Tailbone pain â pain that occurs in or around the bony structure at the bottom of the spine (coccyx) â can be caused by trauma to the coccyx during a fall, prolonged sitting on a hard or narrow surface, degenerative joint changes, or vaginal childbirth.
Minor falls and trauma to the tailbone can result in bruising and severe force can inflict a hairline crack or simple fracture. Hairline cracks can appear anywhere in the tailbone, but often form at the coccyx tip or at the fused natural seams of the coccygeal vertebrae.
