When a painful injury or pathology is resistant to treatment and persists, when pain persists after the injury or pathology has healed, and when medical science cannot identify the cause of pain, the task of medicine is to relieve suffering.
Kada je bolna ozljeda ili patologija otporna na liječenje i uporna, kada bol ostaje i nakon što je rana ili patologija zacijelila, i kada medicina nemože identificirati uzrok boli, zadatak medicine je da smanji patnju.
