Swollen Ankles After Flying? You May Need a Leg Vein Ultrasound

December 17, 2025

Swollen ankles after a flight are often dismissed as harmless – but should they be? The answer: not always. If your swelling is persistent, painful, or only in one leg, it could be a sign of a more serious condition like deep vein thrombosis (DVT) or poor circulation. In cases like this, a leg vein ultrasound is the most effective way to assess what’s really going on below the surface.

 

What Is a Leg Vein Ultrasound – and Why Might You Need One?

A leg vein ultrasound is a safe, non-invasive imaging scan that uses sound waves to assess blood flow in your leg veins. It’s commonly used to detect blood clots, valve issues, and other circulation problems that might be causing your legs or ankles to swell.

While some swelling after long flights or extended periods of sitting is normal, persistent or one-sided swelling can be a red flag. Conditions like deep vein thrombosis (DVT) or chronic venous insufficiency can lead to complications if left untreated – and often go unnoticed without a proper scan.

 

Why Do My Ankles Swell After Flying?

Swollen ankles after flying is a common concern, especially on long-haul trips. The lack of movement while seated for hours can slow down blood flow in the legs, increasing the risk of fluid retention and in more serious cases, blood clots. Some people also experience swollen feet and ankles after flying due to underlying vein issues they might not be aware of. Age, weight, pregnancy, certain medications, or a family history of clotting disorders can all raise your risk.

If you notice your ankles are swollen after a plane ride and the swelling doesn’t go down within a few hours, or is paired with pain, warmth, or redness, it’s time to seek medical advice – and potentially book a leg vein ultrasound.

 

When Is Swelling a Sign of Something Serious?

If you’re experiencing:

  • Swelling in just one leg
  • New or worsening swelling after a period of rest
  • Accompanying pain, redness, or warmth
  • Swollen ankles in old age that seem unusual or sudden

… it could be more than just fluid retention. These are classic signs of poor circulation or possible deep vein thrombosis.

In fact, swollen lower legs, especially in one leg only, may require further investigation. A Doppler ultrasound of the legs can help detect blood flow issues early and often before symptoms escalate into more serious health concerns.

 

How Can a Leg Vein Ultrasound Help?

A leg vein ultrasound gives your doctor a clear picture of how well blood is flowing through the veins in your legs. It can:

  • Confirm or rule out DVT
  • Detect chronic venous insufficiency
  • Assess for varicose veins or venous valve failure
  • Identify areas of reduced circulation

For those wondering how to improve circulation in legs or experiencing recurring swollen ankles after flying, a scan is the first step in understanding the cause and getting effective treatment. You don’t need a hospital visit to access this. At Capri Ultrasound, we offer fast, high-quality leg vein ultrasounds right here on the Isle of Capri, Gold Coast, in a comfortable outpatient setting.
