Migraines are just headaches plus other symptoms.
No, this is wrong because headaches are caused by your blood vessals becoming smaller. Blood vessal are sensitive to pain so when you have a headache the pain you experience is from the pain receptors on your blood vessals. The only time you have pressure on your cerebral fluid is when you have a brain tumor. I think I might have a brain tumor, however my doctor is useless, plus constant headaches for a year you get use to it. Weird I have hyper sensitivity to sound, but not light.
http://en.wikipedia.org/wiki/Migraine I see science was not your strong subject. More off a art person Howietzer.
P.S. About four or five months ago, we had a cancer research person who said about a person who had brain cancer, she bascially described what I have now:blue:[/b]
