What could cause rsd type symptoms?

Many things: Rsd, now called complex regional pain syndrome (crps), can be caused by minor trauma (one of my patients was opening a box when he developed crps in his hand), fracture, other major trauma, brain injury, spinal cord injury, stroke, surgery, nerve compression and inadvertent needle placement injuring a nerve. It can be treated conservatively. See your doctor for referral to a good pain specialist.

Endstage muscle dz.: In the 50s there were a few md pioneers who concluded that chronic tissue pain was caused by numerous trigger points in muscle fibers causing the muscles to contract compressing nerves, vessels and alter the flow of lymphatics. Rds develops from this myofascial dz. Early therapy is the key with myofascial release therapy with massage, tissue therapy, trigger pt injs w Lidocaine and acupuncture.
