exquisitely sensitive to the perception that others are not taking their problems seriously. Don't be the one who leaps to a psychological explanation when genuine pain mechanisms are at work. Small fiber neuropathy is one condition that produces disruptive pain with very few clinical signs. Empathetic demeanor and compassionate concern will elicit gratitude from the patient whose diagnosis remains to be determined (Murinson et al. 2008).
In the pain history, the cardinal features include: Quality, Region, Severity, and Timing. It is also helpful to elicit: what is “Usually associated with” the pain, what steps have made the pain “Very much better,” and what has made the pain “Worse,” Table 9.1. Pain severity can be rapidly assessed with a standard scale (Figure 9.1). It is sometimes necessary to establish the cardinal features of more than one “pain.” For example, patients with headaches often experience multiple headache types; each should be characterized and may require different therapy.

In the acute setting, the pain history may be quite brief. In this context, the biomedical model is relevant: what are the proximate causes of a pain problem, what are the pertinent medical conditions. Clinically, we think in terms of “finding a pain generator,” i.e., locating the primary afferent nerve endings activated by an injury. The quick pain history and the biomedical model are typically insufficient when pain is longer‐lasting.
In the chronic pain setting, the insightful provider finds that biopsychosocial history gathering is often more effective. Time is spent establishing rapport and building a relationship (Cole and Bird 2013). The patient with a persistent pain problem will have more extensive relevant experience: prior testing, interventional, conventional, and alternative therapies, and personal perspectives on the cause of their pain. Understanding the patient's insight into their pain strengthens therapeutic alliance (McCormack et al. 2013) (Figure 9.2). Recognizing what the patient values and genuinely enjoys in life becomes essential when implementing a chronic disease model to change behavior, as is necessary in managing persistent pain‐associated conditions. Knowing that patient wants to return to specific sports, hobbies, or work‐related activities will make discussions of “engagement in physical therapy” or “maintaining a moderate exercise program” more successful, couched in terms of returning to valued activities. This is referred to as motivational interviewing, discussed later (Miller and Rollnick 2002).
Figure 9.2 In the effective patient‐provider relationship, there are many forms of communication, patient experiences, and potential outcomes that impact pain care.
For those with cognitive impairments and dementia, it is important to utilize situationally appropriate observations. Pain behaviors in older adults can include irritability, social isolation, grimacing, groaning, sweating, tachypnea, tachycardia, guarding, and limping. For more detail, see Chapter 51.
For children, it is important to conduct an age‐appropriate pain assessment. Children over the age of 7 should be assessed for capacity to utilize the numerical rating scale. From 4 to 7 the FACES scale is more appropriate. Infants and pre‐verbal children require behavioral pain scales such as the FLACC and the NIPS. Please see Chapter 50 for more details.
Emotional impact
Some patients will become irritable when socioemotional barriers are explored. Others will express sincere appreciation that you want to understand their experiences more fully. By empathetically entering into the patient's experience you can lighten their burden while fostering genuine connection that will be a strong foundation for future progress (Rogers 1967). More in Chapter 10.
Sleep
The quality and quantity of sleep has a direct and profound influence on pain persistence and severity. It is critical to ask about sleep at the initial visit and to check back about sleep quality and quantity at subsequent visits, see Chapter 25 for details.
Function
Pain has a profound effect on multiple domains of function as noted in Chapter 1, Figure . Functional assessment in patients with pain, usually focuses on specific domains, noted here in Table 9.2.

Biopsychosocial model
The degree to which the patient will recognize aspects of the biopsychosocial model is expediently explored with an educational handout about the model. The patient, once introduced to the concepts, see Chapter 8, is presented with a check list, such as that in Table 9.3, providing the opportunity to endorse multiple complicating factors.
