About 2 months ago I developed a very itch rectum at nights and at the same time noticed bright red blood in my stools, went to the doctors and was prescribed haemorrhoid suppositories, which seemed to clear it up,but a fortnight after the symptoms returned, The Dr referred me for a Sigmoidoscopy and they found Polyps which they biopsed (the Dr said they didn`t look sinister) but said I had patchy inflammation of the Sigmoid and need a colonoscopy. The thing is I`ve read all the symptoms of Crohns disease, IBD and Bowel Cancer and have none of them. is there anything else that could cause this inflammation?
