When a cause can be determined, BPPV is often associated with a minor to severe blow to your head. Less common causes of BPPV include disorders that damage your inner ear or, rarely, damage that occurs during ear surgery or during prolonged positioning on your back, such as in a dentist chair. BPPV also has been associated with migraines. Benign paroxysmal positional vertigo may go away on its own within a few weeks or months. But, to help relieve BPPV sooner, your doctor, audiologist or physical therapist may treat you with a series of movements known as the canalith repositioning procedure.
