I have extremely bad pain in abdoman after a bm, have not been able to eat for 6 days, stool sample, blood work and catscan all negative! help?

Relax: If your work up was negative, most of the bad stuff is ruled out (like cancer, liver failure, or dead intestine). Also, most of the stuff that's easily fixed is eliminated too, like ulcer, infection, or hernia. Something may be going on, but it might take time to figure it out. Eat what you can, like soups and light meals. Unless you've lost weight (10 lbs or more) it's ok to skip a few meals.
