Summary

Sharp, shooting pelvic pain during the third trimester is a common condition often referred to as Symphysis Pubis Dysfunction (SPD) or "Lightning Crotch." As the body prepares for childbirth, hormonal changes and the baby's position can cause the pelvic joints to become unstable or misaligned, leading to significant discomfort during movement.

Most likely causes

  • Symphysis Pubis Dysfunction (SPD): Relaxin hormones cause the ligaments holding the pelvic bone together to become too stretchy, leading to instability.
  • Pelvic Girdle Pain (PGP): Uneven movement or misalignment of the sacroiliac (SI) joints at the back of the pelvis.
  • Fetal Positioning: The baby’s head pressing against specific nerves (like the obturator or sciatic nerves) as they drop lower into the pelvis.
  • Round Ligament Strain: Sharp pains triggered by the stretching of the ligaments supporting the uterus.
