Excerpt from Abdominal Pain Its Causes and Clinical Significance None can be more conscious of the imperfect results of his efforts than he who seeks to solve the mysteries of pain. An abstract quantity, it allows of neither visual observation, tactile perception, nor physical measurement. It, therefore, admits of none of those tests which it is possible to apply to nearly every other symptom of disease. Our estimate of it can only be formed by what we feel ourselves, and what we vaguely assume must be felt by others. If I ventured to suggest the way in which I would hope this small work might prove of service to the busy practitioner in the differential diagnosis of obscure abdominal disease, it would be that, when confronted with pains the significance of which he cannot clearly construe, he should first turn to the chapters on the regional manifestation of pain, and seek among the causes there given the possible organ affected. With this as a workable basis he should next turn to those chapters which contain a fuller description of the symptoms exhibited by the disease of the particular organ under suspicion. But the search should not end here. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
