Aside from being the name of a classic 1958 Alfred Hitchcock film (with Jimmy Stewart and Kim Novak), vertigo is a feeling that you are dizzily turning around or that things are dizzily turning about you. Vertigo is usually due to a problem with the inner ear. Vertigo can also be caused by vision problems. The word “vertigo” comes from the Latin “vertere”, to turn + the suffix “-igo”, a condition = a condition of turning about). Vertigo is medically distinct from dizziness, lightheadedness, and unsteadiness. See: {{}}Dizziness, Lightheadedness, and Unsteadiness.
