The coccyx is the anatomical name for the tailbone. The sacrum is the lowest part of the spine and consists of a number of vertebral bodies that are fused together.
The tailbone, or coccyx, is the name given to the remaining little bones or ossicles below the sacrum that are likewise fused together. A fall, sitting on a hard or narrow surface, degenerative joint changes or vaginal childbirth can cause tailbone pain.
The pain in the tailbone can be dull and achy, but it usually becomes sharper when performing particular tasks, such as sitting, rising from a seated posture to a standing position, or standing for an extended period of time.
Tailbone pain can be acute, occurring for a short period of time (normally fades away on its own in a matter of weeks or months), but if it does not go away, it becomes chronic. If your coccyx pain won't go away it may be as a result of different factors, and you should visit a doctor for diagnosis and possible treatments.
