Migraines are intense headaches that can cause severe pain, usually on one side of the head. People who experience migraines may also have other symptoms, such as nausea, vomiting, sensitivity to light or sound, and blurred vision. Migraines can last for a few hours or even several days, making it challenging for individuals to carry out their daily activities.

The exact cause of migraines is still being studied, but scientists think it has to do with changes in brain activity and blood flow. Certain triggers, like stress, certain foods, hormonal changes, or lack of sleep, can make someone more likely to have a migraine.

If someone has migraines, they may need to see a doctor who can help manage the symptoms. Doctors can prescribe medicines to relieve pain during a migraine attack or recommend preventive measures to reduce the frequency and severity of migraines.
