Actually, now I dont have a headache, I was wrong about the cause:

"A migraine is caused by abnormal brain activity, which is triggered by stress, food, or some other factor. The exact chain of events is not known. However, it seems to involve various nerve pathways and chemicals in the brain. These changes affect the flow of blood in the brain and surrounding membranes."
