Dizziness is a word that is often used to describe two different symptoms: Lightheadedness is a feeling that you are about to faint or “pass out.” and Vertigo which is a feeling that you and/or your surroundings are moving when there is no actual movement.
When you have severe vertigo, you may feel very nauseated or vomit and may have trouble walking or standing, and you may lose your balance and fall.
What symptoms are common with vertigo and dizziness?

Dizziness: Dehydration, low blood pressure (not enough blood reaches the brain), or getting up too quickly
Labyrinthitis is inflammation of the structures of the inner ear due to a bacterial or viral infection
Benign paroxysmal positional vertigo (BPPV) is a balance problem usually seen in trauma like a car accident that makes you feel like you’re spinning or tilting if you move your head a certain way. It happens when inflammation keeps tiny calcium stones in your inner ear from moving the way they should.
