The last fifteen minutes have been really strange and scary, for the reason mentioned in the thread title. I'm somewhat allergic to dust, pollen and cat hair, and sometimes I'll start sneezing or having a stuffy nose even though I was perfectly fine minutes before.
Anyway. I had to blow my nose several times with some force to clear things up and stop sneezing, but it was followed with an episode of weird vision troubles.
At first, I noticed a few vague blurry spots in the center of my vision, which didn't seem anymore serious than when you look at a bright light which leaves you seeing a sort of echo of it for a little while. But then I started seeing more spots, which then grew until I could determine that it was actually a ring-shaped region expanding outward which was squiggly/blinking. The weirdest thing is that the center where the first spots were became clear, which is why I stopped panicking and just waited for the circular "wave" to dissipate.
Has anyone ever experienced something like this? I've seen stars plenty of time after intensive sneezing due to allergies, but never something like that. Hopefully it wasn't something like my retina(s) detaching, but who knows? I have a co-worker who suffered that after a head impact, and he saw blinking filaments on his peripheral vision for a very long time.
