http://tinyurl.com/ag6np Re. Molik: Vestibular neuronitis Vestibular neuronitis is an inflammation of the vestibular nerve, which is located in your inner ear. The vestibular nerve carries balance signals from the inner ear to the brain. When this nerve is inflamed, it causes vertigo—a feeling that you or your surroundings are moving. Vestibular neuronitis often follows a cold or upper respiratory infection, suggesting that it is caused by a virus. Vestibular neuronitis usually occurs in just one ear at a time. Vertigo occurs suddenly and may continue even when the person lies completely still. It may be accompanied by nausea and vomiting. The vertigo often lasts for several days and sometimes takes weeks to go away entirely. Vestibular neuronitis does not cause hearing loss or ringing in the ears (tinnitus). The inflammation that causes vestibular neuronitis usually goes away on its own usually within 1 to 2 weeks. Usual treatment is to rest until vertigo symptoms go away. Severe symptoms of vertigo may be reduced with medications, such as antihistamines or sedatives.
