A determination is quantitatively made of the severity of pain exhibited at a specified area on an animal by determining the magnitude of cooling required at the area of pain in order for the pain to be masked or made to disappear. The amount of cooling required for pain disappearance is considered directly related to the severity of the pain. Hence, by measuring the temperature depression required to mask the pain in a patient, an examiner can determine just how serious is the pain, and additionally provide guidance in the selection of a specific medicine. There is always some finite temperature depression required for true pain to disappear. Should the patient alleges that no pain relief is encountered by the cooling of the painful area, the examiner considers that the patient is faking his pain.
