For almost two weeks now i have been feeling lightheaded, with a slight headache and blurry vision, in addition i feel some pressure in my ear. I have been checked out by the ER (BP, bloodwork, pulse, heart rate, basic visual/ear exam, Urine test) they said everything appears to be normal. However they did find a little buildup of earwax in my ear. I don't think that would have anything to do with it though. but I am still concerned why i am still feeling lightheaded.
