Poor circulation in the legs means blood is not flowing through your legs the way it should. It can come from narrowed arteries, from faulty veins, or from both at once. The cause matters, because the treatment for an artery problem is different from the treatment for a vein problem.
If your legs hurt when you walk, if your feet are always cold, or if a small wound on your foot heals slowly, poor circulation may be the reason. These symptoms deserve an evaluation, not a wait and see approach.
At Vein and Knee Pain Vascular Group in New York City, we find the source of the problem first, then treat it at the source.
This guide explains what poor circulation in the legs is, what causes it, how it is diagnosed, and when you should see a vascular doctor.
Key Takeaways
- Poor circulation in the legs means reduced blood flow, usually from narrowed arteries, faulty veins, or both.
- Leg pain when walking, cold feet, numbness, skin color changes, and wounds that heal slowly are the most common warning signs.
- Peripheral artery disease (PAD) is one of the main causes. Smoking is its leading risk factor.
- Diagnosis starts with a physical evaluation and may include an ABI ultrasound, a duplex ultrasound, or an angiogram.
- Treatment depends on the cause. Artery problems are treated with minimally invasive endovascular procedures. Vein problems are treated with vein closure treatments.
- A vascular doctor treats blood vessel problems in the legs. A cardiologist treats the heart. Our guide on whether a vascular doctor is the same as a cardiologist explains the difference.
- Rest pain, a wound that does not heal, signs of infection, or worsening pain need prompt evaluation.
What Is Poor Circulation in the Legs?
Poor circulation in the legs means less blood is reaching your leg muscles, skin, and feet than your body needs. Blood carries oxygen and nutrients. When flow drops, the tissues in your legs do not get enough of either one.
Poor circulation is not one disease. It is a sign that something is wrong with the blood vessels in your legs. The problem can sit in the arteries, which carry blood down to your legs, or in the veins, which carry blood back up to your heart.
Two Directions of Blood Flow
Arteries carry oxygen rich blood from your heart down to your legs and feet. When an artery narrows, less blood gets through. The muscles and skin below the narrowing do not get enough oxygen.
Veins carry blood back from your legs to your heart. Small valves inside the veins keep blood moving in one direction. When those valves fail, blood pools in the legs instead of flowing upward.
Both problems cause poor circulation, but they feel different and they are treated differently. That is why an evaluation matters. Guessing at the cause can lead to the wrong treatment.
Poor Circulation vs Varicose Veins: What Is the Difference?
Varicose veins and poor circulation are related, but they are not the same thing. Varicose veins are one visible sign of a vein problem. Poor circulation is the wider problem of reduced blood flow, and it can come from arteries, veins, or both.
| Artery Problem (PAD) | Vein Problem (Venous Insufficiency) | |
|---|---|---|
| What goes wrong | Arteries narrow, so less blood reaches the legs | Valves fail, so blood pools in the legs |
| Main symptom | Leg pain or cramping when walking, which eases with rest | Heaviness, swelling, aching, and visible veins |
| Skin and feet | Cold feet, pale or bluish skin, shiny skin, slow growing toenails | Swelling around the ankles, skin color changes, itching |
| Wounds | Wounds on the feet or toes that heal slowly or not at all | Sores that come from swelling and pressure |
| Common cause | Smoking, diabetes, high cholesterol, high blood pressure, aging | Faulty valves, standing for long hours, pregnancy, family history |
| How it is found | ABI ultrasound and angiogram | Duplex ultrasound |
| How it is treated | Minimally invasive endovascular treatment | Vein closure treatments such as VenaSeal and Varithena |
Some patients have both problems at once. That is common, and it is one more reason a full evaluation matters before any treatment is planned.

Signs of Poor Circulation in Your Legs
Poor circulation does not always start with pain. Some signs are easy to miss, and some are easy to blame on age or tired legs. The signs below are the ones we hear most often from patients in our New York clinic.
Leg Pain or Cramping When Walking
Leg fatigue and cramping in the hips, thighs, or calves while walking, climbing stairs, or exercising is one of the most common signs. This pain is called claudication. It usually eases when you stop and rest, then returns when you walk again.
Pain that persists after exercise can be a sign of more severe disease. If walking distance keeps getting shorter, tell your doctor. Do not assume it is normal aging.
Cold Feet and Skin Changes
A temperature difference between one leg or foot and the other can be a sign of poor circulation. One foot may feel cool to the touch while the other feels normal. The skin on the feet may also feel cool.
Skin color changes are another sign. Skin may look pale, bluish, or reddish. Shiny skin on the legs or feet can also appear when blood flow is reduced.
Wounds That Heal Slowly or Not at All
Wounds on the feet or toes that heal slowly or do not heal at all are a serious warning sign. When blood flow is low, the skin cannot repair itself properly. Even a small cut or blister can turn into a chronic sore.
Frequent infections in the feet or legs can also be a sign. If a wound keeps coming back, or if it gets worse instead of better, it needs an evaluation soon.
Swelling, Heaviness, and Aching
Swelling in the legs or ankles, a feeling of heaviness, and a dull ache are common when veins are the problem. Blood pools in the lower legs because the valves cannot push it upward against gravity.
Swelling that is worse at the end of the day, or after standing for a long time, often points to a vein problem. Visible bulging veins may be present too, but poor circulation can exist even when no veins are visible.
Numbness, Tingling, and Weakness
Leg numbness or weakness can be a sign of poor circulation. Some patients feel tingling in their feet or toes. Others feel an aching or burning sensation in their feet or toes at rest.
These symptoms can overlap with nerve problems and joint problems, so they need a proper evaluation. Numbness alone does not prove the cause. An ultrasound or angiogram can show whether blood flow is the problem.
What Causes Poor Circulation in the Legs?
Poor circulation has several causes, and more than one can be present at the same time. The two main causes are peripheral artery disease and venous insufficiency. Risk factors make both more likely.
Peripheral Artery Disease (PAD)
Peripheral artery disease, or PAD, is a condition in which the arteries in the legs narrow. Fatty deposits build up inside the artery walls, and blood flow drops. The American Heart Association estimates that more than 8 million Americans have PAD.
PAD often develops slowly. In its early stage, it may cause no symptoms at all. As it advances, walking becomes painful. In its later stages, it can cause pain at rest and wounds that do not heal.
Our PAD treatment page explains the stages of PAD and the minimally invasive treatments we offer for it.
Venous Insufficiency and Faulty Valves
Venous insufficiency means the valves inside the leg veins do not close properly. Blood flows backward and pools in the lower legs. Pressure builds inside the veins, and the veins enlarge and twist into varicose veins.
Faulty valves can run in families. Standing or sitting for long hours, pregnancy, and extra weight can all add pressure to the veins. Over time, the valves weaken and the circulation problem grows.
Risk Factors That Make It Worse
Several risk factors raise the chance of poor circulation in the legs. Smoking is the leading risk factor for PAD. Type 2 diabetes, high blood pressure, and high cholesterol also damage blood vessels over time.
Obesity and aging add to the risk as well. A family history of vascular disease matters too. If you have one or more of these risk factors and you notice leg symptoms, an evaluation is worth your time.
How Is Poor Circulation Diagnosed?
Diagnosis starts with a consultation. At our clinic, Dr. Amir Salem reviews your medical history and performs a physical evaluation. He looks at your legs and feet, checks your pulses, and asks about your symptoms and your risk factors.
Imaging tests then show exactly where the problem is and how severe it is. The test depends on whether the problem looks arterial, venous, or both.
ABI Ultrasound
An ABI ultrasound, also called an ankle brachial index test, compares blood pressure in your ankle with blood pressure in your arm. A lower reading in the ankle can mean narrowed arteries in the legs.
The test is painless and takes only a few minutes. It is often the first test used when PAD is suspected, and it can also be used to follow how the condition changes over time.
Angiogram Mapping
An angiogram is an imaging test that maps the arteries in your legs. Contrast dye and X-ray images show where an artery is narrowed or blocked, and how severe the narrowing is.
Angiogram mapping helps your doctor plan treatment. It shows which artery needs attention and which minimally invasive technique fits that spot.
Duplex Ultrasound
A duplex ultrasound uses sound waves to show blood flow through your veins and arteries. It can show faulty valves, blood moving in the wrong direction, and veins that are not working properly.
Duplex ultrasound is the main test for venous insufficiency and varicose veins. It maps which veins have reflux and whether a vein closure treatment fits your case.
How Is Poor Circulation Treated in New York?
Treatment depends on the cause. There is no single treatment for poor circulation, because an artery problem and a vein problem need different approaches. Your doctor will explain your options after your evaluation, before anything is scheduled.
Minimally Invasive Treatment for Artery Problems
When PAD is the cause, treatment aims to restore blood flow through the narrowed artery. At our clinic, PAD is treated with minimally invasive endovascular procedures. These include endovascular therapy, atherectomy, laser atherectomy, balloon angioplasty, and stenting.
These procedures are done through a small access point, with no large incision and no hospital stay. Most patients go home the same day. Treatments are often used together, depending on what the angiogram shows.
Vein Closure Treatments for Vein Problems
When faulty veins are the cause, treatment aims to close the diseased vein so blood reroutes to healthy veins. Two treatments we offer are VenaSeal and Varithena.
VenaSeal uses a medical adhesive to seal the problem vein shut, with no heat. The reported closure rate is 94.6 percent at five years, and the procedure takes approximately 45 to 60 minutes.
Varithena is an FDA-approved microfoam therapy that is injected into the affected vein under ultrasound guidance. It is done in under 30 minutes.
To compare the two options, read our VenaSeal closure procedure page and our Varithena foam treatment page.
Treating the Source, Not Just the Symptoms
Many patients are told to manage leg pain with medication, compression, or injections. Our approach is different. We look for the vascular source of the problem first, then treat the affected vein or artery with precision.
Walking and movement can help circulation, and your doctor may discuss activity as part of your plan. But walking alone does not fix a narrowed artery or a faulty valve. When a blockage or a failed valve is the cause, treatment at the source is what restores flow.
What Type of Doctor Treats Poor Circulation in Legs?
A vascular doctor treats poor circulation in the legs. Vascular doctors specialize in diseases of the blood vessels outside the heart and brain, including arteries and veins in the legs. They diagnose circulation problems and treat them with minimally invasive procedures.
This is different from a cardiologist, who specializes in the heart. Cardiologists may identify vascular disease, but they usually refer patients to a vascular doctor for specialized care. If your symptoms involve the legs or veins, a vascular doctor is usually the right first step.
Our guide on what a vascular doctor does explains the role, the training, and the treatment approach in detail.

When Should You See a Doctor Right Away?
Most leg symptoms should be evaluated soon, but some signs need prompt attention. Do not wait if you notice any of the following.
- Pain in your feet or toes at rest, especially pain that wakes you at night.
- A wound on your foot or toe that does not heal, or a wound that is getting worse.
- Signs of infection, such as redness, warmth, swelling, or discharge from a wound.
- Skin color changes, or a foot that turns pale, blue, or very red.
- Pain that keeps getting worse, or walking distance that keeps getting shorter.
- Severe pain, or bleeding from a vein or wound that will not stop. These need urgent care.
Poor circulation symptoms can overlap with vein, nerve, and joint problems. Only an evaluation can tell which one is causing your symptoms. The earlier the cause is found, the more options you usually have.
Frequently Asked Questions About Poor Circulation in Legs
Is poor circulation the same as peripheral artery disease?
No. Poor circulation is a general term for reduced blood flow in the legs. Peripheral artery disease is one specific cause of it. Faulty veins can also cause poor circulation. An evaluation shows which one is behind your symptoms.
Can poor circulation in the legs be reversed?
It depends on the cause. A narrowed artery or a faulty valve does not fix itself, but treatment can restore better flow. Endovascular procedures can open a narrowed artery, and vein closure treatments can reroute blood to healthy veins. Your doctor will explain what is realistic in your case.
What type of doctor treats poor circulation in legs?
A vascular doctor treats poor circulation in the legs. Vascular doctors specialize in blood vessel problems outside the heart. At our clinic, that care is led by Dr. Amir Salem, MD, a board-certified vascular and interventional radiologist.
Is poor circulation in legs dangerous?
It can be. Poor circulation can lead to wounds that do not heal, infections, and loss of mobility. In severe cases, it can threaten the limb. That is why rest pain, non-healing wounds, and worsening symptoms need prompt evaluation.
Does walking help poor circulation?
Walking and movement can help circulation, and your doctor may discuss activity as part of your plan. But walking alone does not fix a narrowed artery or a faulty valve. If a blockage or a failed valve is the cause, treatment at the source is needed.
What is the first test for poor circulation in legs?
It depends on your symptoms. An ABI ultrasound is often the first test when narrowed arteries are suspected. A duplex ultrasound is the main test when faulty veins are suspected. An angiogram maps the arteries when treatment is being planned.
Does insurance cover poor circulation treatment in New York?
Coverage varies by diagnosis, medical necessity, insurance plan, and authorization requirements. We accept Medicare, Medicaid, Aetna, Cigna, Blue Cross Blue Shield, and UnitedHealthcare, plus 25 or more other plans. We verify your insurance benefits before anything is billed. For prices, see our varicose vein treatment cost guide.
Can varicose veins cause poor circulation?
Yes. Varicose veins are a sign that the valves inside the leg veins are not working properly. When valves fail, blood pools in the legs instead of flowing back to the heart. That is poor circulation from a vein problem, and it is treated by closing the diseased vein.
Final Thoughts
Poor circulation in the legs is a warning sign, not a diagnosis. It can come from narrowed arteries, faulty veins, or both. Leg pain when walking, cold feet, numbness, skin changes, and wounds that heal slowly are all reasons to get evaluated.
The right step is a consultation with a vascular doctor who can find the source of the problem. At Vein and Knee Pain Vascular Group in New York City, Dr. Amir Salem reviews your history and examines your legs.
He may order a duplex ultrasound or angiography to map the problem. Then he explains your options and builds a personalized treatment plan. We verify your insurance before anything is billed, so you know what you may owe before treatment is scheduled.
