Vertigo (dizziness) is an uncomfortable feeling of motion when there is no actual movement. The feeling of motion is commonly described as spinning or whirling, but it also may include sensations of falling or tilting.

Vertigo can cause nausea and vomiting. It may be difficult to maintain balance, walk, or stand.

Causes for vertigo include nerve, blood flow, or inner ear problems.

Infrequent episodes of vertigo may not require treatment. If vertigo is severe or frequent, treatment will depend on the specific cause.
