Not to be difficult, but NSAID's may be worse than a lesser amount of a stronger pain killer, especially since you will have to take a very high and frequent dose if your pain is bad. They cause stomach ulcers/problems and some of them are toxic to your liver in high doses. The Bangkok Post did a write up a month or so ago about the dangers of NSAID's.
