Would u know if u had vertigo or just lightheaded ?

Room spinning?: Vertigo/dizziness refers to a sensation that the room is spinning around you when you are in a fixed position. Lightheaded usually indicates that you feel faint or about to pass out. More importantly, use plain words to describe your symptoms to your physician if things get worse or you have new symptoms. http://www.nlm.nih.gov/medlineplus/dizzinessandvertigo.html
