I had surgery Tuesday morning and for the most part feel pretty good. However, any time I take a sip of anything (water, Gatorade zero, protein shake) a few minutes later I feel a rolling pain from my lower abdomen up towards my chest. Is this still gas? Is this the sleeve? I am taking omperozole prescribed for reflux but no other pain meds. Just trying to decide if I keep pushing the fluid or wait till this pain goes away.
