Yes, Scott - we can rule out gyn! Its interesting you mention kidney. When I was much younger, I was prone to kidney infections and I believe I do have one kidney that is somewhat atrophied as a result. However, my more current health issues (UC, pouch, etc) and location of pain I think would kind of make a kidney issue unlikely.
I've never really had any type of adhesion issue, and my pain is not constantly to the right near my stoma scar, so I don't think that'd be the issue, either. The fact that I go days feeling OK and then days feeling real bad is very puzzling. Today (so far) is a good day.
I've noticed that, especially when feeling lousy, my transit time for BM is much longer. I didn't end up using the rest room until this morning after eating dinner last night....that is somewhat abnormal for me.
For now, still taking ABs for possible SIBO, ordering supplements as mentioned above and mulling over a new GI.
Thanks all
