Ive had blood on my stool infrequently but for many months assuming hemerrhoids. For a couple of weeks Ive had inconsistant bowels. Some dark but not black. Some streaked w blood(least consitant). The most consistant symptoms would be narrow stools in between regular bowels, as well as pain and pressure in the rectum area. I took stool softeners which helped a lot w the pain. The narrow bowels are daily and making me nervous. My research tells me that if I have cancer the symptoms show late stages. If I knew of other diagnoses I might be less concerned. Im only 24 years old. White male. 6' 220lbs. Anything can help please!!?!?!?........
