Pelvic pain during pregnancy and postpartum period is common. Pubic separation is a physiologic phenomenon caused by pregnancy and delivery. It's an aetiology of pregnancy and postpartum pain requiring a specialized management in case of severe pain. We report the case of a 34-year-old multiparous woman suffering from severe pubic symphysis pain after twin delivery by vaginal approach, with extraction support, under epidural analgesia. Pubic symphysis separation was diagnosed according both to the clinical symptoms and to the radiology. A local anesthetic infiltration was performed twice to substantially relieve the patient.
