Migraines and cluster headaches cause intense, throbbing pain on one side of the head. With a migraine, you may have nausea and vomiting and be sensitive to light and sound. You may also have warning signs, such as flashing lights or loss of parts of your vision, before the pain starts. This is called an aura. Migraines are 3 times more common in females than males. This may be due to hormonal influences. Typical migraines may last for 4 to 72 hours if untreated.
Cluster headaches recur in groups for days, weeks, or months. The pain is centered around or behind one eye. The eye may also become red or teary, or the eyelid may droop. Migraines and cluster headaches can have many triggers.
