Labyrinthitis is the inflammation of one or both of the ears’ vestibular nerves which are responsible for balance and spatial navigation. These nerves are located in the inner ear or the labyrinth. The symptoms of this inner ear disorder include nausea, dizziness, and the sensation that one is moving even when sitting or standing still. This is generally caused by ear infections; however, there is no known way of preventing labyrinthitis. The risk factors include smoking, allergies, high levels of alcohol intake, stress, and certain medications such as aspirin.
