What is migraine?
Migraine is a chronic vascular headache which affects approximately 15% of the population. Women are twice as likely to suffer from attacks as men are, and, when there is a history of migraine in the family, this ratio will become even higher.
A migraine is an extended pulsing headache that can last anywhere between four and seventy two hours, typically affecting one side of the head. It is thought that it is the sudden expansion of blood vessels carrying blood to the brain that irritate the surrounding nerve tissues, and so cause a migraine headache.
