Neuropathy vs Poor Circulation: Why Are Your Feet Cold?

Neuropathy and poor circulation both cause cold, numb feet, but they start in different places. Neuropathy is nerve damage: feet feel cold, burn or tingle, often worse at night. Poor circulation, usually peripheral artery disease (PAD), is reduced blood flow: calf pain when walking that eases with rest, and a foot that is truly cold to the touch.

Telling neuropathy vs poor circulation apart matters more as the weather turns. Cold makes both more noticeable, and they call for different next steps. If your symptoms already feel worse this season, our guide on whether cold weather makes neuropathy worse covers the nerve side in detail. The NeuropathyHealthGuide editorial team built this comparison in September 2026 from the NIDDK and NHLBI patient pages and the peer-reviewed reviews linked below. We are not doctors. Use this page to sort clues before your doctor visit, not instead of it.

What is the difference between neuropathy and poor circulation?

Neuropathy is a nerve problem and poor circulation is a blood flow problem. Peripheral neuropathy is damage to the nerves that carry feeling from your feet and hands, and it is very common: up to one half of people with diabetes have it, according to the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK). Poor circulation in the legs usually means peripheral artery disease, where plaque narrows the arteries and reduces blood flow. The National Heart, Lung, and Blood Institute (NHLBI) estimates that more than 8 million Americans aged 40 and older have PAD.

One is a wiring problem, the other a plumbing problem. For the full nerve picture, start with what peripheral neuropathy is and what causes neuropathy in the feet and legs.

Neuropathy vs poor circulation: side-by-side comparison

The fastest way to separate neuropathy from poor circulation (PAD) is timing, location and what a doctor can measure. The table uses the symptom lists published by the NIDDK for neuropathy and the NHLBI for PAD.

Two cautions. Symptoms overlap: the NHLBI notes that PAD can also cause leg weakness or numbness, and even a pins-and-needles feeling, so no single sensation settles the question. And many people with PAD do not fit the textbook picture. Only about 1 in 4 people with PAD have the common, textbook symptoms, more than half have nontypical symptoms, and about 1 in 5 report no symptoms at all, according to the NHLBI symptoms page.

Why do my feet feel cold when they are warm to the touch?

Feet that feel icy to you but warm to someone else's hand are a clue that points toward nerve damage (peripheral neuropathy), not the blood supply. A 2025 review of diabetic neuropathy in the Diabetes & Metabolism Journal lists "altered perception," a change in how cold and warm sensations are felt, among the symptoms of nerve damage, along with cold or hot sensations in the feet.

The logic: small nerve fibers in the skin sense temperature, and damaged fibers can report "cold" from skin that is normal. With PAD, the skin really is cooler because less warm blood reaches it.

Treat this as a pointer, not a verdict: a warm foot does not rule out PAD. Ask a family member to compare both feet with the back of their hand, and tell your doctor what they found. The early signs of nerve damage are covered in our list of neuropathy symptoms and early warning signs.

Walking pain vs night pain: the timing clue

Timing is the most useful clue for telling neuropathy from poor circulation. PAD classically causes pain, aching, heaviness or cramping in the legs that comes on when walking or climbing stairs and goes away after rest, a pattern called intermittent claudication, which the NHLBI describes as the most common PAD symptom. Neuropathy symptoms, by contrast, are often worse at night, according to the NIDDK.

Put simply:

• Pain that starts after a predictable distance of walking and stops when you stand still for a few minutes fits circulation.
• Burning or tingling that shows up in bed, when your feet are doing nothing fits nerves.

One exception: in severe PAD, pain can appear in the leg and foot at rest. The NHLBI calls this critical limb ischemia. Rest pain from PAD is not a reason to wait and see.

Walking is not the enemy. A 2017 Cochrane review of exercise for intermittent claudication found high-quality evidence that exercise programs improve both pain-free and maximum walking distance in people fit for exercise. For the nerve side, see does walking help neuropathy and our exercises for neuropathy in the feet. Ask your doctor which kind of program suits you before you start.

Warning signs of poor circulation that need a doctor soon

Signs of peripheral artery disease (PAD) such as leg pain at rest, sores that do not heal or a foot that turns pale or blue should not wait for a routine checkup. The NHLBI lists these as signs of PAD, and several point to advanced disease:

• Calf, thigh or buttock pain when walking that stops with rest (claudication)
• Pain in the leg or foot while resting, a sign of severe PAD
• Sores or wounds on the toes, feet or legs that heal slowly or do not heal
• A foot or leg that turns pale, discolored or blue
• One foot noticeably colder than the other
• Toenails and leg hair that stop growing
• Weak pulses in the legs, which your doctor checks during the exam

A foot that suddenly becomes cold, pale or blue and painful is different from slow, months-long symptoms. A sudden loss of blood flow to a limb, called acute limb ischemia, is described as an emergency condition in a 2018 review in Cardiovascular Diabetology. In that situation, call 911 or go to the emergency room.

The NHLBI adds that PAD in the legs may mean plaque in the arteries to the heart and brain too, which raises the risk of heart attack and stroke.

Having neuropathy and poor circulation at the same time

Yes, you can have neuropathy and poor circulation at the same time, and it is common in diabetes. The 2018 Cardiovascular Diabetology review reports that lower-extremity arterial disease is 2 to 4 times more frequent in people with type 2 diabetes than in the general population. The same review warns that diabetic neuropathy may hide the symptoms of arterial disease, so a person may have poor circulation without the warning pain.

That is the trap: numb feet may not feel claudication or a blister turning into a wound. The review also notes that neuropathy and calcified arteries can make the ankle-brachial index less reliable in diabetes. So if you already know you have one condition, do not use it to rule out the other. Our comparison of diabetic neuropathy vs peripheral neuropathy explains how diabetes fits into the larger nerve picture.

Tests that tell neuropathy and poor circulation apart

Doctors tell neuropathy and poor circulation apart with different tests, and most are quick office tests. For circulation, the ankle-brachial index (ABI) is usually the first: it compares blood pressure at the ankle and the arm. According to the NHLBI's diagnosis page, a healthy ABI is 1.00 or greater, and a resting ABI below 0.90 suggests PAD.

Circulation tests:

• Ankle-brachial index (ABI): a blood pressure cuff and a small ultrasound device. Below 0.40 signals severe PAD.
• Toe-brachial index (TBI): used when the ankle arteries are stiff. A TBI below 0.7 is abnormal.
• Exercise ABI and 6-minute walk test: show how much walking brings on symptoms.
• Doppler ultrasound: locates narrowed or blocked areas and measures blood flow.

Nerve tests:

• Monofilament test: a thin nylon strand pressed on the foot to see whether you feel it. The American Diabetes Association's 2017 position statement on diabetic neuropathy recommends it every year for people with diabetes.
• Tuning fork: checks whether you feel vibration at the big toe, as described by the NIDDK.
• Temperature or pinprick testing: checks the small fibers that carry heat, cold and pain.
• Nerve conduction studies and electromyography (EMG): the ADA says these are rarely needed, except when symptoms are atypical, the diagnosis is unclear or another cause is suspected.

Blood tests may also be ordered to rule out other causes of nerve damage, such as low vitamin B12 or thyroid problems.

What this page cannot tell you

No home test diagnoses peripheral neuropathy or peripheral artery disease. Feeling your own pulse, comparing foot temperatures or timing your calf pain can help you describe symptoms to your doctor, but none of them replaces an ABI or a nerve exam. The 2018 Cardiovascular Diabetology review notes that even a doctor's pulse check has weak diagnostic performance on its own, which is why measured tests exist. We cannot tell you which condition you have, or whether you have both.

No supplement treats PAD. "Circulation" supplements are marketed hard to people searching for cold feet. The best-studied example, ginkgo biloba, was reviewed by Cochrane across 14 trials and 739 participants. The 2013 review concluded there is no evidence that ginkgo has a clinically significant benefit for people with peripheral arterial disease. PAD care runs through your doctor, and the NHLBI advice centers on quitting smoking, staying active and managing diabetes, blood pressure and cholesterol.

On the nerve side, if your doctor confirms peripheral neuropathy, some people look at nutrient support alongside medical care. No supplement cures or reverses neuropathy, and the research on the best-studied ingredients is mixed. We lay out that evidence, including the parts that cut against the products, in our comparison of neuropathy supplements and our Arialief review. None of that applies to poor circulation.

Frequently asked questions

How can I tell if cold feet are from neuropathy or poor circulation?

Look at timing and touch, then confirm with a doctor. Nerve-related cold feet often come with burning or tingling, affect both feet, and bother you more at night. Circulation-related cold feet tend to come with calf pain when walking that eases with rest, and one foot may be colder than the other. Only an exam and tests such as the ankle-brachial index or a monofilament test can confirm which one you have.

Is one foot colder than the other a sign of poor circulation?

It can be. The NHLBI lists one foot noticeably colder than the other among the signs of peripheral artery disease, along with a pale or bluish color, sores that heal slowly and weak pulses in the legs. Neuropathy more often affects both feet. A foot that suddenly turns cold, pale and painful is different: it can mean acute limb ischemia, an emergency, so call 911.

Is leg pain when walking a sign of neuropathy or poor circulation?

It points more toward poor circulation. Pain, cramping or heaviness in the calf, thigh or buttock that starts while walking and goes away after a few minutes of rest is the classic sign of poor circulation, called intermittent claudication. The NHLBI describes it as the most common PAD symptom. Neuropathy pain is less tied to walking distance and is often worse at night. New walking pain deserves a medical check.

What is a normal ankle-brachial index?

According to the NHLBI, a healthy ankle-brachial index is 1.00 or greater. A resting result below 0.90 suggests peripheral artery disease, and a result below 0.40 is a sign of severe disease. In people with diabetes, stiff or calcified arteries can make the ABI less reliable, so doctors may also use a toe-brachial index, where a result below 0.7 is abnormal.

Can diabetes cause both neuropathy and poor circulation?

Yes. Diabetes is a risk factor for both, and they often occur together. Up to half of people with diabetes develop peripheral neuropathy, according to the NIDDK, and arterial disease in the legs is 2 to 4 times more frequent in people with type 2 diabetes. Neuropathy can also mask the warning pain of poor circulation, which is why yearly foot exams matter.

The bottom line

Nerve symptoms tend to burn or tingle in both feet and flare at night. Circulation symptoms tend to hurt with walking, ease with rest, and show up as a truly cold, pale or slow-healing foot. The two often travel together in diabetes, and no home check separates them. Bring the table to your appointment, ask for an ankle-brachial index and a foot sensation exam, and treat sudden color change, rest pain or a wound that will not heal as reasons to be seen soon.
