Rib Pain at 24 Weeks Pregnant

Rib pain is very common in the third trimester as the growing uterus pushes up against the rib cage. Baby kicks to the ribs and diaphragm can cause sharp, brief pain.

👶 What's Happening at Week 24

Your baby is now the size of a cantaloupe.

  • The fetus now has a chance of survival if born prematurely (with NICU care).
  • Lungs are developing branches of the respiratory tree.
  • The inner ear develops fully — baby can sense being upside down.

🔬 Why You're Experiencing Rib Pain at Week 24

  • Expanding uterus pushes upward against the lower ribs and diaphragm
  • Baby's kicks and movements directly impact the ribs and intercostal muscles
  • Rib cage flares outward to accommodate expanding lungs and uterus
  • Postural changes and rounded shoulders increase rib cage tension
  • The intercostal muscles (between the ribs) stretch and become more sensitive

💊 Relief Tips for Week 24

1
Good PostureSitting tall with shoulders back creates more space in the chest cavity and reduces rib compression.
2
Change PositionsIf baby is lodged against your ribs, changing position (moving, rolling over, or a gentle nudge) often shifts the baby.
3
Raise Your Arms OverheadStretching arms up momentarily creates more space in the torso and can relieve rib pressure.
4
Avoid SlouchingSlouching compresses the space between the uterus and ribs, worsening discomfort.
5
Warm CompressA warm compress on the affected rib area can ease muscle tension.

Frequently Asked Questions

Why does my baby kick me in the ribs so much?

In the third trimester, the baby has less room and their feet often end up tucked under the mother's ribs. Kicks can be very forceful in this position.

Can pregnancy cause rib fractures?

True rib fractures from uterine pressure are extremely rare. Rib pain in pregnancy is almost always soft-tissue and muscle-related.

When does rib pain start in pregnancy?

It most commonly begins in the third trimester (weeks 28–40) as the uterus reaches the level of the rib cage.

Does rib pain go away when the baby drops?

Yes — when the baby's head engages in the pelvis (lightening), upward pressure on the ribs and diaphragm is relieved, often improving rib pain and breathing.
