Thanks for response and info on pinched nerve.
I have had biopsies in both feet and shins which showed SFN in left foot and peroneal nerve.
Last EMG and NCT was 3 years ago and polyneuropathy before then showed no motor response in feet, wasting, left leg weaker, foot drop.
I cant have MRI due to metal left from prior GI surgery.
I don't know if I call ....i have a sleeve/brace on knee to stabilize but may need to remove to see if help pain. I have been so nauious with pain today. Have ice and elevate now.
