Tailbone Injury Causes

Most tailbone injuries are caused by trauma to the coccyx area.

  • A fall onto the tailbone in the seated position, usually against a hard surface, is the most common cause of coccyx injuries.
  • A direct blow to the tailbone, such as those that occur during contact sports, can injure the coccyx.
  • The coccyx can be injured or fractured during childbirth.
  • Repetitive straining or friction against the coccyx (as happens in bicycling or rowing) can injure the coccyx.
  • Sometimes, the cause of coccyx injuries is unknown.
  • Less common causes of coccyx injuries include bone spurs, compression of nerve roots, injuries to other parts of the spine, local infections, and tumors.

Tailbone Injury Symptoms

  • Severe localized pain and tenderness may be felt in the tailbone area.
  • If the injury is traumatic, a bruise may be visible in this area.
  • The pain is generally worse when sitting for prolonged periods of time, or with direct pressure to the tailbone area.
  • Bowel movements and straining are often painful.
  • Some women may experience pain during sexual intercourse.
