Should I get a Medtronic spinal cord neurostimulator for my chronic back pain?

(I can't give any information from experience, but our surgeons put them in a lot for their chronic back pain patients, and they seem to work for them. From my research, instead of the pain signals, it sends a tingling feeling instead. I also talked in detail with one guy who had 2 placed, in different places, and he said it was the best decision he made.)
