question: I have had pain and discomfort in my lower left abdomen for about a week now. It started as a bulging discomfort now more of a shooting pain. I went to the ER and they took blood, urine sample, and did a CT scan. CT scan was normal and the doctor said there was some bacteria in my urine. I went to a GI and he spent all of 5 minutes with me and scheduled a colonoscopy. Prior to this I took some Pepto Bismol and Kaopectate to control diarrhea. Im starting to wonder if maybe its an infection since all tests have come back clean? Any ideas?
