Question: I had a colonoscopy, and a few hours later, passed a few small pieces of tissue with blood. Have some pain in lower left quadrant, but he took 4 small polyps (6-8 mm) in sigmoid and there was congested mucosa in that area as well. The pain is improving, and I have no fever anymore (had one yesterday, but I am also sick, so I really think it was from that...my husband had a fever when he had this cold). My doctor is on vacation until next week and the on-call PA is recommending a CT. They won't consider MRI or X-ray. I am trying to avoid CT imaging, if at all possible because I've had 3 CTs in the past 6 months due to pelvic surgeries (hysterectomy, sling, and sling removal due to complications). My pelvis was inflamed following the colonoscopy too, but I'm sure that was the pelvic floor acting up again after the poking and prodding from the scope. The pain is very localized to one spot in the sigmoid colon (probably where the polyps were removed). I also had c-diff after all of the antibiotics for the pelvic problems, so am still on the course of vanco (although symptoms have improved and no colitis wa found during colonoscopy), so really want to avoid contrast agent due to nephrotoxic risks. Do you think I need to proceed with CT right away, or could I wait a few days to see if pain continues to imrove? They are leaving it up to me, and I'd like some input.
