My niece gets bad ones {no TOS} she gets nausea, tunnel vision, auras.

I had an optical migraine once at work- was seeing shooting sparks, stars, like fireworks and then things started spinning around and nausea after the visual sx stopped. I made it home but I was wiped out for the rest of the day. I did go to eye dr to get it checked - he was the one to dx was it was.
