Chest pain and palpitations, non-malignant pain, breathlessness and fatigue often endure despite the receipt of appropriate nursing and medical care. This is distressing for patients, impacts on their quality of life and ability to function and is associated with high healthcare usage and costs. The cognitive behavioural approach offers nurses a model to understand how people's perceptions and beliefs and their emotional, behavioural and physiological reactions are linked. Common 'thinking errors' which can exacerbate symptom severity and impact are highlighted. Understanding of this model may help nurses to help patients cope better with their symptoms by helping them to come up with alternative more helpful beliefs and practices. Many Improving Access to Psychological Therapy services offer support to people with chronic physical symptoms and nurses are encouraged to sign post patients to them.In this article, the authors discuss how health psychology can help nurses to help patients to manage physical symptoms which have become chronic. That is those symptoms which continue despite the patient receiving appropriate nursing and medical care. Effective management of chronic symptoms is important for the NHS since patients with such symptoms incur high healthcare costs often through frequent but avoidable use of primary and emergency care (Celano et al, 2016;Kohlmann, Gierk, Hilbert, Brähler and Löwe, 2016;Kroenke, 2014;McDaid and Park, 2015). Nurses in a variety of fields will encounter patients with chronic physical symptoms. Among the most common are nonmalignant pain, acute chest pain and palpitations, breathlessness and fatigue. These symptoms, the scale of the problem and their impact is summarized briefly below. We then discuss the dominant health psychology model for understanding chronic symptoms -the cognitive behavioural model.
