I’m 60 yrs old now…your post caught my eye about electric shocks. It reminded me of a time back in high school…I think I had 2 episodes of an electric shock in my neck. The first time I spun around thinking someone had done something to me from behind…but no one was there. I never had them again. Unfortunately I do now have idiopathic Neuropathy (7 yrs diagnosed)…I doubt it’s related.
