Do your research, and find out which company offers the SCS to combat your specific pain.
The pain management doctor advised Abbott.
I was advised to have the "paddles" inserted, to allow the pain to transfer to the pain in a more controlled and efficient manner, as opposed to the lead wires. The paddles are more painful for recovery, and with what a surgeon told me, the lead wires are easier to implant. I didn't want easer for the surgeon, I wanted pain control.
As it is, the device isn't what I hoped it to be, and I will see the surgeon late December and discuss what and how, and possible removal. It will be almost two years since the device was implanted when I visit the neurosurgeon.
Also, interview the doctors. I interviewed three, one from Mayo. It is big money, and they all want you.

I had my stimulator implanted 16 months ago. It helped a little with my chronic back & leg pain. They had to reprogram it several times and I still have pain. After a few months I was having difficulty with emptying my bladder and developed chronic prostatitis. I’ve been complaining about this “ overstimulation“ for over a year with all my doctors. The only responses I got was we’ve never heard of overstimulation. Well, I shut the thing off and 80% of my prostatitis pain one away within 24 hours. I will have it removed in the next few months. I didn’t have a very good experience as you can tell.
