Restless, Aching Legs at Night: Could It Be a Vein Problem?

Published September 6th, 2026 by Great Lakes Medical Imaging

You finally settle into bed after a long Western New York day, and just as you start to relax, your legs will not cooperate. They feel achy, heavy, or restless, and you find yourself shifting positions or wanting to move them to feel better. If this sounds familiar, you are not alone, and it is worth understanding what might be behind it.

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. This article looks at one possible reason for restless, aching legs at night, a vein issue called venous reflux, while being clear that several other causes exist. We will explain how the veins can be evaluated and when it makes sense to talk with a provider.

Why Legs Can Feel Achy or Restless at Night

Leg discomfort that shows up in the evening or at night can come from many different sources. Your legs work hard all day, and once you finally lie down, you may notice sensations that the busyness of the day kept in the background. Aching, heaviness, cramping, and a restless feeling are all common complaints, and they do not all share the same cause.

Because the reasons can vary so much, it helps to think of nighttime leg discomfort as a signal rather than a diagnosis. The signal is worth attention, especially if it happens often, disrupts your sleep, or comes with other changes in your legs.

One Possibility: Venous Reflux

One reason legs can feel achy, heavy, or restless, especially in the evening or at night, is a vein problem called venous reflux, sometimes referred to as venous insufficiency. Your leg veins contain small one way valves that are supposed to keep blood moving upward, back toward your heart. When those valves do not work well, blood can pool in the legs instead of flowing the way it should.

That pooling can contribute to uncomfortable sensations, including the heavy, tired, or restless feeling that many people notice once they are off their feet for the day. To learn more about how the veins work and what can go wrong, our overview of veins and venous disease is a helpful place to start.

Signs That May Point to a Vein Issue

Vein problems do not always look the same from one person to the next. Some people have very visible veins, while others mostly notice how their legs feel. The following symptoms are among those that may warrant a varicose vein screening:

Leg pain, aching, or cramping
Burning or itching of the skin
Leg or ankle swelling, especially at 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 several of these sound familiar, it does not automatically mean you have a vein problem, but it does mean the question is worth raising. You can contact GLMI with questions about evaluation, or bring the topic to your next visit with your provider.

An Important Caveat: Other Causes Exist

Here is a point we want to be very clear about. Restless and aching legs at night are not always a vein problem. There are several other possible causes, and a vein issue is only one of them.

One important example is restless legs syndrome. This is a distinct neurological condition, and it is not the same as vein disease. People with restless legs syndrome often feel a strong urge to move their legs, frequently along with uncomfortable sensations. Even though it can sound similar to what a vein problem causes, the underlying issue is different. Other medical conditions can also lead to leg restlessness or aching at night.

Because these causes can overlap and feel alike, it really does take a provider to help sort out what is happening. GLMI's role is specifically to evaluate the vein component when that is an appropriate part of the picture.

How GLMI Evaluates the Veins

If you and your provider decide it makes sense to look at the veins, the first step is simple. It is an ultrasound study, sometimes called a venous insufficiency study or a venous Doppler study. This test is safe and painless, and it does not involve any needles or radiation.

During the study, a technologist uses ultrasound to look at how blood is moving through your leg veins and to check whether the valves are working the way they should. The information from this study gives your provider a clear picture of whether venous reflux is part of what is causing your symptoms. You can learn more about the range of tests we offer on our imaging services page.

An ultrasound does not replace a conversation with your provider. Instead, it gives that conversation a solid foundation, so any next steps are based on real information about your veins.

What Happens If Venous Reflux Is the Cause

When symptoms turn out to be due to venous reflux, GLMI treats varicose veins with a procedure called ClosureFast radiofrequency ablation, often shortened to RFA. It is a minimally invasive treatment that uses radiofrequency heat to gently seal the affected vein. Once that vein is sealed, blood naturally reroutes to nearby healthy veins, which can help relieve the symptoms the troubled vein was causing.

For many patients, the fact that this procedure is minimally invasive is reassuring. It is also covered by most insurances, which is one less thing to worry about. Whether this treatment is right for you depends on your individual situation, and that is always a decision you make together with your care team after the veins have been evaluated.

When to Talk With a Provider

It is a good idea to bring up nighttime leg symptoms with a provider if they happen often, interfere with your sleep, or come with swelling, visible veins, skin changes, or sores. Even if the cause turns out not to be your veins, that conversation can point you toward the right kind of help.

Living in Buffalo and Western New York means staying active through every season, from shoveling the driveway in winter to walking and gardening once the warm weather arrives. Comfortable legs make all of that easier, so there is no reason to put up with discomfort if something can be done about it.
