I think that is what my neurologist meant. Since it is so specifically located near the tip of the calcaneal nerve and is only an electric shock feeling without any other symptoms anywhere, it is not spine related.

It literally feels like a strong static shock like we all get when touching someone in dry weather.

It happens when pronating during weight bearing, during the midstance, and push-off. Zap-Zap-Zap.

I am nearly recovered from severe neuropathy of the hands and feet and this symptom is very new. My neurologist and I hope it is not the start of something new.
