A migraine is a type of headache in which pain is often intense
and increases to the point of becoming disabling. The
International Headache Society has developed guidelines that
describe a migraine separately from Tension, Cluster or other
type.
A migraine
headache refers
to a headache that has recurred at least five times, lasts
between 4 and 72 hours if untreated, is often unilateral,
pulsating, moderate
to severe in
pain and is aggravated by routine physical activity. During the
headache nausea or vomiting, light or sound hypersensitivity may
occur. The headache may occur before the menstrual time or may be
heralded by a warning before
the pain. |
