Thanks for all the info.....I definitely look like a non-length dependent sfn case in my mind, I am going to ask for the skin biopsy tomorrow when I see the neuro, just to confirm.

I did wonder though....can any motor involvement be included at any level? The reason I ask, I have muscle faciculations, quite a few, more than "normal" people have. And sometimes feel a slight internal tremor when I awaken in the morning. No weakness though, and my EMG was perfect last year.

I am starting to fear the motor aspect moving along as neuropathy progresses, because of weakness, etc......Scares me!

Mine is idiopathic......all this paresthesia, etc....happened overnight, for no reason! Hard to accept, no reason, I keep thinking they missed something!
