A migraine is more than a bad headache. It is an attack that is usually made up of many symptoms.
Severe migraines knock sufferers completely off their feet.
Researchers think that a migraine begins with electrical and chemical disturbances in the brain. These lead to inflammation of blood vessels in the head, resulting in pain. Migraine headaches usually begin as a dull ache, often in only one side of the head. The pain gets worse and turns into pounding or throbbing. Regular pain medications do little good, and movement makes the pain worse.
