Previous studies have shown that pain memories have a profound impact on subsequent pain experiences. This study investigated whether pain ratings derived from other people can modify an individual's memory of past pain. This study also examined whether pain memory modified by others' pain ratings determines subsequent pain experiences. ⋯ The study demonstrates the importance of social information on pain and provides evidence that this type of information substantially modifies the subsequent experience of the same pain. These results suggest that social information on pain can be used to alleviate pain associated with recurring medical procedures and thus increase patients' willingness to continue treatment.

Pain science education (PSE) is commonly integrated into treatments for childhood-onset chronic pain. A core component of PSE is learning about, and often reconceptualizing, the biology of chronic pain. Yet, few interventions have been developed specifically for young adults and little is known about how young adults conceptualize the biology of pain. This study used a qualitative methodology to examine how young adults with childhood-onset chronic pain understand the biology of pain, and the language they use in this meaning-making process, which may inform future interventions tailored to this age group. ⋯ This study provides new qualitative insights reflecting a variety of ways that young adults with childhood-onset chronic pain conceptualize pain. Some conceptualizations of pain align with modern pain science principles (altered function of nervous and endocrine systems) while others conflict (unhealed injury). Health professionals can use these findings to tailor their pain education interventions by leveraging concepts that 'stick' for youth, being aware of, and interrogating, common misconceptions, and offering language and metaphors familiar to youth.

Women with pain present decreased sleep duration and quality of life, but little is known about the consequences of nighttime pain on overall health. Our goal was to compare levels of anxiety, depression and fatigue in women with pain during the night with those without pain. We hypothesized that pain perception is associated with the worsening of fatigue and mood. ⋯ Our study highlights that women experiencing nighttime pain also reported worse mood outcomes and decreased quality of life, regardless of the level and type of pain. Our data, based on association analysis and not investigating causality, suggest it is important to consider nighttime pain in clinical care to improve quality of life and general health.

Review Meta Analysis
The Relationship of Alexithymia to Pain and Other Symptoms in Fibromyalgia: A Systematic Review and Meta-analysis.
People with fibromyalgia (FM) often report having difficulty with emotional identification and expression, and this "alexithymia" may contribute to their pain and other symptoms. Multiple studies have assessed alexithymia in FM, and we systematically reviewed and meta-analyzed this literature to: (a) describe the prevalence of alexithymia in people with FM; (b) compare the level of alexithymia in FM to both healthy controls and controls with other pain conditions; and (c) determine the association of alexithymia to pain intensity, depression, and anxiety in people with FM. ⋯ Due to the high level of alexithymia in people with FM and the positive relationship of alexithymia with pain and psychological distress, interventions to improve emotional awareness, expression, and processing in FM are recommended.

Applying an ice cube to the temple (the conditioning stimulus) inhibits electrically evoked pain in the forearm. The present study aimed to determine whether temple cooling also inhibits pressure- and heat-pain test stimuli in the upper limb and, if so, to investigate the intra-session test-retest reliability of this response. Additional aims were to establish whether pain inhibition evoked by temple cooling was associated with parasympathetic activity; and to explore sex differences in response. ⋯ The conditioning stimulus in the conditioned pain modulation paradigm is often applied to the upper or lower limbs. This may confound pain-inhibitory effects in people with peripheral neuropathy who typically have enhanced or diminished sensation in the extremities. Applying an ice cube at the temple area induces pain-inhibitory effects on the upper limb after the ice is removed. Future research examining pain modulation in people with peripheral neuropathy may consider adopting temple cooling as the conditioning stimulus.
