The Language Games of Pain in Nursing: A Wittgensteinian Analysis of NANDA-I Diagnoses

Despite technical and regulatory advances in pain assessment, persistent challenges in recognizing, interpreting, and documenting the experience of pain continue to reveal a structural gap in nursing practice. Traditionally, these difficulties have been addressed from biomedical approaches focused on nociception and objective measurement, without questioning the linguistic and normative conditions that shape what counts as pain in clinical contexts. This article argues that the problem is not primarily technical or instrumental, but conceptual and linguistic. Drawing on the philosophy of language, it proposes to understand pain assessment and diagnosis as language games governed by rules of use that shape the conditions under which certain expressions become intelligible, legitimate, and clinically valid. Based on a conceptual analysis of the pain diagnosis in the NANDA-I taxonomy, the article examines how the interpretive stratification of pain among nociception, subjective experience, and diagnostic categories produces grammatical mismatches that affect clinical communication and foster forms of epistemic injustice, particularly when the patient's testimony does not fit available normative criteria. Through an analytical comparison of different nursing diagnoses and the development of a conceptual case, it is shown that the diagnosis of pain operates more as a normative linguistic device than as a neutral description of experience. The analysis supports the argument that difficulties in pain assessment do not stem from the lack of more precise instruments, but from the rigidity of the rules governing the diagnostic language game. In this sense, the article does not propose a new theory of pain or a clinical prescription, but a philosophical reconfiguration that makes visible the normative character of nursing language and opens the possibility of interpretive practices more sensitive to the patient's lived experience. Understanding pain as a grammatically mediated phenomenon makes it possible to recognize the distinctive contribution of nursing in the clinical encounter and to rethink diagnosis as a relational, interpretive, and ethically situated practice.
