Swollen Feet

The podiatrists at Podobrace explain more about the condition of swollen feet on this page. Most people experience swollen feet at some point. If your shoes feel tight, especially at the end of a warm day, it’s a clear sign. In most cases, this is nothing serious and the swelling usually goes away on its own. However, if the swelling persists, it could be a sign of an underlying issue. That’s why it’s understandable that you may have questions. Below, we outline the main causes of swollen feet, along with practical solutions for each. Our podiatrists have also selected several products that can help reduce swelling in your feet.

Common causes of swollen feet

There are many reasons why your feet may become swollen. Below are the most common causes:

Foot injury
A foot injury, such as a sprained ankle, can lead to significant swelling. A sprain often results from the ankle twisting inward, damaging the surrounding ligaments. This may cause partial or full tears, along with bruising around the area.

Pregnancy
Pregnant women, especially those over 34 years old and in the later stages of pregnancy, often experience swelling in the feet. This is due to decreased kidney efficiency, which slows down fluid elimination.

Chronic venous insufficiency (CVI)
This condition occurs when veins in the legs struggle to return blood to the heart. It is often caused by weak connective tissue around the veins or may occur after a blood clot.

Cellulitis (wound infection)
Cellulitis is a bacterial infection of the skin. It may result from a minor wound, insect bite, or scratch that becomes infected, leading to swelling in the feet.

Thrombosis
Thrombosis may result from long periods of inactivity, wearing a cast, genetic factors, certain medications, or lack of movement. It involves a blockage in the veins, often due to a blood clot. Some medications can also cause swelling as a side effect. Additionally, heat can cause blood to pool in the vessels, increasing pressure and swelling.

Lymphedema
This is caused by an excessive buildup of lymphatic fluid and proteins in the tissues. It results from a disrupted balance between fluid intake and drainage. Heart, kidney, or liver conditions can also lead to fluid retention in the feet due to reduced function in these organs.

Treatments for swollen feet

Below are suggested treatments based on the underlying cause:

Foot injury
See your doctor or visit the emergency room. Apply a cold pack or ice to the area as soon as possible. Wrapping the area can also help. Swelling usually decreases after a few days.

Chronic venous insufficiency (CVI)
Surgical removal, laser therapy, or injection treatment may improve blood flow, but these are often last-resort options. You can also manage CVI with regular physical activity (walking, swimming, cycling), wearing compression stockings, maintaining a healthy weight, and elevating your legs when sitting.

Pregnancy
Regular movement can improve blood circulation. Compression stockings can help reduce fluid buildup. Leg massages are also helpful. Podobrace offers specially designed insoles and compression socks that can be used during pregnancy and in general cases of swelling.

Cellulitis
Limit standing and walking. Let the wound heal and elevate your legs with pillows while lying down. This will help reduce fluid accumulation and swelling should go down gradually.

Thrombosis
If your medication is causing swelling, talk to your doctor about alternatives. It's important not to adjust or stop medication without professional advice.

Lymphedema
Specially trained physical therapists, known as lymphedema therapists, play a key role in managing this condition. We strongly recommend contacting one if your swelling is due to lymphedema.
