Yes, though I think most of my other symptoms were caused by the inflammation in other parts of my eye. I saw lots of floaters, had blurry vision, and eventually my eyes both went completely bloodshot.

The more common cause of flashing lights is retinal detachment, though... That's considered a medical emergency too.

Please please please see someone you may not care about your health right now but you might well in the future. I have seen you worrying about your vision before and that is what is at stake here...
