Most narcotics tend to be constipating (Imodium works on the same mechanism by the way).If you haven't gone after 3 days (not going for a day or two is still in the normal range) it may be worth trying a stool softener or some Milk of Magnesia until you can stop the pain medication. Glycerine suppositories will sometimes get things moving and are also fairly gentle.If the osmotic/stool softeners do not get things going after a day or so then you may want to try a stimulatory laxative like senna, or try an OTC enema to get things moving. Then if you think the problem will continue then go back to the osmotics/stool softeners.K.
