Coccydynia refers to pain originating from the coccyx, or tailbone pain. Falling, hitting the tailbone, or events such as childbirth can lead to coccydynia.

In most cases, the pain is thought to be caused by an unstable coccyx, which results in chronic inflammation of the sacro-coccygeal joint. Women are much more likely to experience coccydynia, since they have a wider pelvis, making the coccyx more exposed.

Coccydynia can be treated non-surgically with anti-inflammatory medication, injections, or a "donut" pillow to sit on. In severe cases the coccyx can be removed (coccygectomy).
