Chronic pain and comorbid posttraumatic stress disorder: Potential mechanisms, conceptualizations, and interventions

Posttraumatic stress disorder (PTSD) is a common comorbidity to chronic pain, among others due to potentially shared posttraumatic origin. There has been growing interest in this field in the past decades, also providing some important studies to support our understanding of this comorbidity and how to address it in clinical practice. However, there are still important questions, particularly regarding the potentially shared vulnerabilities, mutually maintaining mechanisms, and how to best treat this comorbidity. This article provides a brief and up-to-date review of what we argue to be some of the most important studies within the field of chronic pain and comorbid PTSD and will discuss some of the current challenges and ways forward.
