Benign paroxysmal positional vertigo (BPPV) is a condition caused by problems in the inner ear. Although its cause is not certain, it is most likely due to a build up of calcium in the semicircular canals of the inner ear. The principle symptom is a sudden, intense feeling that either one is spinning or the room is spinning, which usually occurs with movement of the head. Other symptoms may include nausea or vomiting. Treatment for this condition includes the medicine meclizine or repositioning techniques, The Epley and Semont Maneuvers, employing gravity to move the calcium buildups that are causing the condition.
