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 body normally maintains balance via an area in the inner ear that uses sensitive hairs to detect the movement of minuscule stones called otoconia, which shift as your body changes position. Occasionally those stones or other debris can become dislodged, causing dizziness, nausea, and loss of balance.
