Had an aura migraine earlier. Flashing zig zags gradually covering field of vision over 45 minutes. Not had one for about 4 years. Started taking Multivitamins a couple of days ago...coincidence?
I have these from time to time and there is no discernible reason for why I have them. They just seem to come unbidden, so I can't say if multivitamins have any impact, but I would think not to be honest.
I suffer these too and completely block my vision in one eye, had two this week yet can be a few weeks between. They disappear when the zig zag ring joins up into a circle. Very weird yet never found out why.
Herelam ...weird aren't they. I also get a numb spot on my body; sometimes foot but this one was with a tingling hand and lip. Aura is Like looking through a kaleidoscope. I never get a headache as such though just a heavy head feeling.
DENZIL, I don't get any feelings at all, just a zig zag that starts of tiny and gets bigger and bigger till it disappears and is always multicoloured. When I first had one many years ago, I was scared, but went online and saw that they are quite common and even my optician couldn't give a reasonable explanation for them.
Sometimes they are triggered by specific foods...for me,it seems to be wheat combined with stress and erratic eating. Might be good to keep a food/mood diary.
Magnesium was recommended to me several years ago...I take a supplement and that seems to help.
