are you staying well hydrated? Be sure you are drinking an adequate amount of fluids...you could possibly have vertigo. I get the same feelings, feeling fait and nauseated and feeling like i'm going to pass out. Dr didn't know what else to do accept give me a med for my nausea. It only happens once in a blue moon but believe me I know its a horrible feeling, mine get so bad now that I actually do throw up and STILL feel dizzy and nauseaus after!...I would go to an Eye ear nose throat specialist and see if they cant help you..i'm thinking about doing the same
