My gf is having an ocular migraine. She had one at work yesterday. I had to figure out what she was having by looking up her symptoms she described. Described as a half-moon that starts in the middle as moves to the peripheral before going away, similar to this.
@StephanieResists very similar to what I've had since age 13. It starts like a flash, as if I looked at a lightbulb then looked away. But the flash slowly grows to consume the whole left side of my vision. When it goes out of range the headache begins.
They have become milder and less frequent each year.
@StephanieResists I've spent a lifetime trying to figure out causation... while docs love to say it's this or that or stress, I've never noticed any correlation. Charting them by time of the month may help predict them.
