Pain that radiates from the neck down the arm, or from the back down the leg, is a common presentation in clinical practice. However, despite the importance of standardisation in physiotherapy practice, there exists an abundance of terms to describe such symptoms, that may not only be confusing to patients, but may worry them unduly if explanations imply that their body is vulnerable or damaged. Therefore, communicating a diagnosis to the patient in a way that is honest, reassuring and empowering is very important. This article also aims to clarify these terms, explain the pathophysiology behind them, consider their limitations in light of recent developments in pain science.
