In the early stages of the illness, you may experience hearing loss, vertigo, and dizziness of varying severity. Some people may also notice a sort of 'aura' before they suffer an attack, which may include vertigo, migraine, sound sensitivity, tinnitus, increased pressure in the ears, and hearing impairment. Balance problems also frequently accompany this aura.
An attack may either last less than an hour or up to a full day. As it progresses, you'll likely suffer an intense bout of fatigue, requiring a great deal of rest to recover. In between attacks, you may also experience changes to your appetite, issues with coordination, frequent headaches, motion sickness, and nausea.
This may occur multiple times per week.
As you may have surmised, Meniere's is somewhat unpredictable, and therefore difficult to manage for both doctors and patients.
