To those who suffer headaches after the aura, not many people realize there is an interesting trick. When you notice the first signs of your aura, try to close your eyes and either go to a dark room or cover your closed eyes with your hand (to make it as dark as possible). In many cases, this will result in a less visible aura and less intense headache.

I read about it on some obscure forum that I'm unable to find right now. Many people commented that it works for them. I tried it, and it definitely lowered the intensity of my ensuing headache. I used to use the time during and right after aura to do the most important things I had to do for the day before the headache took me out of commission for the next 6 hours. But now, on the first sign of aura, I try to close my eyes and go to a dark room. This makes my headaches much more bearable and shorter.

A few people claimed this allows them to stop the aura from spreading (it slowly fades for them as it moves and completely disappears before reaching the edge of their vision) and they don't have the headache at all. I wasn't able to do that, but it makes me wonder if the visual inputs coming from our eyes somehow intensify the wave that is spreading in our brains. And maybe closing our eyes and stopping the inputs from our eyes deprives it of some stimuli that it needs to progress?
