Depending on the cause of the disease, the pain is caused by the dislocation of the caudal fracture, which is displaced forward or laterally by the pulling of the caudal muscle and the anal raphe. The pain is lighter when standing still or lying down, and it increases when sitting or straining in stool; and there is localized pressure pain. There may be caudal pressure and abnormal activity on anal palpation, and sometimes the fractured end and displacement may be palpable. Most of the symptoms are milder in cases due to other causes, especially in congenital and long-standing cases. Based on the clinical presentation, X-ray examination can assist in the diagnosis. Caudalgia can be diagnosed by anal palpation with caudal bone pressure and abnormal activity, and sometimes fracture ends and displacement can be palpated. The etiology of caudal bone pressure and abnormal activity is unknown and may be related to trauma and deformity. A variety of factors can cause this disease, including central lumbar disc herniation, sacral tumors or cysts, arch rupture with slippage, and many others.
