Hello, yes I have had covid three times. I also experienced the feeling of electric shock. But I had the most of them in my neck, head, arms, hand, and fingers. Mostly in the upper body. I started to take these to help with vestibular migraines and them seem to go away. I developed vestibular migraines after getting covid in 2020. I had vertigo, dizzy, lightheaded, etc. I take vitamins everyday or every other day to help with this. And then I noticed that the electric shocks slowly went away.
