I have chronic pain in my toes of my right foot from surgical scar tissue and nerve damage from 2 prior surgeries. during the trial period, which lasts 5 to 7 day trial period before they insert the battery (generator) in your body. They say if you get 50% relief wth the trial, you should get a permanent one installed. I'm not sure if I got 50% but the doctor and the Boston Scientific representative kind of convinced me to get the permanent one. I think I got only 25% relief. Plus with Boston Scientific you have a little parathesia that bothered me. After 2 months I had the permanent removed. Not a big deal. Perhaps in hind sight I should have gave it more time. With Boston Scientific you have to charge the battery every day for about 30 minutes. There are other spinal cord stimulators, i,e. Abbott, Nevro and Stimwave. My problem was in my foot (toes) maybe Boston Scientific is not the best for chronic pain in the feet. Perhaps you should interview other doctor's who do the other devices. Ask to talk to a few of their patients who had SCS installed at least 6 months ago. Some doctor's will give you phone numbers to talk to them to see how their experience was. I'm interviewing other doctors before I make my next move. Good luck!
