I was thinking I had the same thing, but after a CT scan and then two MRIs (one full body, another pelvis) showed nothing but inflammation. A few GIs - I got multiple opinions - suggested my inflammation was presenting itself in a way where I could feel it in my rectum.
I was offered the 'opportunity' to have an observation under anesthesia, akin to what a surgeon would do if an abscess/fistula needed to be removed, but both GIs said the MRI gave them more than enough confidence to say this wasn't needed. I opted to avoid this and just get going on my infusions - over the past 3+ months, I've had an abscess drained, fistulotomy, sigmoidoscopy, TWO CT scans, TWO MRIs, an anoscopy and more doctors calls/visits than I can count off the top of my head. I decided it was time to believe my doctors and get treated.
So in conclusion, Stevo68: I am glad to hear nothing was found and relieved in a way, because it seems we were both concerned about
imaging/doctors disregarding physical symptoms when in fact we just weren't sure what was causing them. I'm hopeful we'll both get better fast without requiring any additional rectal surgery
