Migraine is the headache that occurs in the central area of head. Headaches are very commonly noted and you can cure it very simply, but if it is migraine headache then it becomes difficult to treat it. Migraine headaches are very painful than the normal headache. The migraine headaches are caused by the enlargement of the blood vessels in the brain. As these blood vessels enlarge, this leads to the release of the chemicals from nerve fibers around the blood vessels. This causes the pain and the migraine headache is stimulated. This painful headache later on leads to the inflammation and pain. Sometimes even diarrhea is being reported due to the migraines. As per the most of the research studies, women suffer with the migraine more often than men. Even the percentage of the women suffering with migraines is much higher than men.
