Warning Signs of Early-Stage PAD in the Foot

Early-stage PAD warning signs often appear in the feet. You may notice one foot feels colder than the other, changes in skin color, tingling or numbness, slow-healing cuts, shiny skin, slow-growing toenails, or a weaker pulse. These changes can be signs that your feet aren’t getting enough blood.

Peripheral artery disease (PAD) happens when the arteries in your legs narrow, limiting blood flow. Your feet are the farthest from your heart. When blood flow drops, they may show changes first.

Some of these early signs of poor circulation in the feet can be subtle. You might notice them while putting on socks, trimming your toenails, or checking a small cut that is taking longer than usual to heal.

Here’s a look at seven signs of PAD in the feet, why diabetes can make them harder to notice, and when a foot problem should be checked by a doctor.

Why PAD Usually Shows Up in Your Feet First

Your heart pumps blood through arteries that travel all the way down your legs to your feet. PAD narrows those arteries, making it harder for blood to reach the areas below the blockage.

Your feet are at the end of the supply line, farthest from your heart, so they may show signs of reduced blood flow before other PAD symptoms get your attention.

7 Early Warning Signs of PAD in the Foot

What does PAD look like in the feet? Here are seven changes to watch for.

1. One Foot Feels Colder Than the Other

Notice one foot feels colder? Reduced blood flow could be behind it. The difference may be easy to miss at first. Pay closer attention if other changes show up. For example, a change in color or a wound that won’t heal can point to a circulation problem.

2. Color Changes in Your Feet

Take a look at the color of your feet in different positions. With PAD, your foot may appear pale when your leg is raised and red when you lower it.

The change may be subtle in one foot. Looking at both can make it easier to see.

3. Tingling or Numbness in the Foot

Tingling, numbness, or pins and needles can occur with PAD, although circulation problems aren’t the only possible cause. Diabetic neuropathy, or nerve damage caused by diabetes, can cause similar sensations. 

Understanding the connection between leg numbness and poor circulation can help you know when it’s time to talk with your doctor. 

4. Cuts or Blisters That Heal Slowly

Reduced blood flow can slow healing in your feet and toes. A small cut or blister may take longer than usual to heal.

A small wound may go unnoticed when diabetes has caused numbness in your feet. Checking your feet regularly can help you catch it early.

5. Shiny, Thin Skin on the Foot and Ankle

Poor circulation can change the skin on your feet and ankles. It may look thinner or take on a shiny appearance.

These changes can happen slowly. You may notice the difference in your skin before anything else seems unusual.

6. Thickened or Slow-Growing Toenails

Toenails that grow more slowly can accompany reduced circulation in the feet. You may notice that you don’t need to trim them as often.

Nail changes can have several causes. Slow-growing toenails don’t always point to PAD, but they can be worth mentioning if you’ve noticed other changes in your feet. 

7. A Weak Pulse on Top of the Foot

A doctor can feel for a pulse in the arteries in your feet. A weak or difficult-to-detect pulse may indicate reduced blood flow through the leg.

You don’t need to check this yourself. Your doctor can check the pulses in your legs and feet during an exam.

Why Early PAD Is Easy to Miss If You Have Diabetes

Having diabetes increases your risk of developing PAD. Nerve damage from diabetes can also cause numbness in the feet, so you may not feel pain or discomfort that would otherwise get your attention. 

Early PAD can be easy to miss for this reason. PAD and diabetic neuropathy can also share symptoms such as numbness and tingling. 

A daily foot check can help you catch changes you might not feel. Check your feet for any changes, especially around the skin and nails. Some parts of your feet can be hard to see. Have someone you trust take a look when you need help.

When to Worry About Foot Symptoms

Pain at rest is more concerning than pain that only comes with walking. Reduced blood flow can bring about other common symptoms, including pain or cramping in the legs.

If a cut, blister, or sore hasn’t improved within two weeks, have it checked by a doctor. Treating severe circulation problems can help protect the foot and prevent amputation.

If your foot suddenly becomes numb or hard to move, get emergency medical care. A sudden change in skin color is another warning sign.

What Happens Next: Getting Tested for PAD

If your doctor suspects PAD, an ankle-brachial index (ABI) is often the first test used. This quick, painless test compares the blood pressure in your ankle with the blood pressure in your arm. 

Your ABI results can show whether you have reduced blood flow in your legs. From there, your doctor can talk with you about PAD treatment, if needed.

Frequently Asked Questions

What are the first signs of PAD in the feet?

Early signs can include one foot feeling cooler than the other, skin color changes, slow-healing wounds, and slow-growing toenails. Some people have few or no noticeable symptoms.

Can early PAD be reversed?

PAD can’t be cured, but treatment can help keep it from getting worse. Treatment may include medication, structured exercise, managing conditions such as diabetes or high blood pressure, and quitting smoking.

What’s the difference between PAD and neuropathy in the feet?

PAD affects blood flow. Diabetic neuropathy affects the nerves. Numbness can happen with either condition. Your doctor may need to check your nerves and circulation to find out what’s causing it.

Should diabetics check their feet for PAD?

People with diabetes should check their feet every day for cracks, sores, and other changes. Neuropathy can make foot problems less noticeable, so daily checks can help you find changes you may not feel.

Caught Early, PAD Is Highly Treatable

Early-stage PAD warning signs may start with small changes in your feet. Don’t wait for those changes to become more serious. Schedule a consultation with American Endovascular & Amputation Prevention’s affiliated vascular specialists.  They can identify the signs of PAD and offer the proper treatment to make it manageable.
