I do not suspect that you have a pinched nerve
for the story you have related ( a pinched nerve
should give a focal defect, not the whole body). I would recommend that you get and EMG(nerve muscle test), QSART test (for autonomic neuropathy) and screening blood work (to look for other causes than diabetes) including b12, ana, tsh, monoclonal protein in serum and urine, copper level, ceruloplasmin, vitamin E level, and B6 level. I hope this has been helpful.
