These ‘second management decisions. Socially isolated people with minor accidents’ are often completely preventable. dominant hand injuries frequently need extra community sup- ports or brief hospital admission. Past medical history, medication and allergy history are important to assist decisions especially regarding appropriate analgesia. Analgesic requirement should always be explored individually. Pain per- ception, self administered analgesics before consultation and prior experience with pain and analgesics often influence decisions of type, strength and method of administration.
