I also had surgery on the 27th! Didn't have problems with gas but I still have pain on the bigger incision which for me is right in the middle of my abdomen. I have like a burning sensation and I get these sharp pains all the time. I guess it's the healing process. I still haven't had a bowel movement, I bought the milk of magnesium but don't know when to take it or how much of it. Any suggestions?
