What is vertigo?

 Vertigo is a symptom of a physical disorder or disease of the body. Vertigo is characterized by a sensation of dizziness, fainting, partial loss of consciousness, loss of equilibrium, or leaning to one side.
   Simple vertigo usually lasts about two weeks, but other cases of this distressing symptom last until correct diagnosis is made and the cause is correctly treated. Infections, eye trouble, brain injuries, bad teeth, drugs, and seasickness all produce different degrees of vertigo.
