I'll get to the point, the pit is always better qualified than doctors so I'm coming to you guys. What does it mean when I've been coughing heaps for 12 days, vomiting a bit, diarrhea today with a greeney look and blood in my stool?

Am i boned?

FYI, i have been to the doctor, he said it was a sinus infection and gave me some pills. They've done nothing and I'm worse now, so I'm seeing him again on Tuesday.

What should i do pit?
For those who care.
