Labyrinthitis: Inflammation of the Inner Ear

Labyrinthitis is a problem inside the inner ear. It happens when the labyrinth, a part of the inner ear that helps control your balance, gets swollen and inflamed.

Labyrinthitis may cause sudden vertigo. This makes you feel like you're spinning or whirling, even though nothing around you is moving. Labyrinthitis may also cause hearing loss or a ringing in your ears (tinnitus).
