Migraine
Most migraines cause a headache and nausea and might make the person dizzy or very sensitive to bright lights or loud noises. They may see funny patterns, have blurry vision, or may not be able to see at all. Other senses can change before or during a migraine, and the person may sense funny smells or tastes. Migraines can last a long time. Most migraines only last about 4 hours. Some can last up to 72 hours.
