Tailbone Pain
Tailbone (coccyx) pain is a common pregnancy complaint, especially in the second and third trimesters. Relaxin loosens the joints around the coccyx, and the growing uterus shifts posture, putting additional strain on the area.
Common Causes
- Relaxin hormone loosens the sacrococcygeal joint (where the tailbone meets the sacrum)
- Shifted center of gravity changes how weight is distributed onto the tailbone
- Prolonged sitting puts direct pressure on the coccyx
- Baby's position may place pressure on the coccyx from inside
- Prior tailbone injury is more symptomatic during pregnancy
Remedies That May Help
Coccyx (Donut) Cushion
A wedge-shaped or donut cushion with a cutout relieves pressure directly on the tailbone when sitting.
Change Positions Frequently
Avoid prolonged sitting or standing — alternating positions prevents sustained coccyx loading.
Warm Compress
A warm compress or warm bath relaxes the muscles surrounding the coccyx.
Pelvic Floor Physiotherapy
A physiotherapist can release tight coccyx-associated muscles and improve alignment.
Avoid Hard Surfaces
Sit on padded chairs or use a cushion on hard seats.
Lean Forward When Sitting
Leaning slightly forward when sitting transfers weight from the coccyx to the sit bones.
When to Call Your Doctor
- Tailbone pain is severe and disabling
- Pain extends down both legs or causes numbness (possible nerve involvement)
- Tailbone pain after a fall or direct injury
- Pain with bowel movements that is worsening
- Pain that doesn't improve after delivery
Frequently Asked Questions
Can a baby break your tailbone during birth?
A baby can occasionally fracture or dislocate the tailbone (coccyx) during a difficult delivery, especially with forceps or prolonged pushing. This is relatively rare.
What is the best sitting position for tailbone pain in pregnancy?
Leaning slightly forward so weight rests on the sit bones (ischial tuberosities) rather than the coccyx is best. A coccyx cushion supports this position.
Will tailbone pain resolve after birth?
For most women, coccyx pain improves significantly within weeks to months after delivery as relaxin levels drop and posture normalizes.
Can tailbone pain cause problems during labor?
Significant coccyx flexibility is actually helpful during labor, as the coccyx moves to widen the birth canal. In most cases, tailbone pain does not complicate delivery.
Is tailbone pain the same as lower back pain?
No — tailbone pain is specifically at the very tip of the spine (coccyx), just above the anus. Lower back pain is higher up, in the lumbar spine. Both can occur in pregnancy.
