Yes, I had the Nevro device implanted last October. I had to have it re-programmed because there are many, MANY different programs that can be utilized, and now I have about 50% of the pain. I consider it a win. One minor inconvenience is having to charge it for approx 30 minutes per day. I sit in a recliner and place a (coaster-size) rubber paddle on top of the implant and just lay back. Its location is where your bum meets your back. You can choose left or right side. All-in-all, I would say yes, Nevro works.
