I have rsd from ulnar nerve damage to my right ARM. I had ulnar nerve surgery myself and subsequently developed rsd from surgery. I can so relate to your story and concerns. I have seen a pm specialist and have had several blocks, ketamine treatment, and ultimately a spinal cord stimulator. I find the scs stimulator helpful but doesn't take away the pain. I also now have pain in my back and neck from where I had surgery to implant the scs. So yes its some what helpful but also created other pain issues.....so please really do your homework and make an informed decision. I still have major pain, burning, spasms, etc in my right ARM and it hurts all the time. I ended up going out on disability and not being able to work anymore cause the pain. It's aweful. I'm sorry your going through this and wish you well.
