I am new to all of this but I thought some of you may have some answers to some of my questions. My 65 year old father in law is contemplating having a neurostimulator (Medtronic) implanted for chronic lower back pain and pain in both legs due to stenosis in the spinal column from chronic osteoarthritis. We are also dealing with him being overweight and trying to lose weight along with diabetes and COPD. Can you give me any advice as to how this has helped you or if there are lots of problems with them etc.? He is trying his best to lose weight but exercising is a no-go due to his pain. Will he have any more success with that after an implant or is that kind of activity not allowed due to leads being moved etc.?? Also can you really tell how it is going to work for you from the days of the test stimulator? Does it take a few days to get used to it? He has had one hip replaced and knees that should be replaced. I am a bit concerned about the MRI implications of the implant as well. Any information that any of you can give will be most helpful to our family. Thanks!!
