I have idiopathic peripheral neuropathy in my hands, lower legs and feet. Biopsy confirmed c-fiber neuropathy. My feet are always very very cold. My neurologist says she can feel the pulses in my feet so doesn't think that my pain is related. I have an infrared sauna, and even after I've been in there for 45 minutes, my feet still feel cold and I am unable to sweat. I'm getting pretty worried about this. I also have white patches on my arms which my doctor describes as "poor capillary filling". Also have fibromyalgia and have read about "neurogenic inflammation".

Any thoughts?
