Colonoscopy came back clear but ct scan showed inflammation

Male 24 I have had right side stomach pains for 2/3 years. Been going to the doctors on and off and kept getting told I had ibs, anyways there finally give me a colonoscopy in October 2017 it came back clear, there didn’t take a biopsy as he felt like there was no need. Any how still getting the pain I had an ultersound and that came back clear. There then sent me for a ct scan which the doctors have said that my right colon looks inflamed. I’m a bit confused as the colonoscopy came back clear and i have had stool tests in the last year which showed no signs off inflammation, could there have got it wrong and if not would that mean I have colitus. I’m just a bit worried as I can’t get to see the doctor until next Thursday. When I got the letter back from the doctor for the ct scan it said call for an non urgent phone consultation. Thanks  

Hi Jamie, your symptoms sound very similar to mine.. Ive had right sided pain on and off for years.. I have had blood tests and scans that show everything seems to be ok.. but the pain remains.. I found the prospect of putting myself through a colonoscopy when the results when showing things were ok quite difficult, but I recently opted to do CT colonography, where air is introduced into the bowel and then scanned... I havnt had the results yet, but its interesting to hear you have had inflammation diagnosed.. Be intresting to see what adv ice follows your results.. Lesley
