I Had A Biopsy Of A Messenteric Node 8 Days

I had a biopsy of a messenteric node 8 days ago. Surgeon unable to biopsy by laproscopy so incision has 12 staples. Having pain and vomiting from nausea/anesthesia, oxycodone and Zolfran was ordered for the 2 days of hospitalization. Pathology found to be lymphomas. Will see oncologist in 4 more days. My question is I still have slight nausea, no vomiting, but considerable gas pain. Will taking the Zolfran eliminate the gas pain?
