Part of the What Do I Do Now? Pain Medicine series, Psychological and Psychiatric Issues in Patients with Chronic Pain presents a variety of succinct case studies and “curb-side” consults on the complexity of chronic pain and its successful management. Chapters present models for understanding issues related to chronic pain within a psycho-social context, including cases on specific psychological or psychiatric issues, as well as broad considerations such as selecting among behavioral therapies options and the use of complementary therapies and non-opioid analgesics. Recognizing that most clinicians do not always have the time or resources to conduct the type of psychological assessment that each case may require, chapters focus on the key elements of each diagnosis, covering background information, assessment approach, treatment recommendations, and key points to remember.
