If you aren't aware, an ocular migraine is a migraine in your retina(s). It shares many of the same symptoms as a typical migraine, but your sight also goes all fucked up. Like, seeing glowy flickering zig zags and/or blindspots. Weird shit like that.
You know how if you stare at a bright light and it leaves an afterglow on your retina that fucks with your sight for a few minutes and goes away? It was like that, but it happened spontaneously, got more intense, and included migraine symptoms.
