I was diagnosed with chronic vertigo after a concussion. You know the dizzy feeling you get when you stand up too quickly? It's that, but many times a day, often for no reason.
The biggest problem for me is being a passenger in a car. I think it has to do with my mind perceiving the movement, without my body doing anything to make it. As I'm fine when I'm driving, or when I turn the air conditioner on at high levels. I can't watch 3D movies, or sit off axis to the screen at a movie theater. It can also be set off by caffeine or stress or if I'm really angry.
I personally have never experienced any problems with heights. Though, I'm sure some people do. My reason for bringing it up is that often times people mistake acrophobia with vertigo. So when I tell them I have vertigo, they just think I'm scared of heights.
