Susan D,
Right after surgery I found that my muscles and nerves were not quite in sync, and I felt unable to access the correct muscles to evacuate properly. There was also a complete lack of satisfaction if that is the right word, the entire experience felt detached and no longer productive. The more I strained the less came out. The muscles I was activating seemed to be closing down my anatomy instead of opening it up.
Eventually after about a year of frustration I settled into a relaxation approach where I would not strain at all. Very minimal bearing down, and trying to allow the gas to be a force along with gravity.... Not sure if this will help your issue. Take your time in the bathroom, it's a different anatomy that you have now and you will need to learn how to use it differently, plus you are still healing and nerves and muscles are not fully operational the way you want them to be. Pouchitis and SBO's or surgical complications just add another layer of problems to the situation and each of us end up sort of having to make it up as we go -when the Docs run out of answers...
All the best.
