Any idea why an eye would start watering and keep doing so for days? It's not so bad that it looks like I'm crying, but I need to dab my eyes with a tissue every couple of minutes. When I yawn it's horrible! My eyes are not any more red than they usually are. I have noticed some random itching, but not constant. It's been going on since Sunday. What could it be?
ETA - it's really only my left eye that's a problem, not both.
