I have RSD in my right leg with it spreading to my left leg. I was told by my physical therapist who I have been going to for 7 years as well as my pain management doctor whom specializes in RSD that exercise is extremely beneficial to a patient suffering from RSD.

Its why they almost always prescribe physical therapy. He explained to me that because of RSD being a disease that so often takes over the body and its degenerative effects on muscles and such that it is crucial to continuously use them to fight it off. He did say to always keep to what your body can handle and he highly highly encouraged me to check with a physical therapist to be sure I was doing appropriate exercise without causing damage.

Obviously contact sports aren't beneficial to my condition but routine exercise that my body can tolerate such as treadmill, weighted leg lifts, the shuttle and so on are really good things to keep up on. I for sure would talk to my doctor and even ask to be sent to physical therapy to see what they suggest. Good luck and God bless.
