I wish I could help or advise you, but I can't. I too, finished radiation treatment in late March. Early in my treatment I had a little urination issue and was given Flomax which took care of the problem. I'm not certain that it was actually any worse than before. I had a loose stool, but that seems to have resolved itsself. At this time I am after effect free. I'm sorry you are having so many problems and wish I could help, but I haven't the knowledge.
