Hi Baba
I was Dx with small fiber neuropathy by punch skin biopsy 2 yrs ago. All of my tests including 2 NCS/EMG, 2 MRI's brain and spine were normal. All of my blood tests keep coming back normal. Mine beast is idiopathic. (the worst kind Im beginning to believe because they can not find a cause, no cause no treatment, just drugs!) . Mine started with tingling in lower calves and burning under my feet, It has since progressed to my whole body. (arms, legs,hands, fingers, torso) I get bad buzzing, pins and needles, bad burning, etc...I'm still searching for answers..Good luck to you! Keep us posted....
