I am only 4 days post op, but I have been having horrible pain under my left rib. It will ease up with massage and laying on a heating pad, but it eventually comes back. I know what you mean about making yourself burp, I have to do that too. I have a hard time breathing and bending over. I know it can be gas but man this stuff hurts!! 2 days post op I thought I was having a heart attack . This stuff is gong to have to give in a few days or my Dr,. is going to have to do something. I have not even had my first fill yet either. Have you found anything that helps and does it go away? I can't live like this!! I am sucking on a ginger candy right now that I got at the herbal store, I have GasX'd myself to death already.....please share any advice TY
