Hi, i think something is really wrong with me, hopefully i'm just being paranoid. i've had cold and flu symptoms, and if i blow my nose, most of is blood. is this something serious?

Possibly : Bleeding can occur when having cold but usually the bleeding is mild. If you have excessive bleeding, then you need further testing for bleeding disorder, nasal problems or even rarely cancer (e.g. Leukemia). I recommend that you get checked and get blood work done soon..

NOT BAD: It is common, blowing too often small vessels break and bleed . Careful blowing nose and use nasal saline solution. If continues see a physician.
