Coccyx injury
Tailbone trauma is an injury to the small bone at the lower tip of the spine.

Causes
Backward falls onto a hard surface, such as a slippery floor or ice, are the most common cause of this injury.

- Relieve pressure on the tailbone by sitting on an inflatable rubber ring or cushions.
