Thank you John. My specialist is still investigating as I have severe disc degeneration in my neck, but he also suspects SNF. I am wondering if you know whether anyone has developed SNF from this cause. Also do you know of anyone who follows the Protocol system of nutritional support for SNF. I am a big nutritional buff for health as opposed to drugs but as of now I do use tramadol for the worst numbness and tingling, especially at night.
