Chronic opioid therapy (COT) for chronic noncancer pain (CNCP) is characterized by both high rates of patient-initiated discontinuation and by perceived helpfulness among those who sustain opioid use. This study examines predictors of the desire to cut down or stop opioid therapy among patients receiving COT who report that opioids are helpful for relieving pain. ⋯ There are high rates of ambivalence about opioid use among COT recipients who consider opioids helpful for pain relief. Depressed patients are more likely to be ambivalent about use of prescribed opioids. Eliciting patient ambivalence may be helpful in patients who are not benefiting from long-term opioid use as an initial step toward consideration of discontinuation.

To describe the prevalence and characteristics of flare-ups of chronic nonspecific back pain (CNSBP) among primary care patients, and to examine associations with measures of pain severity and psychosocial factors. ⋯ Flare-ups of CNSBP are common among primary care patients, and are independently associated with higher levels of pain intensity, disability, and passive coping. The presence of flare-ups and the perception of activity as a trigger may predispose patients with flare-ups to experience disability not explained by pain intensity alone. Further longitudinal studies are required to better characterize CNSBP flare-ups and determine their clinical implications.

With the exception of interdigital neuromas, cutaneous neuromas are relatively rare and often present a diagnostic challenge. ⋯ The diagnosis of cutaneous neuroma should be considered in all patients who have intractable pain and allodynia at unusual locations and in atypical patterns. In addition, ultrasonography can prove very useful in the detection of small cutaneous neuromas if the site of symptoms can be precisely localized.

To examine the relationship between knee pain, altered somatosensation, and self-reported instability in individuals with knee osteoarthrosis (OA) during a step-up-and-over task. ⋯ Severe OA may result in both hyperalgesia and hypoesthesia at the affected knee. Perceived instability during functional tasks may be mediated in part by pain in individuals with knee OA.
