Three weeks ago I suddenly had diarrhea. It continued for a week as regular diarrhea and then it stared to become bloody. It looks like sawdust in the toilet that sinks to the bottom of the bowel. and collects in a pile like dirt. Usually at the end of the movement there is red blood and blood on the toilet paper. Its been the same for 2 weeks . Stool sample came and blood work normal except wbc elevated in stool. Dr prescribed antibiotic Augmentin. Which haven't changed anything. Im going to get a ct at the end of the week. I have no pain, I don't feel tired I don't have a history of gi problems im 35 years old. The only thing that made me start thinking I might have IBD is I have developed some canker sores on the side of my tongue and cheek . Does this sound like IBD or am I reading to far into it.
