I had the nuerostimulator implanted on 9-24-2012 and it hasn't worked at all. I have had it programmed 3 times and going tomorrow for X-ray to see if the wires have moved, then reprogramming again. I'm not giving up yet, but if they can't get it right soon, then I will have it taken out for sure. A little upset because the trial worked great. That's the reason I had it implanted in the first place.
