My right eye suddenly began to feel irritated, like I had something in it. I did rub it pretty hard, and then when I went to look at it, it's very red (probably due to the rubbing) and the part of the eye next to the cornea looks swollen - when I look to the side towards my nose, I can see it bunching up against my cornea. I've never seen my eye do that before. I can see fine out of it, but it still feels like there's something in it and it's tearing up a lot. Will it subside on its own?
