Andrew PY - 2018 T2 - Harrison's Neurology in Clinical Medicine, 4e AB - The province of medicine is to preserve and restore health and to relieve suffering. Understanding pain is essential to both of these goals. Because pain is universally understood as a signal of disease, it is the most common symptom that brings a patient to a physician’s attention. The function of the pain sensory system is to protect the body and maintain homeostasis. It does this by detecting, localizing, and identifying potential or actual tissue-damaging processes. Because different diseases produce characteristic patterns of tissue damage, the quality, time course, and location of a patient’s pain lend important diagnostic clues. It is the physician’s responsibility to provide rapid and effective pain relief.
