Benign paroxysmal positional vertigo (BPPV) is a balance problem that makes you feel like you're spinning or tilting if you move your head a certain way. It happens when infection or inflammation keeps tiny stones in your inner ear from moving the way they should.
A vertigo attack usually lasts less than a minute. A doctor can move your head in ways that adjust the stones so they don't affect your balance. But even without treatment, the attacks will usually go away on their own in a few weeks.
