I don't stretch it just causes so much pain and the delayed pain is worse then the time. I think for me my rsd area is so sensitive and also from not moving it certain ways and lack of range of motion that causes extreme pain. I think any type of new movements should be done slowly so the body can adjust. Have you tried going into the pool and doing movements in there?
My pain doctor once said that range of motion and strength training is so key in recovery from rsd. The problem is that it is like a dog trying to catch it's tail. When you do these movements the pain gets so high. That is where treatments or meds come into play so it can enable you to be able to do proper movements. Hope you feel better
