Like most things there are many levels not just one (or cranked to 11 in your cases).
I'm a bloke and i get them occasionally. I dont get them bad but the visual pulsing with checker board squiggles in the visual periphery and the dull throbbing headache and nausea that can last from 5 minutes to several hours are so obviously different to a normal headache.
So if you are saying that because i am not incapacitated for several days it's not a migraine then you are wrong. Just sayin'.
