polyneuropathy. It has just been sensory neuropathy involving the sural nerves for the last 10 years, but apparently sometime this past year it is involving motor nerves on my left foot, my last EMG/NCV was in May. I expect the right foot will follow suit. I hate the fact that it is idiopathic. To me at this point that is the worst thing, since there is no one thing that points to the cause, I feel pretty helpless.
