Poss Vestibulitis: If you are also having symptoms of a Sinus infection, it is likely that you developed secondary Vestibular neuritis or labyrinthitis. These are disorders that result in inflammation of the inner ear and the nerve connecting the inner ear to the brain. They are usually caused by a viral infection, leading to vertigo, dizziness, and sometimes visual disturbance. See Dr if symptoms persist or worse.
