This is great. I have had PN for a couple of years. Numbness only. I can live with it. I was sure it was the start of diabetes 2. I finally went to the doc. Xray showed a problem at my upper spine!!!! I was soooo happy....sounds silly i know but its much better than diabetes. I am 72. I am a USA expat in Peru. The medical system is very poor. Stone age poor. This is why I'm doing this research. As long as it is not something that will worsen I can live with it. And it comes and goes. No pain, just numbness in my toes!. Gracias!
