Peripheral Artery Disease: 6 Leg Signs That Point to It, and Why 1 in 5 People Have None

Leg pain that starts when you walk and stops when you rest has a name and a five minute test. About 1 in 5 people with it report no symptoms at all.

Leg pain that arrives on the walk to the mailbox and leaves when you stop is not a wear and tear story. It is a plumbing story with a five minute test.

Peripheral artery disease is narrowing in the arteries feeding the legs. The muscle asks for more blood, the artery cannot deliver, and the leg complains until you stand still.

Below are the six signs, the ankle test to ask for by name, and why the quietest version matters most.

1
The Signs · 6

Six things the legs do when the arteries narrow

NHLBI lists the symptoms of peripheral artery disease, and it leads with the walking pattern because that is the one people recognise.

Six are worth memorising, because five of the six are not pain.

  1. Pain that comes with walking and goes with rest. NHLBI says pain, aching, heaviness or cramping in the legs on walking or stairs that goes after rest is called intermittent claudication and is the most common symptom. Often the calf, sometimes the buttock, thigh or foot.
  2. Toenails and leg hair that stop growing. NHLBI names both, and Mayo Clinic lists slow growing toenails and hair loss on the legs too. Tissue short of blood stops spending it on growth.
  3. One foot colder than the other. NHLBI says one foot may feel colder than the other, and Mayo Clinic says coldness in the lower leg or foot is telling especially compared with the other side.
  4. Colour changes in the foot or leg. NHLBI says the foot or leg may become pale, discoloured or blue, and Mayo Clinic adds shiny skin and skin colour changes.
  5. Weakness, numbness or pins and needles. NHLBI says leg weakness or numbness may make you feel off balance or make walking harder, and that pins and needles can appear in the leg or foot.
  6. Sores that will not heal. NHLBI says sores or wounds on the toes, feet or legs may heal slowly or not at all, and may become infected. Mayo Clinic lists non healing sores too. Not a wait and see sign.

That figure is why this article exists. A quiet case carries the same cardiovascular risk as a loud one.

The Test

An arm cuff, an ankle cuff, and an answer

Cleveland Clinic says the ankle brachial index compares blood pressure in your arm with blood pressure at your ankle, that providers use it to screen people with risk factors, and that it is usually the first test when symptoms point this way.

Before the cuffs go on, the exam is simple. Cleveland Clinic says the provider examines your bare feet and feels the pulse at several points in the leg.

NHLBI says pain that comes with walking and goes with rest is the most common sign.

If the index comes back normal and suspicion stands, Cleveland Clinic names the next tests: vascular ultrasound, pulse volume recording, and CT angiogram.

None of it requires a hospital stay. The first test is two cuffs and a few minutes.

No matter the symptoms, everyone with peripheral artery disease shares the same high risk of cardiovascular disease.

The Drivers

What narrows the artery in the first place

Mayo Clinic says peripheral artery disease is usually a sign of atherosclerosis, a buildup of fats, cholesterol and other substances in and on the artery walls that narrows them and blocks blood flow.

It is the same process that narrows the arteries of the heart and brain, which is why Mayo Clinic lists stroke and heart attack among the complications.

The rest of Mayo Clinic's risk list is familiar: family history of the disease, heart disease or stroke, diabetes, high blood pressure, high cholesterol, obesity and smoking.

Its prevention list is plain: do not smoke, eat foods low in sugar, trans fats and saturated fats, exercise with your care team's guidance, keep a healthy weight, manage blood pressure, cholesterol and diabetes, sleep well and control stress.

Mayo Clinic names the treatment trio in one line: exercising, eating healthy foods, and not smoking.

Three leg pain beliefs that cost people a leg

Three ideas keep this condition undiagnosed, and each has a published answer.

Sore legs after a walk are just age. Age is a risk factor, not an explanation. Mayo Clinic says painful cramping in the hips, thighs or calves after walking or climbing stairs is a symptom, and NHLBI says that pattern is the most common symptom of the condition.

No pain means no problem. NHLBI says about 1 in 5 people who have peripheral artery disease report no symptoms and more than half have nontypical ones, while everyone with the condition shares the same high cardiovascular risk. Cleveland Clinic says the ankle brachial index is used to screen people with risk factors, symptoms or not.

Walking makes it worse, so rest the leg. Mayo Clinic names exercise as part of the treatment, alongside eating healthy foods and not smoking, and says to check with your care team about what type and how much. Cleveland Clinic names structured exercise therapy among the treatments that prevent complications like limb loss.

📋Your Coach's Recommendations
1
Time the pain, do not just rate it.
NHLBI says the telling feature is the pattern: pain, aching, heaviness or cramping that starts with walking or stairs and goes away after rest. Write down how far you get before it starts and how long it takes to settle. That single sentence is the most useful thing you can hand a doctor.
2
Ask for the ankle brachial index by name.
Cleveland Clinic says it compares the blood pressure in your arm with the blood pressure at your ankle, that it is used to screen people with risk factors, and that it is usually the first test when symptoms suggest peripheral artery disease. Ask for a bare foot exam and pulse check at the same visit.
3
Treat it as a whole body finding, not a leg problem.
NHLBI says everyone with it shares the same high cardiovascular risk, and Mayo Clinic lists stroke and heart attack among the complications. Bring blood pressure, cholesterol, diabetes and smoking to the same appointment.

To your health,

This article is education, not medical advice. Mayo Clinic says to make an appointment if you have leg or arm pain or other symptoms of peripheral artery disease. NHLBI says that without treatment it may cause sores, infections and even loss of a limb, and that leg and foot pain at rest is a sign of severe disease.

Frequently Asked Questions

What does peripheral artery disease feel like?
NHLBI says the most common symptom is intermittent claudication: pain, aching, heaviness or cramping in the legs that comes on with walking or climbing stairs and goes away after rest, most often in the calf but sometimes the buttock, thigh or foot.
Can you have it without any symptoms?
Yes. NHLBI says about 1 in 4 people have the common symptoms, more than half have nontypical ones, and about 1 in 5 report no symptoms at all, while everyone with the condition shares the same high risk of cardiovascular disease.
What test diagnoses it?
Cleveland Clinic says the ankle brachial index, comparing blood pressure in your arm with blood pressure at your ankle, is usually the first test. If it is normal and suspicion remains, it names vascular ultrasound, pulse volume recording and CT angiogram as next steps.
Who is most at risk?
Mayo Clinic names a family history of peripheral artery disease, heart disease or stroke, diabetes, high blood pressure, high cholesterol, obesity, smoking, and increasing age, especially after 65, or after 50 for anyone with risk factors for atherosclerosis.
Should I keep walking if it hurts?
Ask your care team first. Mayo Clinic includes exercise in the treatment of peripheral artery disease and says to check what type and how much is right for you, and Cleveland Clinic names structured exercise therapy among the treatments used to prevent complications.
