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.
