A migraine headache is a potentially debilitating attack that often causes severe pain that comes in throbbing or pulsating waves on one side of your head. The headache can be further irritated by sensitivity to light and sound. It is not uncommon for the migraine sufferer to experience nausea and/or vomiting as well.
Not all headaches represent migraines, and migraine is not the only condition that can cause severe and debilitating headaches. For example, cluster headaches are very severe headaches that affect one side of the head in a recurrent manner (occurring in a cluster over time). The pain is sometimes described as drilling, and can be worse than migraine pain in some cases. Cluster headaches are less common than migraine.
