I’ve also dealt with neuropathy for 20+ years. I’ve had electric shock symptoms from my sacrum down my legs for the entire time. After 17 years I had a rapid spread from my feet to legs to neck to arms and hands. It seemed that all the nerves in my body became involved. For me, the electric shocks seem to be a symptom of neuropathy, not healing but hard to know. I have severe carpal tunnel but I think it is also peripheral neuropathy because it spread and got worse along with all the other nerve pathways.
