I was diagnosed withidiopathic (no diagnosed cause) peripheral neuropathy about 10 years ago and have most recently seen the head of neurology at Shands Medical center at University of Florida in Gainesville, FL; Dr Edward Valenstein. He left Shands about a year and a half ago and I have seen no specialist since that time. I am taking two vitamin b supplements and have been for 10 years. I also take Gabapentin and Tramodol daily to control the shooting pain in my feet. I am now experiencing a situation where two of my toenails are discolored and appear to be getting ready to fall off. Does anyone have experience or information about the onset of various effects one can expect from prolonged peripheral neuropathy?
