I have had two spinal cord stimulators. The first one helped a lot for abou3 years. Did they mention the trial to you? Fairly simple procedure done in the office. You have a temporary leat placed along side the spinal cord and the battery pack worm for 3 to 5 days. You evaluate what, if any, pain relief you get. They are looking for at least 50% pain reduction. Then you decide if you want the permanent implant. I got about 70% pain relief. After the trial, it was about 50%. But, that, along with my pain meds allowed me to resume almost all previous activities, including cycling, which I had not been able to do for almost two years.
Hope this helps you. I also just had the morphine pain pump surgery, which is going well so far. Besr wishes and prayers for wisdom for guidance to the right procedure.
