If you are doing only a few and not taxing your system. If you are doing a set of 50 the effect will be different. If you can crank out a righteous set of 25+ @ 225-250 or so most everyone around will be fairly well impressed; I know I would be.
The "real" question though is as asked by another; what are your goals? Answer that and you know where to go. Personally I'd by happy to limit my weight to a respectable amount and increase the reps if it meant being pain free. Finally, have your back checked before it becomes worse.
