Dizziness & Vertigo Support Group
Dizziness is the sensation of instability. Vertigo refers to dizziness with a sensation of motion. Vertigo is more likely than other types of dizziness to be associated with nausea, vomiting, or double vision, to occur even when lying down, and to feel better with the eyes closed. If you are a frequent sufferer of dizziness or vertigo, join the group and find support.
If they just do some testing, you might be ok. However, if they do something like the epley maneuver, you are supposed to keep your head still for hours after the procedure, so driving wouldn't work.
