who said that they had chronic diarrhea due to the PN. They even called it explosive at one stage,and told me that it was very difficult to deal with.

I don't know to what extent this information may help you, but if it is PN related, it may go away just as quick as it surfaced. If it is because of other medical reasons, than that needs to be examined. I would definately talk to your doctor about it though,as I am sure they can help with suggestions.

Sorry I could not be more help-
