First thank you to all those who took the time and care to reply. Your replies have helped a lot.
I went to the doc, and she is fascinated, and very open. Only problem is she wants to use me as a guinea pig in terms of blood testing before and afterwards. Mind you, one needle prick isn't as bad as montezuma's revenge on the day.
the pain behind the right shoulder was still there, and she said they call that "biliary colic" so all those who said there are more stones in there are probably right.
In the past I have read here that a repeat flush shouldn't be done for two weeks.
Is that still the current thinking on when to repeat a flush?
