No to Stimwave, but I can tell you about Nevro SCS. I had wires and device implanted in October and it was the best decision I ever made! I finally feel fantastic. I did the trial and it was outstanding. I have 2 small scars on my back, one where the 2 leads were placed in (around?) my spine. The second is on my left flank where the device is implanted. I use a charger (looks like a drink coaster with a wire tail) placed over the unit, and when I'm not using it, it stays plugged into the wall I've had Harrington Rods, fusions, 6 screws, you name it. Today? I haven't felt this good since I was 15. I'm 63 F.
