Hi...have you taken antibiotics in the past few months? May wanna google Clostridium Difficile and check your symptoms. If they match, ask doc to do stool samples X three days, looking for C-Diff and toxins A/B. Best of luck to you.
I suggest that you type in rectal bleeding to google/yahoo etc. You will find numerous sites that describe the main causes of rectal bleeding. The more minor causes include haemorrhoids, anal fissure but, of course, there are more sinister causes too. Probably in your case the cause is more likely to be a recurrence of the haemorrhoids but I suggest that you consult a doctor and get the bleeding checked out. You are entering the age range when cancer can start to occur and, since this possibility always passes through everyone's mind, unless your doctor can 100% assure you that the cause of the bleeding is minor, I suggest that you ask for a colonoscopy which is probably the most conclusive test. Assuming that the outcome is favourable, you will feel reassured and able to dispel doubts that always linger if the diagnosis is "presumptive" rather than "definite".
Good luck
