No stool only blood & mucus with discomfort abdomen
Um..it is hard to tell what it can be in your case. A lot of things, actually. From hemorrhoids to a rectal ulcer, to cancer...It could be anything.
Did you make an appointment with your doctor? You should.
The treatments are different and they can range from stool softeners, high fiber diet program, some sitz baths, laxatives, etc.
I really do believe that because of your situation and condition you will need some stool softeners, but I am not so sure. That is why I do recommend you to visit your doctor as soon as you can to see what this all fuss about rectal bleeding is about.
