Pain is one of a range of common symptoms experienced by palliative patients. Keep in mind that a patient with a life-limiting illness can experience, on average, 12 or 13 different symptoms through their disease trajectory.
Pain is defined by the International Association for the Study of Pain as ‘an unpleasant sensory and emotional experience associated with actual or potential tissue damage’. Each of us has a number of influences that affect the way we perceive pain. The important thing to appreciate is that the perception of pain is unique to the individual.
The pathophysiology of pain is complex. Although it may help to classify pain as nociceptive or neuropathic to guide management, the reality is that pain is a syndrome with neuropathic, nociceptive, emotional, and psychosocial overlays. The cause of pain is often multifactorial and can involve the disease, its treatment, previous experience, and pre-existing morbidity. Not surprisingly, the management of pain is complex but it always begins and ends with assessment.
