Welcome to Neuro Talk. Don't give up as PN can get better. The vitamines you are taking are the same ones my doctor put me on. In addition, I take B12 shots. I have not gotten any worse over the last six months. Mine is local to the foot and ankle. Consider seeing a physiatrist. They deal with this kind of pain, and deal with the whole person at a cellular level. I also have a lotion I use that helps numb the areas. I hope alot of folks will join in and try to give you some good suggestions. ginnie
