Evaluating and treating patients with chronic nonmalignant pain, especially with opioid medications, often causes discomfort on the part of primary care physicians. A number of patient-, physician-, and system-related issues converge to make treating chronic pain a complex matter. Patient-related issues include an inability to define a clear anatomic cause for patients' pain, comorbid psychiatric conditions, and past and current substance abuse. ⋯ A paucity of practical clinical practice guidelines, controversy over the effectiveness of opioids on chronic nonmalignant pain, and concern about potential legal and regulatory ramifications add to the complexity of caring for these patients. Possible multifaceted solutions exist to minimize provider discomfort and improve their ability to treat patients appropriately. Examples include comprehensive, practical multidimensional guidelines on the evaluation and treatment of chronic nonmalignant pain, Web-based teleconferenced consultations with subspecialists, reduced pharmaceutical pressure, enhanced continuing medical education and pregraduate training, multispecialty coordinated care of patients with adequate reimbursement for such care, and physician access to state-based systems to track opioid prescriptions.

The psychological behaviorism theory of pain unifies biological, behavioral, and cognitive-behavioral theories of pain and facilitates development of a common vocabulary for pain research across disciplines. Pain investigation proceeds in seven interacting realms: basic biology, conditioned learning, language cognition, personality differences, pain behavior, the social environment, and emotions. Because pain is an emotional response, examining the bidirectional impact of emotion is pivotal to understanding pain. ⋯ The psychological behaviorism theory of the placebo considers the placebo a stimulus conditioned to elicit a positive emotional response. This response is most powerful if it is elicited by conditioned language. Research based on this theory of the placebo that pain is ameliorated by a placebo suggestion and augmented by a nocebo suggestion and that pain sensitivity and pain anxiety increase susceptibility to a placebo.
