Is it a cold?!

Is it a cold?

For a week now i've had, what i thought was a cold but yesterday my sister told me it might be something else. My symptoms are: stuffy nose, greenish mucus, constant clearing of throat (yet no coughing). Since I've been feeling really well (no headackes or anything) I don't think i'm gonna go see a doctor. But i'd still like to know what it is i have??

oh and a few days ago i was coughing and a little bit of blood came out of my mouth =S

thanks for the help!

If you you have frequent discharge og greenish mucus or phlegm you should go under antibiotic therapy.
But your condition may be from some sort of allergy. Just try some antihistamines, inhaling eucalyptus or thyme steam, and avoid frozen or spicy food.
