Dizziness and Motion Sickness
Feeling unsteady or dizzy can happen due to poor circulation, vertigo, injury, infection, allergies, or neurological disease.
Affecting the inner ear, Ménière’s disease is a condition that causes vertigo (attacks of a spinning sensation), hearing loss, tinnitus (a roaring, buzzing, or ringing sound in the ear), and a sensation of fullness in the affected ear.
There are many tests used to help evaluate the vestibular and balance systems.
