My GI has never given me a colonoscopy, even when I was hospitalized, and has never suggested I have one. Which seems odd to me. Maybe because I'm 31?
I've only ever had a sigmoidoscopy and abdominal ultrasound. For all we know I could have Crohn's. Sigh.
You need a colonoscopy and a new GI (not necessarily in that order). If you had crohns it might have shown on the abdominal ultrasound. A good GI ought to have done a colonoscopy for the initial diagnosis at least.... I've had a colonoscopy every time the doctor needed the information to determine my next treatment step (especially since symptoms are often not always correlated with the extent or
location of the inflammation).
