It certainly sounds alot like the Vertigo I get, I've been getting it for years, it was one of my first symptoms. I feel like what you said alot of the time, be careful, when I got it at first it would hit me without warning, I would end up on the floor or if I was outside I was on the ground.
When I get vertigo, which is quite often, I cannot move my head and my eye move back and forth, not always but when I'm having a bad spell.
