I have been feeling unbalanced a little dizzy for over a year had a ct scan my dr said it wouldn't be a tumor because i have no headache is this true ?

No tumor: Imbalance and neg. CT rules out tumor.Many causes of imbalance such as meds, ear infections or anything affecting inner ear, brain or low blood pressure. Balance depends on signals to brain from structures known as the vestibular system which contain the semicircular canal. Inflammation can initiate imbalance. See ENT doc. If diagnosis is Ménière's disease, he may use med to help.
