Generally where one has been injured by another's wrongful conduct he is required to exercise ordinary care and reasonable prudence to seek medical treatment so as to minimize the defendant's damages. Failure to do so may diminish the amount of damages the injured person may recover. This is a fundamental principle of the law of damages, and not of tort.
