Migraine headaches

In this type of headache, symptoms other than pain occur as part of the headache. Nausea and vomiting, lightheadedness, sensitivity to light (photophobia), and other visual symptoms typically occur with migraines. Migraines also have distinct phases. Not all people have each phase, however. The phases of a migraine headache may include:

• Premonition or prodromal phase. A change in mood or behavior may occur hours or days before the headache.
• Aura phase. A group of visual, sensory, or motor symptoms can precede the headache. Examples include vision changes, hallucinations, numbness, changes in speech, and muscle weakness.
• Headache phase. Period during the actual headache with throbbing pain on one or both sides of the head. Sensitivity to light and motion are common, as are depression, fatigue, and anxiety.
• Resolution phase. Pain lessens during this phase, but may be replaced with fatigue, irritability, and trouble concentrating. Some people feel refreshed after an attack, others do not.
