Pubic bone pain is becoming an increasingly common complaint in pregnancy. This can be due to pre-existing disease that has been exacerbated during pregnancy or be peculiar to pregnancy itself. There are many physiological changes in the pelvis during pregnancy that can account for this symptom. These include the increase in mechanical stress on the pelvis due to the increasing weight, the increase in laxity of the ligaments and fibrocartilaginous joints as a result of the hormonal changes in pregnancy, and the changes in posture that are associated with advancing pregnancy.
