Vertigo. Motion sickness. Motion sickness occurs when the brain receives conflicting information from the eyes, skin pressure receptors, muscle and joint receptors, and inner ears. This can occur when you ride in a boat, airplane, car, or even on an amusement park ride. Nausea and vomiting are common with motion sickness. Benign positional vertigo. Calcium deposits in the back part of the inner ear, also known as the semicircular canals, cause benign positional vertigo. It usually lasts less than one minute.
What causes vertigo? The inner ear is filled with fluid, a nerve, and small organs. These structures help you maintain your balance. Vertigo may be caused by diseases or conditions that affect your inner ear or the part of your brain that controls balance. Any of the following can cause vertigo: 1  Small particles that float in the inner ear fluid move out of place and cause irritation. 2  MÃ©niÃ¨re disease. 3  Ear trauma. 4  An inner ear infection. 5  A neurologic condition such as multiple sclerosis, migraine, tumor, or stroke. 6  Panic and anxiety disorders. 7  Drinking a large amount of alcohol.
