Pain after cleansing. Help!!

I have done about 6 or 7 Liver Flushes in the past 2 years. I started doing them after an episode of what I believe was a stone passing through. It was the worst pain ever and totally disappeared in seconds after it felt like glass slicing my insides. I started doing the Liver Cleanses and have gotten out hundreds of stones. I always seem to be fine for a couple of months afterwords until I get a little twinge and then I do another one. Well, I did one about 2 months ago, got out a few stones and have been in pain since. I dont eat except a few things because of the pain. I have lost 15 pounds in 2 months. I finally went to the doctor and they did an ultrasound. It showed absolutely nothing. No stones, no inflammation, no fluid, nothing. I am planning on doing another cleanse because I think I might have a stone stuck that they didnt see. She suggested I get tested for H. Pylori because it could be an ulcer. But its under my right rib cage, sometimes around to my back and hurts the most when I eat fat. Sounds like gallbladder. I have had a test for H. Pylori and it came back positive about 2 years ago. I did the humaworm cleanse and figured I had gotten rid of it but was never tested again. Has anyone had any of this?
