Painless swelling of the feet and ankles is a common problem, especially among older people.
What causes Pedal edema?
Foot, leg, and ankle swelling is common with the following situations:
Being overweight Blood clot in the leg Increased age Leg infection Veins in the legs that cannot properly pump blood back to the heart Injury or surgery involving the leg, ankle, or foot can 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 (also called toxemia), a serious condition that includes high blood pressure and swelling.
Swollen legs may be a sign of heart failure, kidney failure, or liver failure. In these conditions, there is too much fluid in the body.
Certain medications may also cause your legs to swell:
Antidepressants, including MAO inhibitors (such as phenelzine and tranylcypromine) and tricyclics (such as nortriptyline, desipramine, and amitriptyline) Blood pressure medicines called calcium channel blockers (such as nifedipine, amlodipine, diltiazem, felodipine, and verapamil) Hormones like estrogen (in birth control pills or hormone replacement therapy) and testosterone Steroids.
Your doctor will take a medical history and do a thorough physical examination, paying special attention to your heart, lungs, abdomen, lymph nodes, legs, and feet.
Your doctor will ask questions like the following:
- What body parts swell? Your ankles, feet, legs? Above the knee or below?
- Do you have swelling at all times or is it worse in the morning or evening?
- What makes your swelling better?
- What makes your swelling worse?
- Does the swelling get better when you raise your legs?
- What other symptoms do you have?
- Diagnostic tests that may be done include the following:
The treatment will be aimed at the cause of the swelling. Diuretics may be prescribed to reduce the swelling, but they can have side effects. Home treatment for benign causes of leg swelling should be tried before drug therapy.
When to seek urgent medical care?
Call 911 if:
- You feel short of breath.
- You have chest pain, especially if it feels like pressure or tightness.

- When traveling, take breaks often to stand up and move around.
- Avoid wearing tight clothing or garters around your thighs.
