It's very rare. I was a migraine sufferer, but this is how that time it was different:

- I was under severe stress at work - I woke up with aura, realised it when looking at the mirror, I had only one eye - visual symptoms (aura) didn't go away after 1 hour. That's the limit where you MUST seek medical advice - having "a migraine" that day raised my stress level... because work... - symptoms persisted... and after getting better over a year, what was left became permanent (blind spot where the migraine started in my field of vision)

DO NOT take triptans during the aura. DO NOT take any vasoconstrictors during aura, since it's a phase where blood flow is restricted. That could have caused my stroke.

When a migraine hits, I take aspirin, stop all stressors, ALL stressors, try to calm down (I've used anxiolytics occasionally), breathe and rest. I'm often off for 2 days. It happens about once a year.

Again, migrainous infarcts are VERY rare. You'll be fine, just let the aura pass, and know to seek medical attention if it doesn't.
