I'm definitely 50-50 on what approach is best for me. I don't feel much pain but I can feel my gallbladder trying to do its work. I think (w/o getting a scan) it's having difficulty because of the stone at or in the neck. My evidence is both from this squeezing feeling and color of BMs.
It's hard to assess whether flushing can get the smaller stones out around the larger stone. Of course when I talk to my doctors they don't or cannot comment on this kind of method.
