Migraine Headache

If the serotonin levels are high, then blood vessels constrict and When serotonin levels fall, then blood vessels dilate. So this swelling may cause pain or other problems. The evolution of a migraine headache has four distinct phases such as Normal, Vasoconstriction, Parenchymal artery dilation, Vasodilation (headache).
