The term pain management applies mainly to chronic pain rather than acute pain. In its broadest sense it includes a range of physical (e.g. spinal cord stimulation) and pharmacological (e.g. opioid drugs, intrathecal pumps, facet joint injections) as well as psychological interventions. Although the purpose of physical interventions is to reduce the intensity, frequency and duration with which pain is experienced, the overall aim of pain management is to ameliorate the experience of pain in its broadest sense rather than to eradicate it. Acute pain, such as postoperative pain, is expected to have a self-limiting time course and treatments are primarily directed at preventing its occurrence or reducing the magnitude of experienced pain during this period of time. This approach has been transferred to many medical treatments of chronic pain (such as those listed above) but while the elimination of pain is a worthy goal for chronic pain sufferers it is generally not possible with our present understanding of the neurobiology of chronic pain. By definition chronic pain is longstanding, usually defined as greater than six months but often many years. Most sufferers will have received a wide range of pharmacological treatments without experiencing complete relief. When pain persists over a period of time its impact becomes widespread, it needs to be considered as a multifaceted construct and its treatment is necessarily more complex. This chapter is therefore concerned primarily with psychological approaches to this problem.
