Yeah but Hanna, you actually do have proof via untrasound that Liver Flushes healed your GB. The wall going back from 42? (if i'm remembering right) to 3mm proves it. Your ultrasound was a resounding (pun intended) success!
I'd concentrate on the positive stuff that your Ultrasound proves - Liver Flushing decreased your distended GB wall by 1400 percent. That's proof positive. The one stone that still there doesn't nullify the rest of the good stuff that your ultrasound shows!
