I have a sore on my stomach and I'm

Yeah see a doctor

sounds like Staph see a doctor

You def. need to go see a doctor. It could be a staph infection which in some cases, can be fatal. I had one about a year ago. It was like an enormous spider bite that hurt immensly with the slightest touch. Had to put a hot compress on it every once in a while. It came to a head and i had to drain all the puss out of it. Exactly like a giang pimple. like the size of a half dollar. Damn, i can elaborate.

what does the sore look like? how long have you had it?

call in sick, go to the doctor - life is too precious to sit and wait

A sore -on- or -in-? I ask because I had the same thing when I was diagnosed with appendicitis. Don't wait. If it bursts you'll really be in trouble.
