Peripheral Artery Disease Symptoms: Leg Pain While Walking, Cold Feet and When to See a Doctor

Leg pain can be easy to brush off and blame on aging, sore muscles, arthritis, back problems or uncomfortable shoes. Cold feet may be chalked up to “poor circulation.” Numbness, heaviness or cramping in the legs may seem like something to wait out. However, these symptoms could be signs of peripheral artery disease, also called PAD.

Peripheral artery disease is a circulation problem that most often affects blood flow to the legs and feet. It’s one possible cause of what many people describe as poor circulation in the legs. PAD can be easy to miss because symptoms may come and go, only happen during walking or feel similar to other common problems.

In this article, we’ll explain the common symptoms of PAD, how they can feel different from ordinary leg pain, who may be at higher risk and when leg pain or cold feet should be checked by a doctor.

What Is Peripheral Artery Disease?

Peripheral artery disease (PAD) is a condition where narrowed or blocked arteries reduce blood flow to the limbs. It most often affects the legs and feet. In many cases, PAD is related to plaque buildup inside the arteries. This plaque can limit how much oxygen-rich blood reaches the leg muscles, especially during activity.

PAD is not just a leg problem, but a cardiovascular condition. Because it can be related to plaque buildup in the arteries, it may also be a sign that a person has a higher risk for other heart and vascular problems.

This is why leg symptoms should not always be ignored, especially if you also have high cholesterol, high blood pressure, diabetes, a smoking history or a personal history of heart disease or stroke.

Common PAD Symptoms

Peripheral artery disease doesn’t always cause obvious symptoms at first. Some people notice mild leg or foot changes for months before realizing they may be related to circulation. Not everyone with PAD has classic leg pain, so changes in foot temperature, wounds, skin color or walking tolerance can also be important.

Leg Pain or Cramping While Walking

One of the most common symptoms of PAD is leg pain, cramping, aching or fatigue that happens during walking or climbing stairs.

This discomfort may affect the:

• Calves
• Thighs
• Hips
• Buttocks
• Feet

PAD-related discomfort often starts during activity and improves after resting for a few minutes, which is a key distinction to remember. This activity-related pattern is sometimes called intermittent claudication, which means leg discomfort that starts with walking or exercise and improves with rest.

For example, someone may be able to walk a certain distance before calf pain starts. After stopping, the pain eases. When they begin walking again, the pain may return. This happens because the leg muscles need more blood flow during activity. If narrowed arteries cannot deliver enough blood, symptoms may appear.

Cold Feet or One Foot Feeling Colder Than the Other

Cold feet can happen for many reasons, but PAD can sometimes cause one foot or lower leg to feel colder than the other because of reduced blood flow.

This may be more concerning if the coldness is:

• New
• Persistent
• Worse on one side
• Paired with numbness, pain, color changes or slow-healing wounds

Numbness, Weakness or Heaviness in the Legs

PAD may not always feel like sharp pain. Some people describe their symptoms as:

• Heaviness
• Weakness
• Tired legs
• Numbness
• Aching
• Burning
• Cramping

These symptoms may be more noticeable during walking, exercise or while climbing up stairs. They can also overlap with neuropathy, sciatica, arthritis or vein problems, which is why a medical evaluation may be needed to understand the cause.

Slow-Healing Sores on the Feet or Legs

Slow-healing sores on the feet, toes or legs can be a more concerning sign of circulation problems. When blood flow is reduced, the body may have a harder time healing cuts, blisters, ulcers or wounds. For people with diabetes, this can matter even more, because diabetes can affect both circulation and nerve sensation.

You should contact a doctor if a sore:

• Is not healing
• Keeps coming back
• Appears to be getting worse
• Has increasing redness, swelling, drainage, pain or discoloration

Skin, Hair or Nail Changes

PAD can also cause visible changes in the legs or feet. These may include:

• Shiny skin on the legs
• Hair loss or reduced hair growth on the legs
• Slower toenail growth
• Pale, bluish or discolored skin
• Weak or difficult-to-feel pulses in the feet
• Feet or toes that look different from usual

These changes don’t automatically mean you have PAD, but they may give your doctor important clues about circulation.

PAD vs. Normal Leg Pain: How Can You Tell the Difference?

Many common problems can cause leg discomfort, including muscle strain, arthritis, sciatica, neuropathy and vein conditions, but there may be specific patterns you can look for that may be worth bringing to a doctor’s attention.

Muscle soreness often follows a workout, long walk or physical activity and gradually improves over time. Arthritis pain may be worse with certain joint movements. Sciatica may travel from the lower back into the leg and may be associated with numbness, tingling or certain spine positions.

PAD-related leg pain often has a different pattern. It may:

• Show up during walking or climbing stairs
• Happen after a similar amount of activity each time
• Improve after resting for a few minutes
• Return when walking starts again
• Affect the calves, thighs, hips or buttocks
• Come with coldness, numbness or foot changes

If you recognize these patterns, it’s important to bring that pattern to a doctor’s attention.

Who Is Most at Risk for PAD?

Peripheral artery disease is more likely in people with certain cardiovascular risk factors. You may have a higher risk of PAD if you have:

• A history of smoking
• Diabetes
• High cholesterol
• High blood pressure
• Older age
• A family history of vascular disease
• A personal history of heart disease
• A personal history of stroke
• Kidney disease
• Obesity or a sedentary lifestyle

Smoking and diabetes are especially important risk factors for PAD. People with multiple risk factors should be more cautious about new or recurring leg symptoms, even if the symptoms seem mild at first.

If you already know you have high cholesterol, high triglycerides, high blood pressure or diabetes, leg symptoms should be taken seriously as part of your overall heart and vascular health.

How Is PAD Diagnosed?

A doctor may start by asking about your symptoms, medical history and risk factors. They could ask questions such as:

• Where is the pain located?
• Does it happen during walking?
• How far can you walk before symptoms start?
• Does the pain improve with rest?
• Do you have cold feet, numbness or wounds?
• Do you have diabetes, high cholesterol or high blood pressure?
• Do you smoke or have a past smoking history?

A physical exam may include checking pulses in the feet and legs, looking at skin changes and comparing both sides of the body.

One common test for PAD is called the ankle-brachial index, or ABI. This test compares blood pressure in the ankle with blood pressure in the arm. If blood pressure is lower in the ankle, it may suggest reduced blood flow to the legs. Depending on your symptoms and exam findings, your doctor may also recommend blood tests or additional vascular testing.

Since PAD can be related to plaque buildup in the arteries, it may also point to a need for a broader cardiovascular risk evaluation. A doctor can review blood pressure, cholesterol, triglycerides, blood sugar, smoking history and other factors that can affect heart and vascular health. 

Can Peripheral Artery Disease Be Treated?

Peripheral artery disease can often be managed, especially when it is found early.

The right treatment depends on your symptoms, how much blood flow is affected and your overall health. Your doctor may recommend steps such as:

• Walking or supervised exercise therapy to help improve leg symptoms
• Quitting smoking, since smoking can make PAD worse
• Managing cholesterol and blood pressure to support heart and vascular health
• Managing diabetes, if it is part of your health history
• Medication, when appropriate, to help reduce cardiovascular risk or manage symptoms
• Referral to a vascular specialist, if symptoms are more serious or blood flow is severely reduced

For many people, PAD care is not just about the legs. It is also about protecting overall heart and circulation health.

Frequently Asked Questions About PAD Symptoms

What does PAD leg pain feel like?

PAD leg pain may feel like cramping, aching, heaviness, fatigue or discomfort in the calves, thighs, hips, buttocks or feet. It often happens during walking or climbing stairs and improves after resting for a few minutes.

Can PAD cause cold feet?

Yes, PAD can sometimes cause coldness in the feet or lower legs because blood flow is reduced. One foot feeling colder than the other may be especially important to mention to a doctor.

Is peripheral artery disease the same as poor circulation?

Peripheral artery disease is one possible cause of poor circulation in the legs and feet. However, people use “poor circulation” to describe many different symptoms, so it’s important to get evaluated instead of assuming the cause.

Can PAD symptoms come and go?

Yes. PAD symptoms may come and go, especially early on. Some people only notice symptoms when walking, exercising or climbing stairs. Symptoms may improve with rest and return with activity.

When should I worry about leg pain while walking?

You should talk with a doctor if leg pain happens repeatedly while walking, improves with rest or limits your usual activities. You should be especially cautious if you also have diabetes, high cholesterol, high blood pressure, a smoking history or known heart disease.

Is PAD related to cholesterol?

PAD is often related to plaque buildup in the arteries, and cholesterol can play a role in that process. Not everyone with high cholesterol has PAD, but cholesterol is one of the cardiovascular risk factors doctors may check when evaluating circulation symptoms.

Can PAD be diagnosed with a test?

One common test for PAD is the ankle-brachial index, or ABI. It compares blood pressure in the ankle and arm to help evaluate blood flow to the legs. Your doctor can decide whether ABI testing or other vascular testing is appropriate based on your symptoms and risk factors.

Can PAD be treated?

Yes. PAD can often be managed with the right medical care and lifestyle changes. Depending on your health, your doctor may recommend walking or supervised exercise therapy, help with cholesterol, blood pressure or diabetes management, medication or a referral to a vascular specialist.
