We discuss two broad issues that arise from Sharpe and Greco’s article, one relating to the assumptions they make about MECFS and its treatment specifically, and the other relating to their conceptualisation of the illness/disease dichotomy. We argue that the term “illness without disease”, in the sense that Sharpe and Greco use it, is problematic because it can lead to unwarranted causal assumptions. Following these critical comments, we present a new framework for conceptualising the relationship between explanatory disease models and the experience of illness.
