Last night I had a Visual Migraine that was significantly worse than the previous ones. It started in the usual manner (flickering lights in my central vision and an inability to read text on a computer screen in a font that is normally quite readable) but then developed a new feature. Grey clouds appeared in the periphery of my vision which left me with only central vision which was obscured by flickering lights.
About an hour later it was gone. I’m glad that I don’t drive much, such limited vision is enough to allow me to use public transport without serious problems (although crossing a road could be interesting). Spending an hour in a parked car at the side of a road waiting for a migraine to go away is not something I’m looking forward to.
