I certainly would go ahead with the test but be VERY AWARE of any relief that you get during the test. I have had the nevro/HFX device implanted in my back for several months and have yet to get any relief in my back or my feet. I had a lumbar laminectomy in 1999 and have also been dealing with neuropathy in both feet for several years. I went to a pain management specialist and he recommended the device. I continue to work with the nevro coach but still don’t get any relief in my back or my feet. I am really disappointed with the device and will probably be talk to the surgeon to see about getting the device removed.
One word of caution. If you are currently using a stimulator (tens like unit) on your feet, it will NOT WORK with the nevro unit.

see if you can view my feb reply. I'm 86 y.o. and my symptoms sound like you might be my brother. Both back and feet wise. It did take me quite a while to get it "dialed in" buT it has reduced my pain considerably. If I don't charge the battery, as one MUST do, I feel its effects with increased pain, so I do know it works. I would encourage you to do it and hope you get a COACH, as Nevro likes to call the techs, who is skilled and dedicated.
