Hi, I also had a pain in my right side for along time and the first thing my dr. said without any testing was kidney stones. He was right on. Did your Dr. do any x-rays beside the scope down your throat? I don't know anything about Bile. Try useing the Mayo Clinic in Rochester MN. website. They have excellent information on all medical issues.
Good Luck. It also doesn't hurt to get a second opinion, I have learned to reseach and ask questions.
