Why do some people feel electric shocks? Is it because of Vitamin B12 deficiency?

These shocks, though technically not electric, are sudden, brief feelings of sharp, tingling, or burning pain. Those who get it, often describe it as a small jolt of electricity running through their body. These sensations can take place suddenly, or after certain movements, and can occur multiple times in a day, usually occurring for a few seconds, though they might be longer.
