Van Neck disease

Ménière's disease (MD) is a disorder of the inner ear that is characterized by episodes of feeling like the world is spinning (vertigo), ringing in the ears (tinnitus), hearing loss, and a fullness in the ear. Typically, only one ear is affected initially; however, over time both ears may become involved. [Source: Wikipedia ]
