As your uterus expands, you may feel aches and pains in the back, abdomen, groin area, and thighs. Many women also have backaches and aching near the pelvic bone due the pressure of the baby's head, increased weight, and loosening joints. Some pregnant women complain of pain that runs from the lower back, down the back of one leg, to the knee or foot. This is called sciatica (SYE-AT-ick-uh). It is thought to occur when the uterus puts pressure on the sciatic nerve.
