I feel for you. My arms got so bad while sleeping that I wear long wrist supports to bed every night, at the suggestion of folks on here, especially @johnbishop . Something turns my arms “off” very easily, and some stools (especially metal) seem to turn my legs off sometimes. It’s almost like a switch that turns the power completely off in my arms or legs, and takes a while to shake it off and get the current flowing again. It seems my nerves must be easily compressed. I can’t sit at a computer for long. It seems no matter how I position my arms, elbows, or wrists, they become unusable very quickly, and I try them out often, can’t stay on a computer more than 15 minutes at a time. My last EMG on one arm and leg for PN was 2+ years ago, and I recall a note to the effect that due to PN, carpal tunnel couldn’t be distinguished but was possible. But my fingers really affected are my pinky & ring fingers on both arms, and I know those are the ulna nerve system vs carpal. But either way, they say it’s PN and I need to live with it, so I took the advice on buying wrist/forearm supports for sleeping, and I have had a 95% improvement in not waking up with the dead, non-moving arms from compressing them while I sleep!
