Sinuses full of green and yellow phlegm?

on tuesday i woke up with a runny nose and fever and i started feeling more and more shitty as the day went on. by 3ish i had a mild cough, nothing too bad. i also ended up having bad diarrhea but i blame that on taco bells new shrimp tacos haha. i haven't had diarrhea or taco bell since. anyways, since waking up on wednesday my sinuses have been full of greenish-yellow (sometimes more green, sometimes more yellow, and sometimes with blood in it) phlegm. my nose fills back up with it faster than i can blow it. i havent had a cough, fever, or runny nose since tuesday, just this annoying phelgm and fatigue. i usually dont get sick, whats wrong with me?
