Chronic pain is a common, costly, and consequential health problem. However, despite some important analytic contributions, sociological research on pain has not yet coalesced into a unified subfield. We present three interrelated bodies of evidence, and illustrative new empirical findings using 2010-2018 NHIS data, to argue that pain should have a central role in sociological investigations of health. Specifically, we contend that (1) pain is a sensitive barometer of population health and wellbeing; (2) pain is emblematic of many contested and/or chronic conditions; and (3) pain and pain treatment reflect, and have wide-ranging implications for, public policy. Overall, whether we analyze pain quantitatively or qualitatively—focusing on its distribution in the population, its social causes and consequences, or its subjective meanings for individuals—pain reflects the social conditions, sociopolitical context, and health-related beliefs of a society. Pain is thus an important frontier for future sociological research.
