Hello, I noticed one night last week that my left eye felt bruised, the eyeball itself and when I got home and was able to look in the mirror I noticed it was all red and bloodshot, so I took out my contacts and put a warm compress on it, thinking it might be pink eye, it was pretty bad that it lasted through half of the next day, I finally put my contact back in that day mid day and by night it was sore and red again, and it has been like this every evening, some nights less painful, some nights real painful and bloodshot, tonight it feels real bad again. What might this be?
