 Background:It is widely known that "pain" can significantly reduce the quality of life (QOL) of patients as well as healthy people. Nevertheless,hardly any large-scale surveys of "pain" have been conducted in Japan,and patients who have pain and their treatment are insufficiently understood. Neuropathic pain is a type of chronic pain that has recently been found to be resistant to non-steroidal anti-inflammatory drugs (NSAIDs),and it is poorly recognized by both patients and physicians.

 Methods:We screened 20,000 men and women 20 to 69 years of age in our large-scale web-based survey to identify patients with chronic pain, and the 3365 patients who met the definition of chronic pain were then surveyed in regard to chronic pain, neuropathic pain, and their satisfaction with existing treatments.

 Outcome:The prevalence of chronic pain among the subjects of the survey was 26.4%, and 24.1% of them, or approximately one in four of the patients with chronic pain, were suspected of having neuropathic pain (6.4% of the subjects as a whole). Medical treatment was discontinued by 72.4% of the subjects with chronic pain who had sought treatment, mostly because of dissatisfaction with its effects.

 Conclusion:Proper early diagnosis and treatment are needed to prevent chronic pain.
