Migraine headaches are a specific type of headache that often results in recurring episodes for those that experience them. Migraines are different from other headaches because they also often occur with symptoms such as acute nausea, vomiting, or sensitivity to light. Those that experience migraines may have warning symptoms, called an aura, before the actual headache begins. Most people, however, do not have such warning symptoms and endure what is often a debilitating headache.
