@arcuri24 , sorry to learn of your problems. I would suggest that perhaps you were too aggressive in trying to build up your glute muscles. Anytime you start working a muscle group, you have to start slowly with small weights. Otherwise, the muscles will cry out in anger and pain. At least you do not have pain with your neuropathy(I assume you have been tested). My neuropathy created steady buzzing, tingling and pain. Every step is painful. Were you monitored by a therapist in PT? The PT should know how to start you out in weight training. Perhaps disc problems are causing some of your back pain. I wish you well in your journey. Don't give up. There are answers out there. Get second, even third opinions.
