How do you treat vertigo. and how do you get vertigo . how long does it last?

Depends on the cause: Vertigo is a symptom of an inner ear condition, sometimes during or following a viral infection, but there are several other causes. Often vertigo occurs with self-limiting conditions that require no specific treatment. But, if it continues to recur, it should be evaluated by a doctor to determine the cause. http://www.webmd.com/brain/vertigo-symptoms-causes-treatment#1
