I sometimes suffer from bouts of vertigo. Not sure what brings it on but it usually doesn't last more than a week. Except a few years ago just before I was diagnosed with LADA. Come to think of it that was the first time I ever had vertigo. My regular physician thinks it's fluid in the ears from upper respiratory infections and colds. But I've had those in the past, pre-diabetes, and I never got vertigo. Perhaps it's age. My mother also gets bouts of vertigo; sometime for weeks. I have a theory of my own. I notice that the vertigo gets worse when I drink large amount of coffee. This week when I got the vertigo, I quit drinking anything with caffeine and the symptoms are slowly going away. Meanwhile my hot beverage in the morning has been White tea.
