They did a small bowel follow through and found a stricture. I was having severe pain because food was not going through properly. My gi also went by my white blood cell count which was high, my crp which was high, and I had alot of symptoms: night sweats, fevers, joints that would swell for no reason, severe diahrrea, stomach pain, weight loss, anemia, etc. I had a bowel resection and when they went in, they found other skipped spots along my small intestine where inflammation was in between healthy areas so they had to take out a little more than they expected. I hope you can get a diagnosis and start feeling better.
