Vertigo (from the Latin vertigin-, vertigo, "dizziness," originally "a whirling or spinning movement," from vertere "to turn") is a specific type of dizziness, a major symptom of a balance disorder. It is the sensation of spinning or swaying while the body is actually stationary with respect to the surroundings.
So, I get this dizziness every so often, but lately I have it frequently. As I was sitting at my desk here at work I felt it again, and I'm wondering why I get it so often. Sometimes it happens when I'm driving my car, when I'm lying down in my bed, or just sitting here at the computadora. Anyone else out there feel it too?
