Brighter Than a Cloud
How to describe a scintillating scotoma? It’s one of the most common symptoms of a migraine, but unless you’ve had one, it sounds unreal. A scintillating scotoma is like a barbed ripple in the pool of sight. It’s a skeletal Magic Eye raised up from the flatness of the world. It’s a glare on the tarmac as you drive West at sunset on a rain-slick freeway—only when you turn your head, it’s still there, so you have to pull over, close your eyes, and wait out the slow-motion firework working its way across your brain.
