Benign paroxysmal positional vertigo is a condition caused by problems in the inner ear. Although its cause is not certain, it is most likely due to a buildup 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 employing gravity to move the calcium buildups that are causing the condition.
