I still have my gb. Though it was inflammed, walls 42mm instead of 3 mm, stone in the neck. I solved it with flushing. At the last US the stone was still there but now free floating and the other problems went back to normal.
There are several people that had gallbladder surgery and ended up doing the liverflushes and that helped them. Pain from the liver can travel to other spots.
Since the forums are moving so fast some of the good messages get lost. I would suggest to look for Flowerchild59 on the liverflush forum, she was the most active one in my time about answering the questions about people without gallbladders and problems. If you just can find 1 message you can click on her "all messages". It might be that it is about 3 months or more when I saw her name.
