Pelvic girdle pain is one of the most common musculoskeletal problems experienced during pregnancy and early motherhood. Many women describe it as a sharp or catching pain around the front of the pelvis, the groin, the buttock or deep in the lower back. It often appears suddenly and makes simple movements unexpectedly difficult.
Unlike general pelvic pain, pelvic girdle pain is a mechanical joint problem. The joints that connect the spine to the pelvis and the pubic bone at the front become sensitive to load. As the body adapts to pregnancy and changing posture, these joints stop transferring force smoothly through the body. Everyday movements begin to overload one side of the pelvis instead of sharing the load between both legs.
This is why many women feel fine sitting or lying down, but experience pain when moving.
Women rarely describe pelvic girdle pain as a constant ache. Instead it appears during movement. The most common description is pain that “catches” or “grabs” when changing position.
During pregnancy the body becomes more flexible to allow growth and birth. Hormonal changes soften ligaments while abdominal muscles lengthen and the centre of gravity shifts forward.
These changes are normal and helpful. Problems occur when the stabilising muscles around the pelvis cannot control the extra movement. The pelvis then loses its ability to transfer load efficiently between the legs and the trunk.
Instead of force spreading evenly across the pelvis, one joint takes too much load. Repeated daily activities then irritate the joint and surrounding tissues.
After birth the same issue can persist because muscles remain inhibited and movement habits developed during pregnancy continue.
Pelvic girdle pain most commonly begins:
during the second trimester
in late pregnancy as movement becomes heavier
after delivery when activity levels increase again
when returning to exercise
after lifting or carrying a baby frequently
Some women feel it gradually increasing, while others notice a sudden sharp onset during a normal movement like turning in bed.
Pelvic girdle pain is strongly linked to asymmetrical movements where weight goes through one leg.
This includes rolling, stepping, lunging, pushing and twisting. The joint is not damaged, but it becomes sensitive when repeatedly loaded unevenly.
Small changes to movement patterns often reduce pain within days because they restore balanced load through the pelvis.
Strategies commonly recommended include:
keeping knees together when rolling in bed
taking smaller steps when walking
sitting to get dressed
avoiding twisting when carrying
using pillows to support the legs during sleep
pacing activity rather than pushing through pain
Many women are surprised how quickly symptoms settle once the joint is no longer repeatedly irritated.
Physiotherapy focuses on restoring the pelvis’ ability to transfer load again rather than simply stretching or resting the area.
Treatment typically involves identifying which movements overload the joint and retraining the muscles that stabilise the pelvis during daily activity. Real-time feedback and guided exercises teach the body how to control movement without bracing or guarding.
Manual therapy may be used to calm irritated joints and muscles, followed by specific stability retraining so the improvement lasts.
Most importantly, treatment shows you how to move comfortably through pregnancy and safely return to normal activity afterwards.
Pelvic girdle pain does not mean damage and it does not mean you must stop being active. When the correct muscles begin sharing load again, symptoms usually improve quickly.
Some women feel relief within a few sessions, while others improve gradually as strength and confidence return. Early treatment often prevents worsening pain later in pregnancy and reduces postnatal problems.
If pelvic pain makes walking, sleeping or daily tasks difficult, assessment is recommended. Persistent pain rarely resolves by simply resting because the issue relates to movement control rather than inflammation.
Early guidance helps keep you active throughout pregnancy and makes recovery after birth smoother.
Pelvic girdle pain is very responsive to the right treatment approach. Understanding how your body moves allows treatment to be tailored so you can stay mobile, sleep comfortably and care for your baby with confidence.
