Migraine headaches are sometimes preceded by warning symptoms. Triggers include hormonal changes, certain foods and drinks, stress, and exercise.
Migraine headaches can cause throbbing in one particular area that can vary in intensity. Nausea and sensitivity to light and sound are also common symptoms.
Preventive and pain-relieving medications can help manage migraine headaches.
