@patrick17 there is absolutely no doubt the devices had a positive outcome for pain management, especially with the damage I was left with following earlier Spinal trauma. In this respect I highly recommend them. It was just very unfortunate that it meant I could not have an MRI which would have picked up the other deficits I was suffering from earlier.
I can only hope that future developments in pain management come up with a similar device that is MRI compatiable because they really can be very beneficial.

In terms of the different types, the two brands were very different. The Medtronic ones I could feel the tingling in the areas the device was programmed to focus. The Nevro was a high frequency one so I couldn’t feel it working. In terms of the two different devices the Medtronic was good in the sense that each time the cycle stopped/started I would feel it kick in. Of course over time I became semi conscious of this happening so there was no thought process about it. If my pain was really bad I could use the remote to increase or change to another program to seek relief and would feel it tingle faster, stronger etc... The Nevro gave better pain relief for me overall even though I couldn’t actually feel it. Again I could increase or change the program to fit with the varied levels of pain. It really helped with nerve pain in legs/back and neuropathy in feet.
I do remember when it was suggested we try the Nevro and I read all the info, I thought ‘I’m not sure how this is going to work because if I can’t feel is working how is it going to change the pain?’ I was was pleasantly surprised how much it did help.

Whatever you decide make sure you research and ask questions of Drs and other patients who have used pain devices - good luck
