In Capelouto v. Kaiser Foundation Hospitals (1972) 7 Cal.3d 889, the trial court had failed to instruct the jury on the infant plaintiff's pain and suffering; our high court reversed the jury verdict that awarded only plaintiff's medical expenses. It was observed, with respect to pain and suffering, that "admittedly these terms refer to subjective states, representing a detriment which can be translated into monetary loss only with great difficulty. But the detriment, nevertheless, is a genuine one that requires compensation , and the issue generally must be resolved by the 'impartial conscience and judgment of jurors who may be expected to act reasonably, intelligently and in harmony with the evidence.'" ( Id. at p. 893.)
