I take Visanne and Tramacet for my back. It kind of helps as it knocks me out and all I want to do is sleep

I'm a week out from laparoscopy. Nausea, sharp pains in my lower abdomen and lower back. Finally stopped hurting above my belly. Around my belly button constant burning. I take norco every four hours it still doubles me over when it starts wearing off. No migraines but a constant headache but I think that may be from the prometrium. Do you take birth control that may cause the migraines. Are you taking magnesium? I take magnesium and N-acetylcysteine
