ost people understand that a pinched nerve in the lower back can cause pain in the leg. Through similar anatomical pathways, a pinched nerve in the neck can also cause pain in the head. Any dysfunction in this area irritates the muscles, nerves, and blood vessels that travel through the neck bones, or vertebrae, on their way to the head. A simple chiropractic exam will reveal whether a patient shows signs of vertebral misalignments. If so, a trial of care will reveal whether or not chiropractic adjustments will help YOUR headaches.
