Tailbone pain is defined as pain in or around the coccyx with the triggering or worsening of pain while sitting or sitting to standing position. Tailbone disorders that could be manifested in coccygodynia are injuries (fracture, subluxation, luxation), abnormal mobility of the coccyx (hypermobility, anterior and posterior subluxation or luxation), disc degeneration at sacrococcygeal and intercoccygeal segments, coccygeal spicule (bony excrescence), rheumatic disorders such as ankylosing spondylitis and tumors. Other causes of tailbone pain can be a result of a chronic static and dynamic overload of the tailbone such as obesity, prolonged sitting, bicycling, rowing, riding, pregnancy and childbirth, local infections, anal intercourse, or meningeal cyst. Tailbone pain may begin after certain medical procedures, such as colonoscopy. In patients with a normal mobile coccyx, the cause of the coccydynia is unknown.
