Sciatica
Sciatica — shooting, burning, or radiating pain that travels from the lower back down through the buttock and into one leg — affects many pregnant women, particularly in the second and third trimesters.
Common Causes
- Growing uterus and baby press directly on the sciatic nerve
- Pelvic instability from relaxin hormone allows shifting that irritates the nerve
- Poor posture adaptation to the growing belly shifts the spine
- Baby's position — when the baby is in a posterior or low position, pressure on the sciatic nerve increases
- Weight gain increases overall spinal and pelvic load
Remedies That May Help
Pigeon Pose (Modified)
A modified supine pigeon stretch opens the piriformis muscle, reducing sciatic nerve compression.
Warm or Cold Compress
Apply to the lower back or buttock where the nerve is compressed — alternate cold (inflammation) and warm (muscle relief) as needed.
Swimming or Water Exercise
Buoyancy in water removes weight from the spine and pelvis, providing significant relief.
Prenatal Massage
A therapist trained in prenatal massage can release piriformis muscle tension compressing the sciatic nerve.
Maternity Support Belt
A support belt redistributes abdominal weight and reduces pelvic pressure on the sciatic nerve.
Physiotherapy
A pelvic floor physiotherapist or prenatal physical therapist can provide targeted exercises and manual therapy.
When to Call Your Doctor

- Pain after a fall or trauma
- Pain in both legs simultaneously
Frequently Asked Questions
Is sciatica pain dangerous in pregnancy?
Sciatica is painful but not dangerous. It poses no direct risk to the baby. However, numbness, weakness, or loss of bowel/bladder control warrants urgent evaluation.
What does pregnancy sciatica feel like?
It typically feels like a sharp, shooting, burning, or electric pain starting in the lower back or buttock and radiating down one leg to the knee, calf, or foot.
Does sciatica during pregnancy mean a difficult birth?
No — sciatica does not predict labor complications. If the baby is pressing on the nerve, delivery naturally resolves the pressure.
When does pregnancy sciatica start?
It most commonly begins in the second trimester (weeks 14–27) when the uterus grows large enough to press on the nerve, and may worsen in the third trimester.
Will sciatica go away after giving birth?
In most cases, sciatica caused by uterine pressure resolves within weeks of delivery. Persistent sciatica postpartum may need physiotherapy.
