The painful attacks came several times a day; I do exercise, and have one epson salt drank a day. Sometimes enema relievs the pain. In my case: I know how much anger and resentment I stuffed into my liver and gallblader, it was too much cleansings, in a very short time. I wouldn't do a sugery unless it was a life threatening situation. Your ultrasound was normal, and yet the doctor in the ER suggested operation. My awesome flush was #14 where about three dozens huge stones released. I did 2 enemas, which expelled most of them, and the rest colonic flushed out. For a toxic body, it is unlikely 4 or 5 flushes would be enough.
