Do Norcos make you sick to your stomach?

I had middle ear surgery (New ear drum from skull graft, cysts removal, and replacement of a hearing bone) a week ago and I have been given Norco 5mg to take every 4 hours as needed. Has anyone experienced nausea or loss of appetite on Norco? Or could it be from my surgery? I have tried contacting my Dr nurse for 2 days with this question with no luck.
