Dear friend,
The combination of medicines given to you by your doctor- acetaminophen and codeine (oxytocin, endocet, Percocet) is used to relieve moderate to severe pain. But as of now, no herbal drug is strong enough to kill severe pains. If any drug is available (like tradamol), they are narcotic also. Your pain will decline soon with good immobilization and by the normal healing of fracture. Good luck.
