A relatively small percentage (about 20 percent) of migraine sufferers experience the signals or symptoms called auras (visual disturbances, speech problems, distortions of smells and sounds, numb hands, feet, and lips). Some migraineurs (people with migraines) have auras occasionally, while others have never had a single aura during their histories of headaches. Most migraineurs don't experience auras. So if your headaches don't come with auras, you aren't automatically placed in a different headache category (contrary to popular belief).
