Migraine

Migraine is a neurological disorder often described as intense pulsing or throbbing pain in one area of the head. Typically the headache is unilateral (affecting one half of the head) and pulsating in nature, lasting from 2 to 72 hours.

Migraines are believed to be due to a mixture of environmental and genetic factors . Migraines typically present with self-limited, recurrent severe headache associated with autonomic symptoms.
