Dear all,
Unfortunately, I've had a difficult time with my jpouch thus far. My reversal resulted in an anastomic leak that has since healed into a entercutaneous fistula. 
As a result I was on TPN until recently. While I was not eating I would get some liquid bowel movements but they weren't uncomfortable. Now that I'm eating I'm having high frequency, urgency, and severe anal discomfort.
My output is quite well formed so, I know I need to drink more water to make BM's easier. I know all these complaints are quite normal, but my question is in regards to the anal pain/discomfort.
When I have a BM I have an involuntary urge to strain quite hard. After a BM my anus hurts and has difficulty closing again (ie Patulous Anus). It stays open only for a little bit but after closing it can still be very uncomfortable. Baths have helped. The feeling is just like when I was healthy and had severe diarrhea, after many BMs the anus could feel quite unsettled/open. But Again I think this is normal, but I've never seen it described as a patulous anus with a similar feeling as when normal people have diarrhea, I just went to confirm if others have similar experiences?
P.s. I'm not talking about butt burn.
