Had the same problem with electrical type shocking that lasted for about five minutes. I’ve had X-rays to see if the leads had shifted but they hadn’t. Nevro is useless when it comes to patient after care, no follow through at all. I’m currently on Oxy 15mg 2x/day which takes the excruciating pain to a bearable pain but still can’t walk through the entire grocery store or walk 1/2 mile without the pain getting worse. Currently suffer with non-stop groin pain on left side (the implant was installed for right side pain) and it’s nonstop lower back pain 24/7. There has to be a better way of life than this. I’ve suffered with legs giving way due to electrical type shooting pains that stem from the lower back, run through the groin and down the front of my legs making my legs buckle and ultimately falling.
My heart goes out to you as I know exactly what you are going through. I haven’t found a solution yet and my unit is at one on the ladder and one on the program, every other programs make the pain 10 fold.
All I can suggest is to keep on calling your device’s rep to try and get some answers. Did they redo the surgery to place the leads in the correct place?
