Basically PN is like this:

1) try and not label yourself with diagnoses for the most part. For example, the medical literature often fights with itself, over naming things and goes back and forth with papers, about many things. Getting caught up in that really clouds the issue.

2) think of your nerves as an early warning system. If something sets them off, avoid it. In this case it is sugar, but it can be gluten, vaccines, nightshade veggies, other food intolerances, spices, heat, excessive cold or whatever.

3) if some activity sets you off, try and moderate that activity, or switch to another. An activity setting you off, suggests compressive problems in the foot, knee or back. This may lead to a diagnosis of a mechanical issue which may help in the long run. PNs like this hurt when you sit only, or only when you
engage in some sport, or only when you lie down, or when you walk, or whatever.
Make sure if you have a mechanical trigger, that you get your feet looked at with xrays, and other podiatrist testing to make sure you don't have arthritis in the joints, spurs, neuromas, or sesamoiditis in the balls of the feet.
