Many people realize that varicose veins can be unsightly, but did you know that they may also affect your sleep? If you suffer from varicose veins in Houston and have been diagnosed with restless legs syndrome (RLS), then continue reading to learn about the link between these 2 conditions.
Quick Answer: Varicose veins and restless legs syndrome (RLS) are separate conditions, but they often overlap. Faulty vein valves let blood pool in the legs, which can cause aching, heaviness, tingling and an urge to move that feels very similar to RLS, especially in the evening. When an ultrasound shows vein reflux, treating the faulty veins can ease restless leg symptoms for many patients, although it will not help RLS that comes from other causes such as low iron or nerve problems.

Varicose Veins and RLS Can Be Related
For some individuals, varicose veins are merely an aesthetic issue. For others, these veins cause symptoms like throbbing, itching, cramping, or achy, heavy, and painful feeling legs. If you have been diagnosed with RLS, then you may see that many of the symptoms of this condition overlap with those of having varicose veins.
RLS Can Have Secondary Causes
For most people, RLS is considered primary RLS, meaning that the cause is unknown. However, RLS can sometimes be the result of an underlying medical condition, which is referred to as secondary RLS. Some examples of these underlying conditions include varicose veins or venous insufficiency, pregnancy, kidney failure, and iron deficiency. When diagnosing you with RLS, your doctor should evaluate your body for the presence of varicose veins to determine if they may be part of the problem.
Addressing Varicose Veins May Relieve RLS Symptoms
If varicose veins or venous insufficiency are an underlying cause of your RLS, then seeing a vein specialist for treatment may provide you with some relief from your symptoms. In fact, research has demonstrated that most RLS patients who are treated with sclerotherapy for their varicose veins experience relief from their RLS symptoms. However, because varicose veins tend to recur, addressing your risk factors for varicose veins may be helpful in easing your RLS symptoms long-term.
There Are Several Treatment Options for Varicose Veins
Sclerotherapy, laser therapy, and endovenous ablation procedures are some examples of treatments for varicose veins. Sclerotherapy involves the injection of a chemical into the vein that causes it to shrink and disappear. Endovenous procedures close the vein from the inside with the use of a catheter.
What Restless Legs Syndrome Feels Like
Restless legs syndrome is a sensory and movement disorder. People describe it in many ways: crawling, pulling, buzzing, tingling, an itch deep inside the leg, or simply an urge to move that they cannot ignore. What ties these descriptions together is a pattern that doctors use to make the diagnosis.
- An urge to move the legs, usually with uncomfortable sensations inside them
- Worse at rest, when sitting in a car, watching television or lying in bed
- Relieved by movement, such as walking, stretching or rubbing the legs, at least while the movement lasts
- Worse in the evening or at night than earlier in the day
- Not explained by another condition alone, such as cramps, arthritis or positional discomfort
Because the symptoms peak at bedtime, RLS is often first noticed as a sleep problem. Patients tell us they lie down exhausted, then spend an hour getting up, pacing the hallway or shaking their legs before they can settle. The next day they feel tired and foggy, and that cycle can last for years before anyone looks at the veins.
How Varicose Veins Can Cause Restless Leg Symptoms
Leg veins depend on small one-way valves and on the squeezing action of the calf muscles to send blood back to the heart. When valves weaken, blood falls back down the leg and pools in the superficial veins. This is called venous reflux, and over time it raises the pressure in the lower leg.
That pressure does more than stretch the veins. It allows fluid to leak into the tissues and irritates the vein walls and the small nerves that run alongside them. The result is a mix of aching, heaviness, throbbing, burning and restlessness that tends to build as the day goes on and is most noticeable when you finally sit or lie down. In other words, vein disease can produce sensations that meet many of the features of RLS.
The overlap works both ways. Some people diagnosed with RLS turn out to have significant reflux that was never checked, while others with obvious varicose veins have true primary RLS that has nothing to do with their veins. The only way to tell is to look at the veins properly with ultrasound.
Why vein symptoms often peak at bedtime
During the day, walking keeps the calf muscle pump working and helps push blood up the leg. By evening, hours of standing or sitting have let blood and fluid collect in the lower legs. When you finally lie still, the distraction of activity is gone and the built-up pressure and swelling become noticeable. Many patients find that the first half hour in bed is the worst, and that getting up to walk briefly helps, which is exactly why vein-related discomfort is so easily mistaken for RLS.
Clues that the veins may be involved
- Visible varicose veins, bulging clusters or spider veins around the ankle
- Aching, heaviness or swelling that worsens after standing
- Symptoms that ease when you raise your legs or wear compression stockings
- Ankle swelling, brown skin discoloration or itchy skin over the lower leg
- Night cramps in the calves in addition to restlessness
RLS vs Vein Symptoms vs Other Leg Conditions
Several common conditions cause uncomfortable legs at night. The table below shows the features we use in clinic to separate them. Many patients have more than one.
| Condition | Main sensation | When it is worst | What eases it | Key test |
|---|---|---|---|---|
| Primary RLS | Urge to move with crawling or tingling feelings | Evening and night, at rest | Walking or moving the legs | Clinical history; iron studies |
| Venous insufficiency | Aching, heaviness, throbbing, swelling | End of the day, after standing | Leg elevation, compression | Venous duplex ultrasound |
| Nocturnal leg cramps | Sudden, painful, hard muscle spasm | Night, often waking you | Stretching the muscle | History and exam |
| Peripheral arterial disease | Calf pain with walking; foot pain at night in severe cases | During exercise | Rest; dangling the foot in severe cases | Ankle-brachial index |
| Peripheral neuropathy | Numbness, burning, pins and needles in the feet | Often constant, worse at night | Little relief from movement | Nerve testing |
Who Should Have Their Veins Checked for RLS?
Not everyone with restless legs needs a vein evaluation, but in our experience it is worth considering if you have any of the clues above, or if RLS treatment has not helped as much as expected. A vein check makes particular sense for:
- People whose restless legs began or worsened during or after pregnancy
- Those who work long hours standing, such as nurses, teachers and retail or restaurant staff
- Anyone with a family history of varicose veins
- Patients with RLS in one leg more than the other, which is less typical of primary RLS
- People taking RLS medicines whose doses keep needing to be increased
It is also important to check iron. Low iron stores in the body, measured with a ferritin blood test, are a well-known contributor to RLS. Your primary care doctor can order this, and correcting low iron is often part of the plan alongside any vein treatment.
How We Evaluate Restless Legs and Vein Disease
At Premier Vein & Vascular Center, the goal of the first visit is to find out whether your veins are part of the problem, not to assume they are.
- Focused history. We ask when the symptoms occur, what they feel like, what eases them, how they affect your sleep, and about pregnancies, clots, medicines and family history.
- Examination. We look for varicose and spider veins, swelling, skin changes around the ankle and pulses in the feet, with you standing as well as lying down.
- Venous duplex ultrasound. Our accredited vascular lab maps the superficial and deep veins and measures reflux. This shows whether a leaking saphenous vein or branch is likely to be contributing to your symptoms.
- A clear plan. If reflux is present, we explain which veins are involved and how treatment may help. If the veins are healthy, we tell you that too, so you and your primary care doctor or sleep specialist can focus on other causes.
Treatment Options When Veins Are Contributing to RLS
Treatment begins with simple measures and moves to procedures when the ultrasound shows significant reflux. Most vein procedures today are done in the office under local anesthesia, and patients walk out the same day.
Conservative care
Graduated compression stockings worn during the day help many people with venous symptoms, and some notice calmer legs at night as a result. Regular walking, calf raises, leg elevation in the evening and avoiding long periods of sitting all support the calf muscle pump.
Closing the leaking veins
When a main superficial vein is refluxing, it can be closed from the inside with radiofrequency ablation, laser ablation or non-thermal ablation using a medical adhesive or microfoam. Blood then reroutes through healthy veins. Each leg typically takes under an hour, and most patients return to normal activity within a day or two.
Treating the branches
Remaining bulging branches can be removed through tiny nicks with ambulatory phlebectomy or closed with sclerotherapy. Treating the source vein first and the branches second usually gives the most lasting result.
Patients often ask whether they will be able to stop their RLS medicine. That depends on how much of the restlessness was vein-related. Some people notice clear improvement in their nights, others a partial change, and those with primary RLS may need ongoing care from their primary care doctor or a sleep specialist. Any change to medicines should be made with the prescribing doctor.
Habits That Calm Restless Legs at Night
Whatever the cause, these everyday steps often help:
- Take a short walk in the evening rather than sitting for hours before bed
- Stretch the calves and hamstrings before lying down
- Raise your legs for 15 to 20 minutes in the evening if vein symptoms are part of the picture
- Limit caffeine, alcohol and nicotine, especially later in the day
- Keep a regular sleep schedule and a cool, dark bedroom
- Ask your doctor whether any of your medicines, such as some antihistamines or antidepressants, could be worsening symptoms
A simple symptom diary for two weeks, noting what time the restlessness starts, how long you stood or sat that day and what helped, is very useful to bring to your appointment.
Call 911 or seek emergency care if you notice:
- Sudden swelling, pain, warmth or redness in one leg, which may be a deep vein thrombosis
- Chest pain, sudden shortness of breath or coughing up blood
- A cold, pale or numb foot
- Bleeding from a varicose vein that does not stop with firm pressure and leg elevation

Frequently Asked Questions
Can varicose veins cause restless legs at night?
Yes, they can contribute. Venous reflux raises pressure in the lower leg and can cause aching, heaviness and an urge to move that is often worst in the evening. An ultrasound can show whether faulty veins are likely to be part of your symptoms.
Will vein treatment cure my restless leg syndrome?
It depends on the cause. When reflux is driving the symptoms, closing the faulty veins often brings meaningful relief. If RLS is primary or linked to low iron or nerve problems, vein treatment alone is unlikely to resolve it.
How do I know if my RLS is caused by my veins?
Clues include visible varicose veins, ankle swelling, aching that builds through the day and symptoms that ease with leg elevation or compression. A venous duplex ultrasound is the test that confirms whether reflux is present.
Do compression stockings help restless legs?
They can help when vein disease is part of the problem, because they reduce pooling and swelling during the day. They are less likely to help RLS that is unrelated to the veins.
What blood test should I have for restless legs?
A ferritin test, which measures the body’s iron stores, is commonly recommended because low iron is a known contributor to RLS. Your primary care doctor can order it and advise on iron replacement if needed.
What kind of doctor should I see for restless legs and varicose veins?
Your primary care doctor or a sleep specialist can evaluate RLS in general. If you also have varicose veins, swelling or heavy legs, a vein specialist can check for reflux with ultrasound and treat it if found.
Can you have restless legs without visible varicose veins?
Yes. Reflux can occur in veins that sit too deep to see, so legs can look fairly normal on the surface. If you have aching, heaviness or swelling along with restlessness, an ultrasound can check for hidden reflux.
