When my Medtronic’s unit seemingly died, I swapped out the Medtronic’s battery for the NEVRO battery. Did not provide relief either. Upon testing, it was suggested that the paddle lead had developed issues, including sever burned out electrodes. So, no relief. The old paddle along with everything else was removed in May of 2023. Tried new SCS but too much scar tissue to get a new lead in place. So now it’s all on this pain pump that I’ve been trying to get adjusted for over two years.
