question: I'm 28 5'10 and 195lbs. I am feeling a hard lump in my lower left side. Two days ago I had a colonoscopy by a new GI because I had been having bad pain and fevers with runny bowels  which is common for me because of a history of diverticultis 5 years now. The weird thing is my new GI did the colonoscopy and told me that he didnt see any diverticulitis  as he brushed me off and said its a spastic colon. Which I also knew I had along with the diverticulitis and peptic ulcers occassionally. But I'm scared right now because I am feeling this large hard limp in my lower left side that is causing me to cry in pain and is producing watery diaherra still 2 days after having this colonoscopy. What should I do seriously? And yes colon cancers run in my family and have taken two of my close blood relatives. 5yrs of pain is long enough and now with a large lump I just want to get to the bottom of it.
