Hi, I Just Got My Wisdom Teeth Removed Three Days

Hi, I just got my wisdom teeth removed three days ago. Since i have been feeling my breathing in my mouth and since yesterday i feel that my sinus is spastic like the feeling you get when you yawn but I cant relax it. Now I am also spitting from the back of my mouth green and clear mucus with black cloudy spots in it. Its that normal it or should I be concerned?
