My husband has been having this problem for three years or more and I am very concerned about him. He has blood in his stool on a weekly basis. It is bright red and lots of it. He has been to the doctor four different times about this, because it's so scary. The doctor has examined him and he has had a colonoscopy, and everything seems to be normal. The doc says the bleeding comes from hemmorhiods and fishers, Can they really cause that much bleeding? I just don't know if we should go to a different doctor or maybe it is normal to some extent.
