Migraine is commonest type of headache that needs a visit to a doctor. It is also the commonest cause of severe headache. Migraine headaches are different from other types of headaches and can be diagnosed by its characteristics. Family history of migraines, age when the first attack occurred, and frequency and duration of headaches will also help to determine whether an individual is suffering from migraines or not.
