I'm one week post op today. This just started happening to me yesterday. I never had any gas after surgery, so this baffles me. Last night I took gas-x and slept with a heating pad. Woke up this morning fine, but by 1:00 I felt it happening again. I did go back to work on Day 4 post op, so maybe I'm overdoing it. Other than that, I feel great!
