Abstract
<p id="d8137268e119">Chronic pain is a common, complex, and distressing problem that
has a profound impact
on individuals and society. It frequently presents as a result of a disease or an
injury; however, it is not merely an accompanying symptom, but rather a separate condition
in its own right, with its own medical definition and taxonomy. Studying the distribution
and determinants of chronic pain allows us to understand and manage the problem at
the individual and population levels. Targeted and appropriate prevention and management
strategies need to take into account the biological, psychological, socio-demographic,
and lifestyle determinants and outcomes of pain. We present a narrative review of
the current understanding of these factors.
