Re: left dull ache in lower abdomen
I was told exactly the same thing - "thickening of the bowel wall on left upper quadrant" following an ultrasound. I was sent to a general surgeon who did a colonoscopy, and it revealed no problems - well, except for the fact that it showed I have a twisty colon. So she sent me for a cat scan which showed possible slight inflammation on the outside of the colon. So now she is sending me to a gastroenterologist (my 3rd), who I see later today.
What else did they say to you about the cat scan results? Any insight as to causes, treatments, etc.? Please keep me posted.
