Hello. I had a ct scan done. the ct scan showed distal small intestine inflamed and there a mesenteric lymph node that measures 1.5X1.4cm. Along with several other swollen lymph nodes. The problem is that the stool sample for inflammation was negative. I have a colonoscopy in the am. The question is, is this Crohns? Infection? Or nothing? I am on a diet of just rice. Thats all I can eat. Anything else causes intense pain and excessive use of the bathroom.
