Edema (slight swelling) is normal and usually begins in the last few months of pregnancy. It usually occurs in the legs and ankles. It may be worse in the summer months. You may want to elevate your legs while you are sitting or laying down. If you elevate your legs while you sleep, the swelling usually disappears by morning. Let your health care provider know if you have swelling in your hands or face because that can be a symptom of another problem. 

Do not take any medication (such as "water pills") for swelling unless prescribed by your health care provider. 

Swollen veins are called varicose veins. During your pregnancy you may develop varicose veins in your legs or near your vulva and vagina. Varicose veins during pregnancy are due to the pressure of your growing uterus on your veins. They are usually not serious but may cause aching and soreness. 

Tips to relieve swelling and varicose veins: 

• Do not sit or stand for long periods of time.
• Elevate your legs whenever possible.
• Rest in your bed on your left side.
• Lie down with your legs raised on a small stool or several pillows. You may want to also elevate your hips if you have developed varicose veins in your vaginal area.
• Do not wear stockings or socks with tight elastic around the legs.
• Wear support pantyhose.
• Exercise regularly, especially walking, swimming, or riding an exercise bike.
• Do not cross your legs when you are sitting.
