Vertigo is a disorder with various fluctuating symptoms: vertigo or strong dizziness, tinnitus, hearing loss and the sensation of pressure or pain in the affected ear. Vertigo usually breaks out suddenly, affects most often only one ear, and can arise daily or as infrequently as once a year.

Typically, the attack is characterized by a combination of vertigo, tinnitus and hearing loss lasting several hours, with frequencies, durations and intensities of the discomforts varying from patient to patient. Periodic attacks of vertigo (or dizziness) are the most disruptive symptom to the patient. It occurs in the form of a series of attacks over a period of weeks or months and produces nystagamus, nausea, vomiting, sweating and all the symptoms usually associated with extreme motion sickness.

Hearing tends to recover between attacks, but over time it becomes worse. Overall, Vertigo is a progressive disease.
