Headaches That May Present With Ophthalmic Manifestations Primary Headache Syndromes Migraine Migraine is the second most common headache syndrome seen in clinical practice. Migraine headache is often characterized as a disabling pain, moderate to severe in intensity, unilateral in location, and pulsatile in quality.
(Migraine headaches are sometimes called vascular headaches. Vascular means having to do with the blood vessels.) These headaches can also suddenly arise in some people when they do not get enough sleep or food. Common triggers of migraine headaches include heat, stress, and lack of sleep or food. Not every headache sufferer is sensitive to these triggers, but virtually all persons with migraine headaches (called migraineurs) have some environmental trigger.
