The migraine headache is perhaps the best known special type of headache. It is really called the migraine syndrome. By syndrome we mean that a lot of things accompany the headache – all of them bad. Symptoms include dizziness, visual problems, “spots” before the eyes, redness, swelling, tearing of the eyes, muscle contraction, irritability, nausea, vomiting, constipation, or diarrhea. These symptoms often arise before the headache hits. The headache itself may last for a few minutes to a few days, and the severity may range from minor discomfort to immobilizing agony.
