I had an SCS implant in March of 2008 in an attempt to control pain associated with DDD (L5/S1). The SCS was not successful for me and actually caused pain in a new location. When I turned the stimulator on I got pain near the lead (T9) that was pretty intense. I believe it did work on my leg and back pain, but the pain at the lead site was too intense to turn it on. My neuro wanted to go back in and adjust the lead, but couldn't guarantee that he would get it right. After much deliberation, I decided to fix the problem (with a fusion) rather than mask it (which is what the SCS is designed to do).
Best of luck with your decision.
