About A Month Ago, I Got A Cold (runny Nose,

About a month ago, I got a cold (runny nose, sneezing, etc) and a couple days later it settled in my sinuses. It got better, but the sinus congestion reappeared a week ago. Four days ago, I started a really sore throat. Tonight, my throat is better, but my left eye has suddenly become really bloodshot and excreting a thick yellow mucus under the lower eyelid that is very similar to what was being blown out of my nose over the past week. Would the infection from sinuses have gotten into my eye? I've never had thick yellow mucus excreted from my eye before.
