Hey , I hope you're feeling better since you posted this thread!! I too was having the same issues after surgery with the overwhelming feeling of gas that caused major discomfort. I found out that during surgery they blow your stomach up with Carbon Dioxide so big to where you look like your 9 months pregnant. the main cause of your pains in my opinion is the gas. The only way to get rid of it is to be active and walk. 2 hrs after i had surgery i was walking the halls of the hospital. The nurses and staff said they had never had a patient walk so much as i did after surgery. My dr. informed me that walking is the fastest way to rid your body of the Carbon Dioxide.
