Renee again, stimulator wasn't bad. But expensive!!! Got really lucky with a great doctor who helped me with the cost. It's a in and out surgery, one day. The leads go in your spine, depending on where u needs the stimulation. Arms or legs. Then there is a generator in your butt, lol... it sends the signals to your spine. U control it with a ipod. I'm almost at the year mark and u just get used to it. Sometimes I still get healing pains in my back, but I'm glad I did it!
