I had a spinal cord stimulator (Medtronics) implanted back in 2018. This was after a fusion of L5-S1 in 2017 (which did not improve my pain). I had some relief with meds but not great. The SCS was recommended by a neurosurgeon in nearby city. I had the trial (which ws done in pain specialist's office as an outpatient) which lasted about 4 days. It did help quite a bit (70-80%), so I went ahead with the permanent implant. It did not provide as much relief as the trial (50%), but helped to control the pain. Then, in 2021, it just stopped working. The was some thought that the paddle may have moved. Anyway, I just had it removed. Can finally go for an NRI to see what is going on with my back. Implanted pain pump is not providing any relief.
