Balance problems are extremely common.

The balance organs in the ears
(P.D.Bull “Lecture Notes on diseases of the ear, nose and throat”)
The ears are an important component of your balance. The balance organs are made up of the three semicircular canals and the vestibule. They contain receptors which measure angular and rotational movements of the head and movement relative to gravity. This is fed back to the brainstem to coordinate movement. Both ears contribute 15% of our overall balance. 70% of balance is controlled by our eyesight and another 15% from joint and muscle sensors (Proprioception). All of this information is fed back to the Cerebellum or hind brain which controls our balance and movement.
