Hmm. Every once in a while, when I move my eye, I get a sharp, stabbing pain in the corner of my eye, right where it "meets" my nose. I can't duplicate it (not that I want to) nor can I really figure out what exactly I'm doing when it happens--in other words, if I'm glancing right or left or whatever. I have an eye appointment in a few weeks. Not seeing any sparkles or anything.
