Dizziness is a common description for many different feelings. The feeling of dizziness, or a “dizzy spell,” may be very familiar to an individual, yet difficult to describe. Vertigo is a medical term to describe the feeling of spinning, whirling, or motion either of yourself or your surroundings. This is the same feeling you might have after getting off a merry-go-round or spinning in place. Several diseases of the balance organs of the inner ear can cause vertigo, or it may be a symptom of a tumor or stroke.
