Hi there, I have for the last 6 months had rectal bleeding, mucus discharge, bloody bowel movements and it feels like i need to go all the time, I have had a FOBT and it came back as 63ug/g it should only be 50.

I am 26, ex smoker with no other health issues, My inital exam from my own doctor ruled our hemmroids and anal fissure, I have chronic pain in my right side when i need to move my bowels and my lower back aches sometimes too.

What can I expect? What are my possible diagnosis?
