I had the Nevro device implanted 1 year ago. It gave me my life back. I started working again and was extremely happy with 80% pain relief. Then about 6 months ago, it stopped working. Have been reprogrammed 4 times with no improvement. Nevro rep and pain doc don't seem to have answer for me. I still get about 20% relief, so I don't want it removed and am thankful for the awesome 6 months it gave me, but wish there was an answer to get it working again.
