When I had my test with one the only thing was some numbness where the wires came out for the test and it’s still there they had the wires coming out of my back about two thirds the way up and I still can’t feel my wife touching me there but that’s a small price to pay to find help I know that they have helped a lot of people I just wasn’t one of them but as far as the pain in my case it did not change it so I hope that this gives you some hope that you will be okay and there’s more things that can be done to help you good luck and God’s speed
