Benign paroxysmal positional vertigo (BPPV) is caused by a problem in the inner ear. Tiny calcium "stones" inside your inner ear canals help you keep your balance. Normally, when you move a certain way—such as when you stand up or turn your head—these stones move around. But things like infection or inflammation can stop the stones from moving as they should. This sends a false message to your brain and affects your balance.
