Hi, Welcome to Healthcaremagic.com. I had gone through your question I can understand your concern about your bleeding. As per your history it is suggestive of a chronic ulcer in your rectal or colon area, it can also be the hemorrhoids (Piles) too. Yes you need to have an examination of your rectal area like colonoscopy or sigmoidoscopy. The fresh blood in stools can be some times dangerous too. Early examination is good for some diseases and late can lead to bad prognosis. Hope my answer will help you and visit us back if you have any other questions to ask.
