I used to get them on a weekly basis. My neurologist suggested I go to an ophthalmologist after noticing that the pupil in my right eye is smaller than the one in my right. There, I was diagnosed with Horner's syndrome and mild astigmatism. It was suggested that I try corrective lenses before medication. I did just that, and now I only get them two to three times a year. My usual symptoms are vertigo/dizziness, nausea, phono- and photosensitivity, and ocular twitching. I sometimes get auras and floaters, but not always.
There are two that I had that really stand out to me, though. The first one is one that lasted for five days straight. I was still in high school at the time, and missed the whole week of classes. Just a dull, dizzying, debilitating pain that wouldn't let me open my eyes or even listen to ambient sounds in my house. I barely crawled out of bed to go to the bathroom or eat.
I'm not quite sure if the second one was a migraine or not. The pain was familiar to that of a migraine, as were my usual symptoms. But the pain was so much more intense than a usual migraine, that I can't even accurately describe it. The only way I can describe it is it was like having my head run over by a lead bus the size of Jupiter. My only thought was that I didn't want to live anymore. I was driving home from university when it struck, and I legitimately thought about crashing my car into a lake or a tree just so I could end it. I ended up pulling off to the side of the road. I called my mom and told her that I may have to call an ambulance, closed my eyes, and took a short nap. I then drove the rest of the way home. When I got inside, I straight-up fell to the floor and passed out because of the amount of pain I was in. I ended up sleeping for about 16 hours.
