I was sent for a colonoscopy as have been having bad pains on lower right side and upper left side since having a bad case of diarohea about 3 years ago, along with cramping and bloating and urgency to go to the toilet especially first thing in the morning, some bleeding, but not often so I had put this down to possibly piles, also raised crp levels in blood tests, gp suspected diverticulitis so gave me antibiotics which helped a bit. Colonoscopy also showed extensive diverticulitis. If it is crohns this might make sense as have issues with my skin and also issues with the white of my eye randomly bubbling (the only way I can describe it lol)
