Question: Hello, I'm a 30yo female, and I had very dark, loose stools that looked almost a dark green/blackish color after having a colo/endo done approx. 2 days ago for ileus of undetermined cause. Nothing was found on colo but endo showed an esophageal polyp and gastritis, of which biopsies were taken. I have been having all-over abdominal pain since and been feeling faint and sleepy. I have not been able to have a BM since this morning. The doctor prescribed Bentyl and Librax, which I haven't been able to get to the pharmacy for (I can't hardly walk, much less drive right now). Could it be an upper GI bleed (family history of abdominal perfs), or would it be more profuse and more black in the stool? There is no fever, but BP is low at 97/60 with HR of 100. Nausea and vomiting are present but not extreme. Would it be stupid of me to go to the Emergency Room, or wait until my primary gets back on Monday?

Ok, thank you. That eases my mind somewhat.
