The medical treatment will come in bundle/package, not in singles. It means most of post surgical problems , which you mentioned ,will be relieved by simple medications. But remember one point: severe pain
in the abdomen, severe vomiting
and not able to pass even gas, abdominal distension - these symptoms show Intestinal Obstruction
- can be relieved by medication and simple surgical procedure, if neglected, otherwise can lead to threatening problem.At any time if you face all these problems together, my sincere advise is, to consult the doctor immediately.
