i have a similiar axonal peripheral neuropathy caused by toxins for 11 years now. i dont know what your symptoms are or what you have tried so there isnt much i can comment on about it. Its not going away for me and has steadily progressed to the point that my last neurologist appointment about 2 weeks ago, when the neurologist did the pin test and vibration test for sensation i felt absolutely nothing below the knee. didnt even know when he was touching it or not. my eyes were closed. definite downturn from last year when i could feel somethings dully on the upper calf. its been steadily getting worse. My legs and feet are numb but yet painful. my hands are numb to a lesser degree but not painful in itself but if i bang them or smack them or try to open something, the pain response is greatly exaggerated.
