A migraine is a type of severe headache that can cause intense throbbing or pulsing in one area of the head. Migraines are commonly accompanied by nausea, vomiting and increased sensitivity to light and sound. A migraine attack can last for hours to days. Some migraines are preceeded by sensory warning symptoms, also known as auras. Auras may appear as flashes of light, blind spots, black lines in your field of vision, or tingling in the arm or leg. Women are three times more likely to experience migraines than men. Common migraine triggers include stress, changes in sleep patterns, dehydration, and strenuous exercise.
