Pain continues to be an important public health concern, especially given the opioid crisis in industrialized countries. It is important to understand the association between emotions such as fear and anxiety and the experience of pain as both a physiological and affective experience. Fear or anxiety about pain is in fact a well-known predictor of and close associate of pain. Nociception and pain history differ depending on age, yet little empirical evidence exists on how fear of pain varies over the life span. The purpose of this study was to provide a cross-sectional examination of the relations between age and fear of pain across the adult life span. ⋯ Unique trajectories for different components of pain-related fear exist across the adult life span and may be affected by increased exposure to medical and dental experiences over time and by the awareness of a greater likelihood of experiencing pain later in the life span.

Neck pain is a leading cause of years lived with disability and is often managed with opioid medications in primary care settings, though this is contraindicated by national guidelines. The aim of this study was to determine the prevalence of opioid prescription for neck pain at a primary care visit and to analyze the geographic variation and trends in opioid prescriptions between 2011 and 2017. ⋯ Opioid medication use for neck pain in the primary care setting is significant. Although opioid prescriptions are declining, there remains a need for further standardization in prescription practices.

Randomized Controlled Trial
Feasibility of Auricular Field Stimulation in Fibromyalgia: Evaluation by Functional Magnetic Resonance Imaging, Randomized Trial.
To evaluate the feasibility of recruitment, preliminary efficacy, and acceptability of auricular percutaneous electrical nerve field stimulation (PENFS) for the treatment of fibromyalgia in veterans, using neuroimaging as an outcome measure and a biomarker of treatment response. ⋯ There was a trend toward improved pain and function among veterans with fibromyalgia in the ST + PENFS group as compared with the ST control group. Pain and functional outcomes correlated with altered rs-fcMRI network connectivity. Neuroimaging results differed between groups, suggesting an alternative underlying mechanism for PENFS analgesia.

This is a prospective, blinded, case-control study of patients with chronic pain using body diagrams and colored markers to show the distribution and quality of pain and sensory symptoms (aching, burning, tingling, numbness, and sensitivity to touch) experienced in affected body parts. ⋯ This study demonstrates good performance characteristics of CPDs in identifying patients with NeuP through the use of a simple and easy-to-apply classification scheme. We suggest use of CPDs as a bedside screening tool and as a method for phenotypic profiling of patients by the quality and distribution of pain and sensory symptoms.
