Looking for some help for my boyfriend who has CRPS Type I (also referred to as RSD).

Treatments include medication, physical therapy, psychological support, sympathetic nerve blocks, and or spinal cord stimulation. He's done everything but the spinal cord stimulation. I think he's afraid the doctor will make it worse. He had a cyst growing in his arm. He went in because he thought they were gonna drain it but the doctor told him he wanted to surgery because it was too deep in his skin. He went in for the surgery and the doctor cut a nerve. He ended up with nerve damage and the condition rsd/cprs. He had to have 4 emgs to determine he had nerve damage. I'm just trying to find something that will ease the pain and or help him. Also does anyone know of any good doctors who treat this?
