Ive had the same symptoms for years...it will go away for a few months & then...bang! its back. i also get very nauseated during the dizzyness..its more like the room is spinning, I get cold & clamy & shaky, my heart beats fast..feels like im gonna vomit. dosent usually last long, but it makes me NOT want to socialize.
I am yet to be diagnoised.
I have tryed the eply manovre(sp) from pictures on the web, b/c i think its an inner ear thing.
good luck to you.
