I would go to an ear doctor and if that doesnt work a neurologist...I have a friend that gets dizzy from too much salt. Another from a poor diet and sleep and stress. Me I had "ear rocks" I forget twhat the real name is but an ear doctor will pick it up in a minute... I cant imagine that an ear infection would make you pass out though...to me it sounds like something else...it seems to me a lot of people get dizzy and it goes away and they never find out what caused it to begin with..
