Background: Back pain (BP) is a common musculoskeletal symptom that affects a large percentage of the population. Back pain can be classified according to the cause into mechanical and inflammatory. Inflammatory back pain (IBP) has some distinguishing characters that help in differentiation of it from mechanical back pain. Back pain in axial spondyloarthritis is usually of inflammatory type. There are a number of sets of criteria that have been devised to define IBP. These include the assessment of spondyloarthritis international society (ASAS) IBP experts' criteria, Berlin criteria, as well as Calin criteria. Objective: Assessment of overlap of pain character in patients with inflammatory back pain versus chronic mechanical back pain. Methods: Pain, Inflammatory Back Pain, and Chronic Mechanical Back Pain were all looked for in PubMed, Google scholar, and Science direct. References from relevant literature were also evaluated by the authors, but only the most recent or complete study from February 2006 to June 2022 was included. Due to the lack of sources for translation, documents in languages other than English have been ruled out. Papers that did not fall under the purview of major scientific investigations, such as unpublished manuscripts, oral presentations, conference abstracts, and dissertations, were omitted. Conclusion: There is a great overlap in character of back pain between patients with chronic mechanical back pain and those with axial spondyloarthritis.
