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. You may find it difficult to walk, stand, or keep your balance.

Causes for vertigo include problems with nerves, blood flow, and the inner-ear.

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