I could be wrong but I don't think stones would present as lumpy things in that area, not even calcified stones. I doubt that this has anything to do with the liver flush, but I am only speculating and could be totally wrong. I don't want to alarm you, but I think this anytime you have odd lumps, moles, growths, etc., anywhere on your body, it is a good idea to get these checked out by a doctor who can refer you for diagnostic testing. While I don't generally like doctors and their heavy reliance on prescribing medications for any little thing, I believe that this is one of those times that it is okay to get professionaly checked out. Better Safe than Sorry!
Good Luck.
