Uncertainty: perennial controversies in pain understanding

As I write this post today, yet again there are new theories being proposed for that most common of experiences: pain. Not only theoretical controversies, but even the definition of pain is being debated – is pain an “aversive” experience? An aversive sensory and emotional experience typically caused by, or resembling that caused by, actual or potential tissue injury. Some researchers have recently “found” a new nociceptive fibre (though they persist in calling it a “pain fibre” – once again perpetuating the idea that pain is one and the same with nociception). One of the conversations is whether pain is a sensation, or an emotion, or something else. When I went to University and studied psychology, sensation was defined as “information transmitted by sensory receptors” – in other words, activity in the sensory receptors prior to perception is classified as sensation. Emotions are also defined in psychology, and depending on the theory being followed might be defined as “a complex reaction pattern, involving experiential, behavioral, and physiological elements.” Perception involves recognising and interpreting sensory information, and invokes the idea of awareness as an essential feature. (This is a good place to begin searching for definition – click) The term aversive indicates “a physiological or emotional response indicating dislike for a stimulus. It is usually accompanied by ...

Brucella is a facultative anaerobic Gram-negative bacillus. It resembles Mycobacterium tuberculosis and establishes infection intracellularly. Brucella infection shows a strong tissue preference for the reproductive system, bone, and fetal ectoderm (de Figueiredo et al., 2015). Early manifestations of brucellosis consist of fever, sweating, joint pain, symptoms of poisoning, chronic spine arthritis, testis or ovarian inflammation, and neurological complications. The prognosis of brucellosis tends to be poor and can result in disability if an early diagnosis was missed and/or no timely treatment was initiated.

Pediatric chronic pain is associated with risk of impact across social, emotional, and behavioral domains at child and family levels.30,52,67 Extant literature highlights psychosocial factors that can foster resilience and others that underlie vulnerability for poor pain coping and disability. Resilience factors, such as pain acceptance and psychosocial adjustment, have been found to promote the use of adaptive pain coping strategies within this population.14 Greater child and parent pain catastrophizing, clinically significant internalizing symptoms (e.g., anxiety, depression), and maladaptive parent responses (e.g., over...

Semin Musculoskelet Radiol 2019; 23: 376-391 DOI: 10.1055/s-0039-1693661Axial spondyloarthritis (axSpA) is a chronic inflammatory condition that encompasses ankylosing spondylitis as well as nonradiographic axSpA and can lead to chronic pain, structural damage, and disability. The disease is strongly associated with the presence of human leukocyte antigen-B27. Early diagnosis of axSpA is significant due to new treatment regimens leading to reduction of inflammation and potentially delaying disease progression. Imaging of the sacroiliac joints and the spine plays an important role in the early diagnosis of spondyloarthritis...

ConclusionsStrongly believing that thinking about pain helps you solve problems or cope with pain (positive metacognition), or that it is harmful and uncontrollable (negative metacognition), can increase the amount you worry or ruminate as pain increases. This is associated with increased pain catastrophizing. Identifying and modifying these unhelpful pain metacognitions may improve treatments for pain catastrophizing and thereby chronic pain generally.

Authors: Michaelides A, Zis P Abstract Pain is a subjective experience that is influenced by genetics, gender, social, cultural and personal parameters. Opposed to chronic pain, which by definition has to last for at least 3 months, acute pain is mostly because of trauma, acute medical conditions or treatment. The link between mood disorders and acute pain has proven to be increasingly significant since the link is bi-directional, and both act as risk factors for each other. Depression and anxiety are associated with increased perception of pain severity, whereas prolonged duration of acute pain leads to increased ...

The burden experienced by adults with chronic pain extends to their children, who are at increased risk for developing chronic pain compared to children of parents without pain.32 Research with clinical, community, and epidemiological samples consistently shows increased risk of chronic pain and disability among offspring of adults who have chronic pain,11,28,53,59 and a large (n>5000) family linkage study demonstrated that maternal and paternal chronic pain increased the odds of chronic pain in adolescents.

Complex regional pain syndrome (CRPS) type I and CRPS type II diminish quality of life and can lead to significant disability.15 Both conditions have varied and complex clinical features, with chronic debilitating pain being the primary symptom, usually involving the lower or upper extremities.16,24 The conditions are differentiated by the absence (CRPS-I) or presence (CRPS-II) of demonstrable nerve damage as an underlying etiology.

Today’s post is another one where there’s very little to guide my thinking… Have you ever wondered why we read so much research looking at the characteristics of the people who look for help with their pain – yet not nearly as much about us, the people who do the helping? There are studies about us – thanks Ben – and others! (Darlow, Dowell, Baxter, Mathieson, Perr &Dean, 2013; Farin, Gramm &Schmidt, 2013; Parsons, Harding, Breen, Foster, Pincus, Vogel &Underwood, 2007). We know some things are helpful for people with pain: things like listening capabilities (Matthias, Ba...

AbstractDirect-to-consumer television advertisements forLyrica in the United States create narratives of gendered domestic normalcy to which women with fibromyalgia are encouraged to aspire through pharmaceutical intervention. This paper unpacks images and narratives within these advertisements to demonstrate that they rely on metaphors that represent gendered expectations in order to evoke guilt and provoke a desire for what Joseph Dumit calls “health as risk reduction,” and what I argue is an attempt to show disability being erased. Following Stuart Hall’s Encoding/Decoding model of communication, viewe...
