I had 2 dull pains on the left side of my head just above my ear, the next day i sneezed all day, then the following 2 months i had terrible head and chest conjestion, when that cleared up , i had a some achyness coming from my left ear then i had a dizzy spell lasted a couple minutes , now seems like every once in a while i have a weak dizzy spell with faint left ear pain. What's happening?
