I would just like to add a bit to my previous message.Inflamation can be caused by infection as well as irritation. THe two often go together. If your galbladder is infected it might take a while for the pain and inflamation to go down, even if you do not have any stones inside, but flushing will still help, even if you do not pass any stones.
I have done two flushes since my first, and both had no results. However I passed a large amount on the first one. I may have not given it long enough for more stones to come forward. I think flushing still stimulates the liver regardless of whether you pass anything or not.
