@justbob Bob, on the TENS unit, like Ray, mine is sitting in a box...somewhere. I was first diagnosed with PN in 2015 and while in PT around 2018, my physical therapist felt a TENS unit might help. He requested that my primary doc write a prescription for it so my insurance would cover the cost. I followed the instructions and after 10 days, it went into the box. No help. That's me, however, I suggest that each of us must explore any help possible because we all have different causes for our PN and who knows what might help. Ed
