In her paper, ‘Sharing online clinical notes with patients: implications for nocebo effects and health equity’, Blease bridges findings from two research fields to describe possible unintended consequences of providing patients access to clinical notes.1 She explains how nocebo effects, genuine psychological and physiological reactions following negative expectations, may arise after patients read such notes. Blease emphasises that the likelihood of nocebo may be greater for those patient groups who experience stigmatisation in healthcare. We argue that this is the case for patients with so-called medically unexplained symptoms (MUSs) and that clinicians who work with them should consider nocebo but not for the reasons they may think.MUS is a term used to refer to persistent physical symptoms which cannot be fully or reliably attributed to a structural pathology. They include common symptoms such as chronic or recurrent pain in joints and muscles, fatigue, paresthesia or digestive issues. MUS may persist indefinitely and vary in severity, often accompanied by chronic psychological distress such as anxiety and depression.
