Pain in lower back and at takedown site

I cannot comment on the back because I do not know for sure

Scar tissue pain can last years later unfortunately, here is an article

I recently had an abdominal ultrasound and the tech showed me on my abdomen where my pouch starts and I was surprised at how high my pouch starts, Right up and to the left of my belly button. So I think that pouchitis pain can be quite high, near the takedown site.

That's really helpful.  I'd be curious to see where my connections are in relation to where I feel things in my abdomen.  I've had some rough patches, but overall good for a long a time. I'm grateful the antibiotics work.

After my 2nd takedown (first failed because of an undetected leak), I got pouchitis right away.  Each bout was always preceded by terrible pain in my tailbone area.  My GI said I had a small sinus tract but that didn’t go anywhere, but it was located in the back of the pouch.  After a couple of years we did a CT Scan and they found a pocket of air that was connected to the sinus tract.   I went to Cleveland Clinic 3 years ago, where a great doctor did a MRI, saw where this abscess was pushing on the jpouch and was able to remove it.  No more tailbone pain after that. Although I still have chronic pouchitis it is manageable now for me with Cipro and Flagyl.  It might be worth getting a CT Scan done.
