The doctor will ask you to describe your dizziness, whether it is light headedness or a sensation of motion, how long and how often the dizziness has troubled you, how long a dizzy episode lasts, and whether it is associated with hearing loss or nausea and vomiting. You might be asked for circumstances that might bring on a dizzy spell. You will need to answer questions about your general health, any medicines, you are taking, head injuries, recent infections, and other questions about your ear and neurological system. Your physician will examine your ears, nose, and throat and do tests of nerve and balance function. Because the inner ear controls both balance and hearing, disorders of balance often affect hearing and vice versa. Therefore, your physician will probably recommend hearing tests (audiograms). The physician might order X-rays, a CT or MRI scan of your head, or special tests of eye motion after warm or cold water is used to stimulate the inner ear (ENG - electronystagmography). In some cases, blood tests or a cardiology (heart) evaluation might be recommended.
Not every patient will require every test. The physician's judgment will be based on each particular patient. Similarly, the treatments recommended by your physician will depend on the diagnosis.
