History

Because of the complex etiology and the frequent presence of associated disorders, a general and open-minded approach to the assessment of the patient is needed. Obtaining the history of patients whose symptoms suggest chronic pain syndrome (CPS) is important. A thorough history is necessary for the physician to direct further evaluation and appropriate consultations and to avoid repeating invasive and expensive procedures.

A detailed review of the musculoskeletal, reproductive, GI, urologic, and neuropsychological systems must be obtained. As needed, specific questions should be asked of particular patients, depending on their associated disorders.

Focus the history on a characterization of the patient's pain. Obtaining the characteristics of the pain helps to establish appropriate diagnostic and therapeutic plans.

  • Pain location - The location of pain is an important part of the history; ask the patient to describe the type of pain and the location on a pain diagram (anterior/posterior and lateral view of human picture)
  • Precipitating factors - Ask questions about factors that provoke or intensify pain; this information may provide clues concerning possible etiologies or associated disorders
  • Alleviating factors - Ask the patient if any factors help to alleviate the pain; for example, rest may decrease pain of musculoskeletal origin
  • Quality of pain - Ask the patient to describe the quality of pain; various terms can be used to describe the quality of pain, including throbbing, pounding, shooting, pricking, boring, stabbing, lancinating, sharp, cutting, lacerating, pressing, cramping, crushing, pulling, pinching, stinging, burning, splitting, penetrating, piercing, squeezing, and dull aching
  • Radiation of pain - Ask the patient if the pain spreads or radiates; spreading or radiating pain is a characteristic of neuropathic pain
  • Severity or intensity of pain - Use some type of rating system to evaluate pain severity or intensity with a degree of objectivity and reproducibility; different types of pain scales may be used, with numerical scales being more useful and reliable (the visual analog scale [VAS] is one of the commonly used numerical scales)

The Pain Sensitivity Questionnaire can be used to measure general pain perception (pain perception outside the clinical pain site) in patients with chronic pain. [17]

A 2012 meta-analysis indicates that athletes exhibit higher pain tolerance than normally active subjects, suggesting that regular physical activity is associated with alterations in the perception of pain. [18]

Obtain history specific to the following systems and related disorders:

  • Musculoskeletal
  • Neurologic
  • Gynecologic and obstetric
  • Urologic
  • GI

In addition, a good psychosocial or psychosexual history is needed when organic diseases are excluded or coexisting psychiatric disorders are suggested. Obtain sufficient history to evaluate depression; anxiety disorder; somatization; physical or sexual abuse; drug abuse/dependence; and family, marital, or sexual problems. Somatization is a commonly associated psychologic disorder in women with chronic pain. Somatization scales can be used for evaluation. [19]

Sternbach's 6 D 's of CPS are as follows:

  • Dramatization of complaints
  • Drug misuse
  • Dysfunction/disuse
  • Dependency
  • Depression
  • Disability

Good rapport, tolerance, and an open-minded approach are important when evaluating any patient with chronic pain. A thorough systematic examination usually leads to an appropriate diagnosis and therapy. Patients often have Waddell signs. The disability is usually out of proportion to the impairment and the objective findings.

A patient with chronic pain syndrome (CPS) may exhibit exaggerated pain behavior. Sensations may seem to be hysterical or appear nonanatomic or nonphysiologic, but the patient always should be taken seriously and appropriate conservative steps should be taken.

Detailed examination of the musculoskeletal system is important. Examination of various other systems (eg, GI, urologic, neurologic) also should be performed.
