@anklesurgeryguy My sister and my daughter both did have advice either from their doctors or a physical therapist, I forget which. I remember one thing to do was to whip their head to one side very quickly, a few times. I believe my sister did have a couple of recurrences of it but she has not recently - this was probably sometime around 2012.

Interestingly, at that time I was working and in the same time frame, my boss had vertigo! We even pondered if it actually could be caused by something that can be transmitted from person to person. It just seemed awfully coincidental to know three people with it. They were not close to each other at all geographically, but I am thinking something that goes around, as the flu does.
