My initial diagnosis was idiopathic Small Fiber Neuropathy with an undetermined underlying autoimmune disease. Too make it even more interesting, the Neurologist tossed in early stage Parkinson. My favorite medical term "idiopathic" fancy way of saying we have no clue. I do think I have an autoimmune due to the constant severe chills and I believe the dull burning ear pain is related. The skin biopsy SYN-ONE CND Life Sciences is a proprietary skin biopsy that can also detect Parkinson (ruled out for me) and I was also interested in Lewey Body because my mother died from it. It was not even diagnosed properly until 6 weeks prior to her death. The SYN-ONE has a 95% accuracy, all my results were normal. Did you get this one?
