Pain across upper back???

Hi everybody, I'm 16 days post-op and feel good except for this pain across my back.I've been passing gas(tmi) so I don't think its that.Has anyone else had this problem.I've been doing fine with my food and liquids and protien! Been walking everyday and pretty much back to my home routine cooking,lite cleaning(not to much)laundry.Can't go back to wor****il I go back to the doc on 5/18 because my jobs(waitress/housekeeper) involve heavy lifting so I have to wait. I hope everyone whos had there surgery this month is doing well and everyone whos having surgery GOOD LUCK LOTS OF LOVE DONNA
