Coccygodynia is a rare condition in that causes pain in and around the coccyx (tailbone). Although various causes have been described for the condition, the more common causes are direct falls and injury.

A number of different causes have been associated with coccygodynia. However, the most common cause is a direct fall and injury to the area of the sacrum and coccyx. These types of injuries can occur from various activities, examples include a kick, an injury on a trampoline when one hits the bar or springs that surround the trampoline jumping pad, or from falling from a horse or skis. Another common cause, exclusive to women, is childbirth. The other most common cause of the condition is pregnancy. During the last three months of pregnancy, certain hormones are released in the women's body causing the area between the sacrum and the coccyx to soften and become more mobile. The increased mobility may result in permanent stretching and change and causing inflammation of the tissues surrounding the coccyx. In about one third of all cases of coccygodynia, the cause is unknown. Other less common causes include nerve damage, cysts such as Tarlov cysts, obesity, and a bursitis like condition that can arise in slim patients who have little buttocks fat padding.

Treatment for coccygodynia generally falls into conservative management or surgical intervention categories. The conservative approach typically includes hot sitz baths, NSAIDs, stool softeners, and/or the use of a donut-shaped pillow or gel cushion to descrease pressure and irritation of the coccyx. If these treatment options fails, glucocorticoid injections may be used in an attempt to reduce the pain. Massage therapy has also been used to help decrease pain, but most studies have shown that the relief experienced from this form of therapy is temporary. The more aggressive and rare approach involves either partial or complete removal of the coccyx (coccygectomy).
