My husband has had blood with BMs for last 24 hours. Some is bright red and some is dark. He has a sense of urgency when he goes and it is somewhat explosive. It appears stringy and smells foul. He
has no pain associated with it. What do you think? He is 69 yrs old, 5'4", 200 lbs, has history of CAD with dbl bypass and aortic valve replacement in 4/2010. hemorrhoids,diverticulosis,polyps.
