My first GI would not diagnose me, even though I had ulcers in my TI and inflammation in my cecum and ascending colon. My biopsies also showed cryptitis.
When I went to my current GI for a second opinion, he thought Crohn's just based on what my colonoscopy said. He ordered the pill cam to see if I had small bowel involvement as well. The pill cam found inflammation throughout my entire small bowel and the I was "officially" diagnosed with Crohn's. I had the symptoms of Crohn's about a year before my official diagnosis (Diarrhea, eye inflammation, mouth sores).
Before I was diagnosed, I believe I was in a form of denial, too. I knew something was wrong, but I didn't want it to be Crohn's. At the same time though, I was frustrated NOT knowing for sure what was wrong.
I wish you the very best and hope you get answers soon.
