Welcome to Neuro Talk. I am sorry that you are having so much trouble with PN. I too have it. I see a physiatrist, and take B12, Co Q-10. The B12 is injections. I did not believe suppliments could help. They did within a year, and made my pain much more bearable. Also take a few others like a pro-biotic, and tumeric for acid reflux. I believe there is hope, that you can improve. Keep in touch with Neuro Talk. You found a great place to find good people who will care. ginnie
