Benign Paroxysmal Positional Vertigo (BPPV) - What Happens

Benign paroxysmal positional vertigo (BPPV) causes a whirling, spinning sensation even though you are not moving. If the vertigo is bad, it may also cause nausea or vomiting. The vertigo attacks happen when you move your head in a certain way, such as tilting it back or up or down, or by rolling over in bed. It usually lasts less than a minute.

BPPV often goes away without treatment. Until it does, or is successfully treated, it can repeatedly cause vertigo with a particular head movement. Sometimes it will stop for a period of months or years and then suddenly come back.
