I am a 49 year - old male, and I have been having pain in the lower left quadrant of my abdomen for 7 months. It is worst in the late night/early morning. My colon seems almost swollen in the morning. It had subsided somewhat during the day, but now it seems to go on for the full 24 hours.
It starts and stays in the lower left, but often it also spreads and hurts all over the lower abdomen.
I have had a colonoscopy, a ct scan, and a lower bowel series, and they are all negative. One doctor said it could be IBS, and another said with no alternating diarrhea or constipation it can't be IBS. I don't have either of those symptoms. They seem to have ruled out diverticulitis, although I have a few diverticula, but my doctor says most people have a few of those. So no one can tell me what it is. It hurts a lot, and makes life difficult.
Is there anything I can do for this? One doctor wants to do a laparoscopy of the abdomen, but I'd rather not get cut open, if I don't have to. Can this be IBS, or should I get some more kinds of tests?
