Your upper back, right shoulder and neck pain sound like mine. That is the main reason why I am flushing. I have done 23 and while the pain is much better, it is still there. I cannot find the link, (I keep some of his responses in a Word document) but here is Andreas's explanation on why ALL stones must be cleaned out before any persistent symptom goes away.
"The body can form stones throughout the liver, but when they are released they will have to go through the main two ducts that combine to form the common bile duct. While liver cleansing, stones from the more distant areas of the liver will end up in either of these main bile ducts. Even towards the end, a small number of small stones can cluster together and form one larger stone, enough to obstruct the bile flow and cause the same digestive problems that may have occurred when Liver Cleanses were started. That's why, to clear persistent symptoms, all stones have to come out."
By the way, I have been to chiropractors all of my life and they have always been very helpful to me except with this problem. My neck and shoulder (right side) just remain too tight to adjust, although this is much better and there is more cracking sounds every time I go.
Unfortunately, with this type of pain, it just takes a while so hang in there. You can do it!
