Migraines are localised headaches that arise from tension in the body, and are often associated with light sensitivity. They can even cause vomiting in extreme cases. During a classic migraine, the headache starts in one area and spreads to that whole side of the head.
An occipital-orbital migraine involves pain running from the back to the front of the head, and an orbital migraine manifests as a stabbing pain behind the eye.
Childhood migraines, cluster headaches, exertion headaches and migraines with vertigo can also occur. Poor posture and stress can be a root cause, as well as bright lights and over-exercising.
Sleep often helps, and chiropractic care can alleviate tension in the muscles and manage headaches without medication.
