I’m so sorry for your agonizing pain as well. My unit is from Abbott Labs, and I received the surgery from the Kansas University Spine Center. It was my doctor’s idea; I had no knowledge about it. It’s rather new. It’s not an easy subject to broach with others. I have two leads - one is for S2 and the other is for S3; both left, and I have an implant in my left flank (the size of a double stuffed Oreo). Every couple or few days, I am to increase each area by one. I feel the area and pain changing. Even if I get this pain down to 40%, that would be wonderful. I hope you find your answer!
