I remember something like that back in high school, although I never did go to the doctor for it -- just, periodically, the world would start spinning and I'd turn faintly green. Lasted for several weeks, then went away and hasn't ever bothered me since. (Well, okay, I did have dizzy spells for several months after the accident two years ago, but that was concussion.)

I hope yours goes away quickly and doesn't come back.
