Vertigo is the illusive sensation that you or the things around you are spinning, when in fact everything is stationary.  It can be combined with nausea and vomiting and will affect the ability to walk or even to stand.

Western medicine traces the causes to the inner ear or the balance centers of the brain.

Chinese medicine concepts and treatments for tinnitus and other hearing disorders were developed thousands of years ago.  The cause is traced to the Kidney system, since Kidney opens to the ears. (腎開竅於耳).
