Dizziness/Vertigo: If blood is not getting to your brain as well as it should, or if there is even a subtle infection in the ear, one can experience dizziness.  There can be many causes, from blood pressure being too low, to stress, to heart issues and even depression.  Aside from those listed above, one of the more common causes that we often correct  in our practice is the derangement of cervical vertebrae that have been either directly affecting the flow of blood to the brain, or that are irritating the nerves that direct blood flow to the brain.  If caused by an ear infection, by aligning the neck the eustachian tubes (that lead from the middle ear to the throat) are better able to clear, allowing the ears to drain which decreases pressure on the balance structures in the inner ear, reducing dizziness.
