Thats fantastic mate.I suffer from the exact same symptoms. there is quite a few other symptoms associated with it aswell with me. Ive thought that for the last little while it could either be intesusseption or mucosal prolapse the fact you have a diagnosis is extremely positive for this. I will be going for a sigmoidscopy next week and i will be taking all of this information and your testimony with me.
All the best for your surgery next month hope all goes well.
