Pelvic Pain in Mid and Late Pregnancy
Patient may experience difficulty with walking, standing, going down stairs, turning in bed, and, in severe cases, immobility.
Pathophysiology:
By the influence of relaxin and progesterone, the fibrocartilaginous symphysis pubic joint relaxes by 2-3 mm in normal pregnancy to widen the pelvis before delivery. If this is increased, it causes pelvic girdle instability and pain.
Examination shows:
- Tenderness over symphysis pubis and sacroiliac joints.
- Reduced hip movement range.
Management:
- Consult an obstetric physiotherapist for advice on posture and gentle exercises.
- Pelvic support.
- Paracetamol and Codeine.
- Crutches, walking frame, or wheelchairs in severe cases.
- Avoid heavy lifting and prolonged standing.
- When getting out of the car or turning in bed, avoid hip abduction by keeping knees together.
- During labor, avoid leg separation and excessive hip abduction.
Symptoms are usually resolved postpartum with high probability of recurrence in subsequent pregnancies.
