decrease my baseline pain, but it helped me cope much better and that in turn helped so that I didn't exacerbate things. I also learned to breath deeply as a coping strategy to relax which I still do unconsciously, btw. Meditation is another helpful tool IMO.

Will this provide a cure? Probably not. But, I'm very happy that I retain coping strategies many years later that I can call on as needed. Stacking treatments is something to try as well, if you're able...
