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.
The patient wears a cervical collar to discourage head movements for 24 hours after the procedure. Ear rocks are small crystals of calcium carbonate called otoconia, which collect in the inner ear. If they fall out of place into the ear canal, they can cause vertigo.  Experts who treat dizziness estimate that about 20 percent of all dizziness is due to loose crystals â or ear rocks â in the inner ear.
