You made me think, I have neuropathy and I had a shingles vaccination about 10 years. I know the vaccination was first, I can't remember how long after that my neuropathy started. It began in my feet, then my legs and now in my hands. I' m not diabetic, don't smoke, not a big drinker, have been on aa heart healthy diet 40 years and a low carb diet 50 years. My dad died at 65 from heart disease and my wife is a diabetic, low carb has been a natural part of my diet since we married 50 years ago.
