I get an aura where I lose part of my field of vision. Across the blank space is a jagged thing. One time I googled "migraine art" and saw several renditions that were exactly like mine. I told my dad that, because he gets the aura too, and he picked his aura out too-- his is different than mine. Isn't that fascinating!
Usually I also get a splitting headache but not always, and anyway it is the vision loss that is scary.
One time when I had one of these migraines I couldn't remember some of my words. I was trying to say I needed to heat up my lunch and all I could come up with was "feed". It sounds a little like heat and it was to do with food. But the word "heat" just wasn't quite there. I did go to a doctor. They said it was a mild ischemia-- a mini stroke. They didn't seem too worried about it.
My biggest concern was that my grandmother died of a brain aneurysm but it turns out there is no link. In fact it's beneficial to have a history of migraines because if I ever do get an aneurysm I'll know that it's not a migraine, which is what it is commonly mis-diagnosed as.
I don't think you need to feel too worried, but it is important to get it documented in your health history. So I also advise seeing a doctor, for that purpose. Just don't let them bully you into taking medications that you don't need.
