Alternative names: swelling of the ankle, feet, or leg; peripheral edema; ankle swelling; foot swelling; leg swelling; edema, peripheral

Definition: Abnormal build-up of fluids in ankle and leg tissues. See also swelling, overall.

Considerations: Painless swelling of the feet and ankles is a common problem, particularly in older people. It may affect both legs and may include the calves or even the thighs. Because of the effect of gravity, swelling is particularly noticeable in the lower legs. When squeezed, the fluid will move out of the affected area and may leave a deep impression for a few moments. Swelling of the legs is many times related to systemic causes (for example, heart failure, renal failure, or liver failure).

Common causes:

long airplane flights or automobile rides menstrual periods (for some women) sunburn generalized allergy prolonged standing injury or trauma to the ankle or foot venous insufficiency (varicose veins) pregnancy (mild to severe swelling) environmental

burns insect bite or sting starvation or malnutrition

medical treatments

body fluid overload infiltration of an IV site extremity surgery

medications

estrogens and progestin oral contraceptives blood pressure-lowering drugs certain antidepressants (such as Nardil) estrogen - oral long-term corticosteroid therapy nifedipine testosterone

diagnostic tests

venogram

congestive heart failure glomerulonephritis Note: There may be other causes of ankle, feet, and leg swelling. This list is not all inclusive, and the causes are not presented in order of likelihood. The causes of this symptom can include unlikely diseases and medications. Furthermore, the causes may vary based on age and gender of the affected person, as well as on the specific characteristics of the symptom such as specific location, quality, time course, aggravating factors, relieving factors, and associated complaints. Use the Symptom Analysis option to explore the possible explanations for ankle, feet, and leg swelling, occurring alone or in combination with other problems.

Home care: Elevate the legs above the heart while lying down. Avoid sitting or standing without moving for prolonged periods of time. Avoid putting anything directly under the knees when lying down and don't wear constricting clothing or garters on the upper legs. Exercising the legs causes the fluid to work back into the veins and lymphatic channels so that the swelling goes down. The pressure applied by elastic bandages or support stockings can help reduce ankle swelling. A low-salt diet may help reduce fluid retention and decrease the ankle swelling.

Call your health care provider if:

ankle swelling persists or worsens after the above measures have been taken.

What to expect at your health care provider's office: The medical history will be obtained and a physical examination performed. Medical history questions documenting ankle, feet, and leg swelling in detail include:

time pattern

aggravating and relieving factors

other

What other symptoms are also present? The physical examination may include emphasis on the heart, lungs, kidneys, and legs. Diagnostic tests that may be performed include:

blood tests such as a CBC or blood chemistry (Chem-20) ECG chest X-ray or extremity X-ray Intervention: The specific treatment will be directed at whatever underlying cause is found. Diuretics (fluid pills) may be prescribed. These are effective in reducing the swelling but have some side effects. Home treatment for benign causes of leg swelling should be tried before drug therapy under medical supervision. After seeing your health care provider: You may want to add a diagnosis related to ankle, feet, and leg swelling to your personal medical record.
