Long COVID tingling, zapping and brief blackouts, still returning with illness a year on

Summary

This person had COVID three times in 2022, the last on Christmas Day, while away from home with a newborn. During that infection they felt tingling, popping and zapping with every movement, blacked out briefly when turning their head and feared passing out driving home. The sensation returns whenever they get sick, about four times in the past year, and lingered after a COVID booster; a year later it still returned with illness. A doctor suggested vitamin D.
