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. Moving your head to
the same position again may trigger another episode of vertigo.
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.
