I've had 4 lap surgeries and 1 appendix removal via key hole surgery and the shoulder tip pain after the appendix was by far the worst of them. The only difference with that surgery was that I wasn't up and about until the next day due to low blood pressure and severe nausea so there was a lot of gas to get rid of when I was finally able to get up and about! I found "Degas" tablets from the chemist worked well for me 😊
