Pain is a major ailment that motivates individuals to look for treatment. Despite its enormous clinical relevance, very little is known about the factors that influence our preference of an analgesic (or pain-relieving treatment). The current study investigated the influence of the information regarding the probability and the magnitude of the expected analgesic effect on preference of analgesic options. ⋯ Our findings revealed that preference of analgesic options is mediated by the overall probability of analgesic effect and the relative potency of analgesics. The expected relief one imagines to obtain from analgesics would guide preference. The findings highlight the importance for clinicians to understand how patients subjectively frame the probability and magnitude factors related to decision making in medical context.

Unusual symptoms such as digit misidentification and neglect-like phenomena have been reported in complex regional pain syndrome (CRPS), which we hypothesized could be explained by parietal lobe dysfunction. ⋯ In patients with chronic CRPS, detailed clinical examination may reveal parietal dysfunction, with severity relating to the extent of allodynia.

The painDETECT questionnaire (PD-Q) has been used as a tool to characterize sensory abnormalities in patients with persistent pain. This study investigated whether the self-reported sensory descriptors of patients with painful cervical radiculopathy (CxRAD) and patients with fibromyalgia (FM), as characterized by responses to verbal sensory descriptors from PD-Q (sensitivity to light touch, cold, heat, slight pressure, feeling of numbness in the main area of pain), were associated with the corresponding sensory parameters as demonstrated by quantitative sensory testing (QST). ⋯ Clinicians and researchers should be cautious about relying on PD-Q as a stand-alone screening tool to determine sensory abnormalities in patients with FM.

Radon therapy is clinically useful for the treatment of pain-related diseases. However, there have been no studies regarding the effects of radon inhalation on neuropathic pain. In this study, we aimed to determine whether radon inhalation actually induced a remission of neuropathic pain and improved the quality of life. ⋯ This study showed that inhalation of 2000 Bq/m(3) radon prevented and alleviated CCI-induced neuropathic pain in mice.
