Foot pain is a common complaint that sends patients to their doctors every day. Whether it’s a burning sensation, numbness, cramping, or a dull ache, pain in the feet and legs can significantly impact your quality of life. However, not all foot pain stems from the same cause. Two of the most common culprits—Peripheral Arterial Disease (PAD) and Neuropathy—often present with similar symptoms but require vastly different treatments.
Distinguishing between these two conditions is critical. Misdiagnosis can lead to ineffective treatment and, in severe cases, dangerous complications like non-healing wounds, gangrene, or even amputation.
At Fox Vein and Vascular in Manhattan, Dr. David Fox and our team specialize in the accurate diagnosis and treatment of vascular conditions. Understanding the difference between PAD and neuropathy is the first step toward finding relief and preserving your limb health.
Understanding the Difference: Circulation vs. Nerves
The primary difference between these two conditions lies in the body systems they affect.
Peripheral Arterial Disease (PAD) is a circulatory problem. It occurs when the arteries supplying blood to your legs become narrowed or blocked by plaque buildup (atherosclerosis). This restricts the flow of oxygen-rich blood to your muscles and skin.
Neuropathy (specifically peripheral neuropathy) is a nerve problem. It involves damage to the peripheral nerves, often caused by diabetes, which disrupts the signals travelling between your brain and your feet.
While you can have both conditions simultaneously—especially if you are diabetic—knowing which one is causing your specific symptoms is essential for effective care.
Identifying Symptoms of PAD
Peripheral Arterial Disease is often called a “silent killer” because early symptoms can be subtle or attributed to aging. However, as the arteries become more blocked, specific warning signs emerge.
1. Claudication (Pain with Activity)
The hallmark symptom of PAD is claudication. This is cramping, heaviness, or fatigue in the leg muscles (calves, thighs, or buttocks) that happens when you walk or climb stairs but goes away when you rest. It occurs because your muscles demand more blood during activity than your narrowed arteries can supply.
2. Changes in Skin and Temperature
Because PAD restricts blood flow, your feet may feel colder than the rest of your body. You might notice the skin on your legs looks shiny, hair growth on the legs slows down or stops, and toenails become brittle or grow slowly.
3. Positional Pain
In severe cases, known as Critical Limb Ischemia (CLI), you may experience pain while lying down, particularly at night. Gravity helps blood flow to the feet; when you elevate your legs in bed, blood flow decreases, causing ischemic rest pain. Hanging your foot over the edge of the bed often brings relief.
4. Arterial Ulcers
Wounds caused by PAD are often located on the toes, heels, or pressure points. These ulcers are typically dry, pale, and incredibly painful. Without restored blood flow, these wounds struggle to heal and can lead to gangrene.
If you suspect your symptoms align with these descriptions, seeking a PAD diagnosis from a vascular specialist is crucial.
Identifying Symptoms of Neuropathy
Neuropathy presents differently because it stems from nerve damage rather than a lack of blood flow.
1. Numbness and Tingling
The most common early sign of neuropathy is a “pins and needles” sensation or numbness in the toes that gradually spreads up the foot and leg. This loss of sensation is dangerous because you might not feel a cut, blister, or injury until it becomes infected.
2. Burning or Sharp Pain
Unlike the cramping of PAD, neuropathic pain is often described as a sharp, electrical, or burning sensation. It can be constant and does not necessarily improve with rest.
3. Sensitivity to Touch
Some patients with neuropathy develop extreme sensitivity (allodynia), where even the weight of a bedsheet on their feet causes severe pain.
4. Neuropathic Foot Ulcers
A neuropathic foot ulcer/wound typically forms on the bottom of the foot where pressure is applied during walking. Unlike arterial ulcers, these are often painless because the nerves are damaged. However, they are prone to deep infection.
Why Accurate Diagnosis Matters
Because symptoms like “foot pain” and “sores” overlap, patients are sometimes treated for nerve issues when they actually have blocked arteries, or vice versa.
If you have PAD but are treated only for neuropathy, your arteries remain blocked. This means your tissues continue to starve for oxygen. If you develop a wound, it won’t heal without blood flow, dramatically increasing the risk of amputation. Conversely, ignoring neuropathy can lead to unnoticed injuries and infections.
Dr. Fox emphasizes that a comprehensive evaluation is the only way to know for sure.
How We Diagnose Your Condition at Fox Vein Care
At our Manhattan vascular surgeon office, we utilize an advanced in-office diagnostic laboratory to differentiate between vascular and neurological causes of pain.
Ankle-Brachial Index (ABI)
This is the gold standard for initial PAD screening. It is a quick, painless test that compares the blood pressure in your ankles to the blood pressure in your arms. A lower pressure in the ankle suggests a blockage in the leg arteries.
Duplex Ultrasound
This non-invasive imaging test allows Dr. Fox to visualize the blood flow through your arteries in real-time. It can pinpoint the exact location and severity of any blockages.
Detailed Physical Exam
A vascular specialist like Dr. Fox will check for pulses in your feet. Weak or absent pulses are a strong indicator of PAD. We also assess skin temperature, color, and capillary refill time.
If your tests confirm PAD, we can create a plan to restore circulation immediately. If your vascular studies are normal, we can rule out PAD and refer you to the appropriate specialist for nerve management.
Minimally Invasive Treatment Options for PAD
If your foot pain is caused by leg circulation problems or blocked leg arteries, medication alone may not be enough. Dr. Fox specializes in minimally invasive, outpatient procedures that restore blood flow without the need for open surgery or hospital stays.
Angioplasty and Stenting
Using a small catheter, Dr. Fox can navigate to the blockage. Angioplasty for PAD involves inflating a tiny balloon to widen the artery. If necessary, stenting for PAD involves placing a small mesh tube to keep the artery open.
Atherectomy
For harder calcified plaque, an atherectomy procedure may be used. This acts like a “roto-rooter,” removing plaque from the vessel walls to clear the path for blood flow.
Limb Salvage
For patients with severe PAD or non-healing wound/ulcer of toe, leg, foot, we employ specialized limb salvage techniques. Restoring flow is often the only way to heal these wounds and prevent amputation.

Risk Factors: Are You at Risk?
Both PAD and neuropathy share common enemies, most notably diabetes. High blood sugar damages both blood vessels and nerves over time.
You should schedule a PAD screening Manhattan evaluation if you have risk factors such as:
- Age over 60
- Diabetes
- Smoking (current or past)
- High blood pressure
- High cholesterol
- Family history of vascular disease
Smoking is the single most significant risk factor for PAD, increasing your risk by 2-6 times.
Don’t Ignore the Pain
Whether your pain is caused by nerve damage or poor circulation, ignoring it is never the right choice. Leg pain, foot pain, and toe pain are your body’s way of signaling that something is wrong.
Early detection is the key to effective treatment. If you are experiencing symptoms of Peripheral Arterial Disease or aren’t sure if your pain is PAD or neuropathy, expert evaluation is necessary.
