I just had a CT scan and have been diagnosed with a "mild wall thickening of the ascending colon and hepatic flexure" suggesting a colitis. Endoscopy may be helpful to further evaluate. Everything that I have been reading says that the most common symptoms are stomach cramping, diarrhea (even bloody diarrhea), frequent loose stools, fever chills, nausea, weight loss, and tiredness. Out of all these I only have lower abdominal pain and tiredness. I have never in my life had regular bowels movement but now when I have the urge it is accompanied with lower abdominal pain and I will go to the bathroom and it is sometimes still a strain or only a little comes out and the pain still remains. TAnd his has been going on now since right before Christmas '08. I am taking two medicines and my doctor is going to refer me to a gastrologist.
My question is, how serious is this? And should I have reason to be nervous?
