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.
Sometimes, the calcium crystals in your inner ear break looseâ either because of an ear infection, a bump on the head, ear surgery, or aging. The crystals can then travel into one of the semicircular canals. When you move your head, these misplaced crystals can shift position.
