Somatic symptom disorder is a psychiatric condition that is frequently encountered in the primary care and pain medicine settings. Unfortunately, it is often not accurately diagnosed and may complicate existing nonpsychiatric pain conditions. Patients with this disorder focus on the physical component of the pain and, as a result, the psychiatric or core pathogenesis is not effectively treated. This presentation will provide an overview of best approaches for accurately diagnosing and developing an evidence-based treatment plan. We will discuss the history of changing diagnostic criteria for somatization, review current diagnostic criteria, and discuss the treatment plan for those with a somatic symptom disorder and its relationship to chronic pain.
