Coccydynia is a painful disorder characterised by coccygeal pain which is typically exaggerated by pressure. It remains an unsolved mystery because of the perceived unpredictability of the origin of the pain, some psychological traits that may be associated with the disorder, the presence of diverse treatment options, and varied outcomes. A more detailed classification based on the aetiology and pathoanatomy of coccydynia helps to identify patients who may benefit from conservative and surgical management.This review focuses on the pathoanatomy, aetiology, clinical features, radiology, treatment and outcome of coccydynia.Pain in the region of the coccyx is referred to as coccydynia or coccygodynia. A convoluted literature exists on its aetiology and management. The term coccydynia was first used by Simpson 1 in 1859, but descriptions of pain in the terminal portion of the spine date back to at least the 16th and 17th centuries.
