About 2/3 of women experience swelling in their legs and ankles. During pregnancy, the fluid in your body increases to nourish you and your baby. The fluid can accumulate in your legs and ankles as a result of increased blood flow and pressure on the pelvic veins from the uterus. This accumulation of fluid is called edema and results in the swelling and pain in the legs and ankles. At Pregnancy Pain Relief, we decrease the pressure the uterus places on the pelvic veins as well as massage the fluid in the legs back into circulation to decrease the swelling.
