Types And Symptoms Of Migraine Headaches
Wednesday, September 10th, 2008
Migraines headaches are throbbing headaches that involve the brain’s blood vessels. Pain is felt when these blood vessels dilate or contract in an excessive manner. Studies have shown that the dilation and contraction of these blood vessels are influenced by a chemical in our body called serotonin. A high level of serotonin in our blood will cause our blood vessels to contract or shrink. Conversely when the level is low, it will cause our blood vessels to dilate or expand. Different individuals react differently to these dilation and expansion. Keep in mind that any migraine will be as unique as the person suffering from it and that these migraine headaches symptoms will vary from one individual to the next.
