Last week I had a hectic schedule and lost a good amount of sleep. At the end of the week I got a migraine two days in a row. I usually get migraines from lack of sleep, but I haven't had concurrent ones for a few years now. Since the pain has gone away, I am still seeing a somewhat bright spot in my left eye. It is fairly round, and doesn't impair my vision too much, but when I blink I can see it, as if I had been looking at the sun for a little too long. It has lessened in terms of brightness over the past few days, but occasionally it behaves a bit like the aura I see before migraines, but never progresses into a full out pre-migraine aura like I usually get. It's been about 3 days now and it still hasn't gone away. Should I be worried about this? Thanks.
