I have sinus drainage in back of throat and when i clear my throat i spit out green bloody mucus. is this a indication of a sinus infection or cold?

#1 Sinus infection: When mucus is not clear or white, you've probably got infection. The green tells me it's been awhile and blood that it's very badly irritated. See a doctor - I'm cautious w/ antibiotics but this is a green light. Clear it up and discuss ways to prevent recurrence. It's why your face hurts too. You'll feel much better soon - call ASAP.
