Could Intestinal Problems Be Normal Post Correction Surgery For Broken Leg?

I'm about 7 weeks out from surgery correction of broken leg. I'm currently not taking Norco any longer but that could change when PT starts. Since I don't get along with narcotics I was only taking half pills & had gotten them 8 hours apart. 5 days ago I quit taking them & I'm using Advil as needed. Anyway, I'm having a lot intestinal issues and would like to know if that's common. If so what can I do and if not, any suggestions what I need to consider doing?
