Blood on surface of my stool

[jam34983]

Hello, I had rectal bleeding about 4 years ago which turned out to be a hemorrhoid, The doctor clipped it and about a week later I noticed bleeding again. Called the doctor and I schedule a appointment but the appointment was two weeks away. So every day until my appointment I stuck my finger in to my rectum I know disgusted, but I noticed a bulge get The bulge got smaller every day until my appointment The doctor looked inside my rectum couldn't find anything wrong so he scheduled a colonoscopy. I have a cleared colonoscopy no polyps or anything fast forward to now four years later I noticed right sweat blood on the surface of my stool. It's all in one place about the size of a dime, my stool has always been hard and large I think my whole life. Sometime it's difficult to push them out sometimes, and it hurts like hell sometimes also every time I have a bowel movement about 30 to 45 minutes later my rectum would Itch like crazy, don't know if I have cuts or what but it does it like almost all the time. So I'm thinking should I get a doctor to do a colonoscopy again to ease my mind. What do you think ? Am I being paranoid. Ps I'm only 33 years old no family history of colon problems.
