J.S.
I get vertigo under a few different circumstances and have been prone since I was a child:
sinus infections (caused by illness like colds that progressed to sinus infection or sinus allergies gone out of control)
fluid in ears becomes unequal, like spinning down a hill
fever delirium
migraines
near-fainting as a symptom of Fibromyalgia
I try to stay hydrated to minimize risks associated the Fibro and migraines and I try to avoid changing positions too quickly from sitting to standing. If I do get dizzy I end up "holding on for dear life" until it passes and close my eyes trying to breathe through it like I did when I was pregnant and had severe morning sickness trying not to puke.
