I have suffered with continuous diarrhoea for 5 months where I have taken Imodium and then it starts again. I have a small amount of blood on the toilet paper. So yesterday I went to see my gp who did a full examination and asked I do a stool sample and said I would recieve a second kit in the post. I don't have any pain just the need to go to the toilet but I'm so worried it could be biwel cancer.
