Migraine headaches are a type of headache that can cause intense throbbing or pulsing pain, usually on one side of the head. They can last from 4 to 72 hours and are often accompanied by other symptoms such as nausea, vomiting, sensitivity to light and sound, and blurred vision. Migraine headaches can be triggered by certain foods, stress, hormonal changes, and other factors. Treatment for migraine headaches typically includes medications, lifestyle changes, and relaxation techniques.
