Shoulder pain can be from anaesthetic..I had many years ago from another surgery. Left shoulder was painful for approx 6 months. The gas pains went away after 3 days and had little pain at incision but had laparoscopic surgery for bypass. Pain at incision in my experience means been pushing myself and need to rest. Take sensocrat at night for constipation or triphala. Sent from my iPhone using the BariatricPal App
