Swelling in your legs and ankles can be easy to brush off at first. Maybe your shoes feel tighter by the afternoon, or you notice a sock line that takes a while to fade. When the puffiness keeps coming back day after day, though, it is worth paying attention to what your body may be trying to tell you.

Persistent leg swelling has several possible causes, and getting to the bottom of it starts with a proper evaluation. At Great Lakes Medical Imaging (GLMI), we care for patients across Buffalo and Western New York, including Williamsville, Cheektowaga, Orchard Park, and Cambria in Niagara County. When swelling may be tied to your veins, our painless ultrasound studies help your provider understand what is happening beneath the surface.

Why Leg and Ankle Swelling Should Not Be Ignored

Swelling, also called edema, happens when fluid builds up in the tissues of your legs, ankles, or feet. A little puffiness after a long day on your feet is common. The kind that deserves a closer look is the kind that sticks around, returns regularly, or affects one leg more than the other.

It is important to understand that leg and ankle swelling can have several possible causes. Swelling can be related to the veins, the heart, the kidneys, certain medications, or other factors. Because of this, persistent swelling should be evaluated by a provider who can sort out the overall cause. At GLMI, our venous studies assess the vein component specifically, giving your provider one important piece of the larger picture.

How Your Veins Can Lead to Swelling

One common vein-related cause of leg swelling is venous reflux, also known as venous insufficiency. To understand it, it helps to picture how your veins are supposed to work. The veins in your legs carry blood back up toward your heart, working against gravity the whole way. Tiny one-way valves inside those veins open to let blood move upward, then close to keep it from sliding back down.

When those valves do not work well, blood can pool in the legs instead of flowing efficiently back toward the heart. Over time, that pooling raises pressure in the leg veins, and fluid can leak into the surrounding tissue. The result is swelling that tends to be worse by the end of the day and may ease overnight when your legs are elevated. You can learn more on our veins and venous disease page.

Symptoms That May Warrant a Varicose Vein Screening

Swelling rarely shows up entirely on its own. When the veins are involved, it often travels with other signs. The following symptoms may suggest it is time to consider a varicose vein screening:

• Leg pain, aching, or cramping
• Burning or itching of the skin
• Leg or ankle swelling, especially toward the end of the day
• A heavy feeling in the legs
• Visible varicose veins
• Skin discoloration or changes in skin texture
• Open wounds or sores
• Restless legs

If you recognize your own legs in several of these descriptions, that is a reasonable reason to ask about an evaluation. None of these symptoms means you should panic, and many people live with mild versions for years. Still, knowing the cause puts you in a better position to make decisions about your comfort and your leg health.

The First Step: A Simple, Painless Ultrasound

When the goal is to understand the vein component of your swelling, the first step is simply an ultrasound. This study is often called a venous insufficiency study or a venous Doppler study, and it is safe and painless. There are no needles and no radiation involved.

During the exam, a technologist moves a small handheld device, called a transducer, over the skin of your leg. It uses sound waves to create a live picture of your veins and to show how blood is moving through them. This lets the team see whether the valves are allowing blood to flow backward, which is the hallmark of venous reflux. You can read more about how this technology works on our ultrasound page, and you can explore the full range of services on our imaging services overview.

The results give your provider clear information about what is happening in your leg veins. From there, you and your provider can talk through next steps with real answers rather than guesswork. If you are wondering whether this is right for you, you can contact GLMI with any questions before you schedule.

When Swelling Is Due to Venous Reflux: Treatment Options

If your evaluation shows that your swelling and symptoms are due to venous reflux, the good news is that effective treatment is available, and it does not require a hospital stay. At GLMI, we treat varicose veins with the ClosureFast radiofrequency ablation (RFA) procedure.

RFA is a minimally invasive treatment that uses radiofrequency heat to seal the affected vein. Once that troublesome vein is closed, your blood naturally reroutes to nearby healthy veins, so sealing one poorly functioning vein does not harm your circulation. In most cases, the procedure also reduces the appearance of visible varicose veins, so many patients notice both relief of symptoms and a cosmetic improvement.

For many people, cost is a natural concern. The ClosureFast RFA procedure is covered by most insurances, which makes treatment accessible for patients who qualify. Your provider and our team can help you understand what to expect and walk you through the details that apply to your situation.

When to Have Your Veins Evaluated

So how do you decide it is time? A good rule of thumb is to take action when swelling is persistent, when it keeps returning, or when it comes along with the symptoms listed above. Swelling that is steadily getting worse or that is paired with skin changes or sores is a clear signal to seek an evaluation rather than wait.

Remember that an evaluation is not a commitment to any particular treatment. It is simply a way to get clear, reliable information about your legs. Because swelling can come from the veins, the heart, the kidneys, medications, or other sources, working with a provider ensures that nothing important is overlooked.
