I get migraines. I didn’t know that’s what they were, I thought I was having a stroke. Mine have very little pain, no nausea and extreme visual disturbance. The outer edges of my visual field start to ripple and then flash, and then my central vision fades in spots, while my brain tries to make up for it by collapsing the information around the blind spot together. This results in things like faces without noses, and headless cats. Bad scene.
I hope they stay this way and never get painful. They’re like an acid trip without the high. Entirely unenjoyable, but tolerable. They last about 20 minutes to an hour, and can be triggered by reading light text on a dark background. Also that vibrant fluorescent green that was a hot color a few years ago.
Anyway I feel one coming on, so it’s time to turn off the screen.
Ugh. I have a relative with a precipitating aura like that.
I hope you’re feeling better!
Much better, thanks! It ebbed into a mild headache which hung around until morning, but reading your comment made me realize it’s gone now too!
