Hi, I am looking into a PNS, a peripheral nerve stimulator, it does not go on your spinal cord but rather they implant leads which direct impulses to the affected areas of pain. I have NOT had anything else that worked and this is my only shot at relief. I have been researching it and have talked to 2 Neuro surgeons about it and they think it might really work. Read about it on the Internet and talk to your dr. Don't give up!
