The majority of participants experienced multifocal back pain, which was further subdivided based on the predominant pain localization. In patients with localized cLBP (median: 5\u2009years, IQR: 1\u201310\u2009years), the pain persisted for a shorter time than in the group with predominant back pain other than the lower back (median: 10\u2009years, IQR: 5\u201315\u2009years). The majority of participants did either use no pain medication at all (cLBP: 32%; iLBP: 37%; no\u2010BP(2): 55%) or on\u2010demand medication (cLBP: 56%; iLBP: 56%; no\u2010BP(2): 39%).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Our data show considerable heterogeneity underlying the widespread diagnosis \u201cchronic back pain.\u201d Quantitative differentiation is difficult due to the low pain intensity on the day of the examination, and adequate treatment recommendations are challenging.
