I had the Medtronic SCS implanted back in 2018. The trial gave me about 80% pain relief. The permanent implant gave me about 50% relief. Along with my meds it made an almost normal life possible...back to cycling, skiing, working around the property, etc. Then, in 2021, it just stopped working. There was some thought that the paddle mayhave moved or some of the electrodes on the paddle had shorted out. If you are out of other options, I would say to go for it. Preferable to back surgery which is a coin toss. Mat the Lord be with you.
