Coccydynia is pain in the area of the coccyx (tailbone). It is a small, curved, V-shaped bone at the bottom of the spine.

The tailbone can be found at the end of the spinal column. It supports the body in a sitting position and helps transfer body weight during changes in sitting positions. It is also an area where muscles, nerves, ligaments, and tendons from other locations in the body come together. Excess pressure can affect these structures.
In most cases, the specific cause of coccydynia is unknown. Other times, it may be caused by:
- Trauma or injury from falls
- Tailbone shift during childbirth
- Other stress that affects that tailbone
Pain can come from bones, muscles, nerves, or supporting structures.
