Hello! Thank you for the query. It would be much easier to answer your question knowing at least pain location. Also the type of laparoscopic surgery (gallbladder removal?) is important. Back pain and abdominal pain can be caused by gallstones, stone in the bile ducts, pancreas inflammation or urinary tract infection. I assume that you have gallbladder removed. If the pain is connected with nausea, dark urine, whitish stool, a stone in the bile ducts can be the reason. If you have any frequent urinating, burning while urinating, urinary tract infection can be the reason. I suggest you to have some tests done. Abdominal ultrasound, blood work, urine analysis should be done at first. Hope this will help. Regards.
