My mom had this last spring and had to have emergency surgery to remove her gall bladder. She was in a lot of pain. It came and went over a period of three weeks before we figured out what was going on. She would call me and want to go to the hospital but when the paramedics got to her house and I drove across town to see her she would be feeling better again. This went on three times before she finally decided to go to the hospital. There they found out here bile duct and gall bladder had some gall stones and she had the operation. So I know what type of pain you are talking about. She too had to have a stent installed and after a few weeks they removed it and rechecked her bile duct. She's doing better now. Hang in there and do your best. That and hope that the doctors can help you though the pain.
