Hi - I have been having low abdominal pain since last november, it keeps me from sleeping and some days I can stand/ sit it can be so painful. I also have joint pain and I tired all the time. I have blood in my diarreah and also have bloody mucus, no pain from the bleeding like I have had before with anal fissures etc, I was sent for a flexible sigmoidoscopy and it cam back as normal.. so they have said it is ibs? All the sites and info I have read say that bleeding is not part of IBS.. Im confused and fustrated - any one got any thoughs or similar experiences I would appreciate any advice.
