Pitfalls in medicine: pain out of proportion to examination findings

Abstract

Most life-threatening conditions form a coherent clinical picture, with examination findings confirming the patient's history. However, pain out of proportion to examination findings can also signify an emergency – acute compartment syndrome, bowel ischaemia, necrotising fasciitis and acute aortic dissection may all present in this way. A lack of situational awareness leads doctors to erroneously rely on examination findings to flag impending catastrophe, but in such cases misdiagnosis or delayed treatment can have dire consequences. Patients with unexplained pain risk significant morbidity and mortality, and doctors are vulnerable to litigation and reputational damage. This article addresses this danger, exploring the causes and pathology of pain that is out of proportion, and presenting an approach to mitigate risk and prevent catastrophe.
