Make sure they do a test to see if it's going to work before they do the permanent installation. If it doesn't work ask about having an intrathecal pain pump installed instead. This pump has a catheter that runs up your spine and leaks tiny amounts of Narcotics directly into your spinal fluid and is tremendously effective without any of the side effects of Narcotics. Meds delivered this way are 100 to 300 times more effective then things that you put in your mouth and have to run through your digestive system. I've had one since 2017 and it has made my life worth living again. It's not perfect, it doesn't take away all your pain but it also doesn't leave your stupid and sleepy like 230 grams of Narcotics a day will do.

to quark - I had a Nevro stimulator implanted last October 2020. The trial (which I wore on a belt for a week) work beautifully. I am still in the process of adjusting the implant, but I've already achieved about 50% improvement. Mine is MRI compatible and I have the proper medical proof to board a plane. btw - my implant is for spine i.e. scoliosis, spondyllisthesis, 3 level lumbar fusion, and therIe are 6 screws in there too. I'll try to answer any questions you have.
