symptom
vertigo
also: vomiting
a condition in which a person has a false sensation of imbalance and of the surroundings moving. It is commonly a sensation of spinning but may be as if the ground is tilting. The semicircular canals of the ear are fundamental in the maintenance of balance, and vertigo is generally the result of some problem with this mechanism or with the appropriate centres in the brain.
