Hi, I take Alpha Lipoic Acid and Acetyl L Carnitine supplements and they help with the burning, pins and needles and numbness in my feet since my small fiber neuropathy diagnosis. I now get new numbness in my feet when I walk too much or too long/far but believe it is tied to my lumbar spinal stenosis (not sure if peripheral nerves are being irritated or vascular impingement). Good luck! I know how uncomfortable this can be!
