I believe, from all I've read, that the symptoms are varied. My feet, for example, burned slightly on the outside edge of the sole. This was some 10 years ago and intermittent.

Here is a link (one of many available.)

All my other symptoms come and go, but that makes sense to me, as the circulatory system could be the culprit in my case, not nerve damage. I have to factor in my age. I'm more concerned in keeping things moving than knowing exactly what is causing the problem.
