Mine started out with eye inflammation that would not go away. I DID have diarrhea and gas, but I figured it was just my stomach. Anyhow, after having the eye inflammation for about 6 months, I went to see my Internist and she instantly thought Crohn's. Getting diagnosed was another issue.
The first GI would not diagnose it, although I had inflammation in my ascending colon, cecum, and inflammation in my TI and ulcers. I also had extraintestinal symptoms as well that the first GI pretty much blew off.
I had the SBFT which showed absolutely nothing. Then I had the pill cam done which showed inflammation throughout my entire small bowel, and that got me the official diagnosis.
My bloodwork has always been normal except for the high WBC count probably caused by taking prednisone. My serology 7 was also normal.
I wasn't in awful pain at the time I had any of the tests, come to think of it. Honestly, my bowel symptoms are minor compared to my extraintestinal symptoms, which is weird, but I guess that is just how I flare. Don't get me wrong, sometimes my stomach about kills me, but the arthritis and the scleritis (especially the scleritis) are just awful at times.
I guess my point is even though my stomach was not feeling terrible at the time, I still had inflammation show up on both my colonoscopy and pill cam.
Best of luck to you and keep us posted.
