Abstract

Pain is a multifactorial, unpleasant sensory or emotional process associated with or described in terms of tissue damage (International Association for the Study of Pain (IASP), 1986). This definition emphasises the relationship between the objective (physiological) aspects of pain and its subjective (emotional and psychological) components. The response to pain can vary significantly not only between individuals, but also within the same person, depending on the conditions under which the pain occurs.
