Ménière’s disease – Wikipedia

Ménière’s disease (MD) is a disorder of the inner ear that is characterized by episodes of feeling like the world is spinning (), ringing in the ears (), hearing loss, and a fullness in the ear. Typically, only one ear is affected initially; however, over time both ears may become involved. Episodes generally last from 20 minutes to a few hours. The time between episodes varies.
