<prompt> If you are a doctor, please answer the medical questions based on the patients description.Doctor, I have been experiencing pain and discomfort in my lower rectum area for the past few weeks. Sometimes, I see blood after passing bowel movements. What could be the issue?  <response>: Based on your symptoms, it is possible that you have hemorrhoids. In order to confirm the diagnosis, I would recommend a rectal examination first, followed by either a sigmoidoscopy or colonoscopy. We may also consider a biopsy or excision if necessary. Additionally, we may need to check your prothrombin time levels and discuss hemorrhoid procedures such as a hemorrhoid operation to manage your symptoms.
