Consistant pain lower right abdomen

Hello I have had severe IBS for over 50 years. Had gallbladder surgery almost 2 years ago. Since the surgery I experienced all the most horrifying pain and sickness imaginable from extreme gastritis, hiatus hernia, gerd, nausea, yellow stools, horrible multiple food intolerances and unimaginable bloating. My past reliable IBS symptoms have completely changed with the onset of post gallbladder surgery syndrome. While the first symptoms produced all the above side effects with upper abdominal bloating it recently changed to lower abdominal bloating with intermittent bladder pressure and more consistent lower right side pain that sometimes spreads and most always stays in the same area (about 3 inches to the right and 1 inch lower than my belly button. My question: has anyone experienced a fairly stationary right lower side pain with IBS or after having gb surgery? Had many negative tests but a colonoscopy which is advised but would be life threatening due to moderate diverticulosis etc. Any input would be most appreciated.

Perhaps it would be better not to have a conventional colonoscopy given your risk Ask your doctor if it is really necessary. If it is, ask for a CT colonoscopy instead

I had a CT scan done and was normal. What is a CT colonoscopy in comparison? Must you take full prep for this as is used in regular colonoscopy?

Look up bile acid malapsurption. I got it after having my gallbladder removed. Took me a few years to get diagnosed. Once on medication it was under control.

A CT colonoscopy takes pictures of your bowel and is not so invasive as a standard colonoscopy. It doesn’t involve biopsies. It doesn’t require sedation but you will need bowel prep so they can get a clear picture of your colon.
