Painless swelling of the feet and ankles is a common problem, especially among older people.

Injury or surgery involving the leg, ankle, or foot can also cause swelling. Swelling may also occur after pelvic surgery, especially for cancer.
Long airplane flights or car rides, as well as standing for long periods of time, often lead to some swelling in the feet and ankles.
Swelling may occur in women who take estrogen, or during parts of the menstrual cycle. Most women have some swelling during pregnancy. More severe swelling during pregnancy may be a sign of preeclampsia , a serious condition that includes high blood pressure and swelling.

Home Care
Some tips that may help reduce swelling:
- Put your legs on pillows to raise them above your heart while lying down.
- Exercise your legs. This helps pump fluid from your legs back to your heart.
- Follow a low-salt diet, which may reduce fluid buildup and swelling.
- Wear support stockings (sold at most drugstores and medical supply stores).
- When traveling, take breaks often to stand up and move around.
- Avoid wearing tight clothing or garters around your thighs.
- Lose weight if you need to.
Never stop taking any medicines you think may be causing swelling without first talking to your health care provider.

Lower leg edema - illustration
Painless swelling of the feet and ankles is a common problem, particularly in older people. Most of the time swelling can be relieved by elevating the legs above the heart while lying down and avoiding sitting or standing without moving for prolonged periods of time. Although swelling of the feet and ankles can be a minor problem, it can also be an indication of more serious illnesses such as heart failure, renal failure, or liver failure.
