Hey! I felt the same way had a similar situation when I had my surgery in April 2nd. I felt gassy but wasn’t expelling gas from either end. When I finally passed gas and began burping, I felt so much better. Sipping drinks helps cut back on the “puking” feeling. I had complications but now I’m feeling better. Walking/standing also helps move the gas around and it made me start feeling a lot better. Hope this helps!
