The motivation for this particular article was my wife. She is one of many in this country who suffer from migraine headaches. While casually carrying on a conversation one evening, she asked my why particular things, like vomiting, occurred during her migraine attacks. I jotted down a list of things she said she had experienced before and during the full on migraine and researched what modern medicine says are the reasons such things happen.
The article will not tell you what symptoms are (unlike many articles), it will explain why stuff happens to you before an attack. Read http://john000.hubpages.com/hub/Migraine-SymptomsSound-Light-Smell-Numbness-Pounding-Aura-Vomiting-and-MSG
