Thanks for your words John, by any chance is the chanca piedra extract you mention harmful to the liver? As a side effect of this pain and my tests, I at times thought I had some kind of liver disorder, and have become concerned about toxins, and alcohol. I used to do alot of beer drinking in my 20s, so I have self diagnosed myself with everything from fatty liver to chirrosis. The ultrasound impression noted a "normal echogenicity" of the liver without enlargement or focal masses, but I still want to be kind to my liver. It says my common hepatic duct is 3mm, so I'm guessing the primary bilary duct isn't much bigger. The last thing I want is to get one of these stones stuck! So I'm kind of apprehensive about flushing for now. Guess I have to give up the spareribs shucks.
