Hello @ws4k , I had a Nevro stimulator implanted in August of 2017 because of general lower back pain that couldn't be relieved through any conventional means. I've had basically ZERO pain since then. Every month or so the last 5 bones in my back get misaligned and I need about a 2-3 minute adjustment by my chiropractor, and then: good as new! I charge my stimulator through induction every day for so – sometimes I forget for a few days but it doesn't matter. They tell me the effect doesn't "wash out" for a few days after the battery depletes. I live a normal life, virtually free of pain for the first time in 27 years. I've travelled to Europe several times and even to S. America and the Galapagos. I pack my charger in carry-on so as not to lose it. I even played 3 rounds of golf for 3 consecutive days just 8 weeks after the device was implanted. I do wear a back support when I play but only because my bad swing puts undue pressure on my back…and entire body 🙂 Since I've had the implant, Nevro had developed and had approved a newer model that is smaller. I think they just developed a smaller battery. Oh, and no parathesia with either device.
