Benign paroxysmal positional vertigo (BPPV) is caused by a problem in the inner ear. Tiny calcium "stones" inside your inner ear help you keep your balance. Sometimes these stones move into an area of your inner ear called the semicircular canal. When you move your head in certain ways, the stones in your semicircular canal move. Sensors in the semicircular canal are triggered by the stones, which causes a feeling of spinning.
