Have you ever had a stye in your eye or a chalazion before? I've dealt with two chalazions on my right eye recently, the first one wouldn't go away so I got it surgically removed. This latest one is slowly going away on it's own thankfully. Chalazions appear on your upper lid and actually don't hurt they're just super annoying to deal with. However, styes are usually on your lower eye lid and often hurt. I've never had one of those before thankfully.
