I had the same surgery years ago. It may take another day or 2 for things to settle down. In the mean time, make sure she has as much fluid as she can manage, even just sipping a little at a time will help. Also, if things haven't improved in the next couple of days, definitely, call her surgeon. Is she still on medication, like antibiotics, or pain meds? Those could upset things, also. hope this helps a little!
