Diabetic Neuropathy: 10 Warning Signs of Diabetes Nerve Damage & How to Protect Your Feet

Diabetes can affect much more than blood sugar. Over time, elevated blood glucose can damage nerves and the small blood vessels that support them. This condition is called diabetic neuropathy.

One of the most common forms is peripheral neuropathy, which frequently affects the feet and legs. Symptoms can include numbness, burning, tingling, pain, weakness and difficulty sensing temperature or injuries. �

The problem isn't simply uncomfortable feet. Reduced sensation can make it difficult to notice a blister, cut or other injury, allowing a small problem to become infected or develop into an ulcer.

That's why understanding the early warning signs and practicing daily foot care are so important.

What Is Diabetic Neuropathy?

Diabetic neuropathy is nerve damage associated with diabetes.

Peripheral neuropathy commonly affects the feet and legs, although it can also affect the hands and arms. Other forms of diabetic neuropathy can affect nerves controlling organs and body functions. �

NIDDK +1

Nerve damage generally develops over time. Some people may have mild nerve damage without obvious symptoms, while others experience significant pain or sensory changes.

10 Warning Signs of Diabetic Nerve Damage

1. Numbness in Your Feet

Do your feet sometimes feel numb, "asleep," or less sensitive than they used to?

Reduced sensation can be an early sign of peripheral neuropathy.

The important concern is that numbness can reduce your ability to recognize injuries.

2. Burning Sensation

A burning feeling in the feet—especially when resting or at night—can occur with diabetic peripheral neuropathy.

It may feel like your feet are unusually hot even when they aren't.

3. Tingling or "Pins and Needles"

Some people experience persistent tingling, prickling or a pins-and-needles sensation.

These symptoms may occur in the feet, legs, hands or arms. �

4. Shooting or Electric-Like Pain

Neuropathic pain can sometimes feel sharp, stabbing, shooting or electric.

For some people, symptoms become particularly noticeable at night. �

5. Reduced Ability to Feel Temperature

Nerve damage can affect your ability to sense heat and cold.

This means you may not recognize that water or another object is dangerously hot.

6. You Don't Notice Foot Injuries

This is one of the biggest concerns with diabetic neuropathy.

A person with reduced sensation may develop a blister, cut or sore without feeling significant pain.

CDC recommends checking your feet every day—even when they feel completely normal. �

7. Balance Problems

Peripheral neuropathy can affect sensation, coordination and walking.

Reduced sensation in the feet may contribute to balance problems and increase the risk of falls. �

8. Dry, Cracked or Changing Skin

Changes such as dry or cracked skin, redness, swelling or changes in the appearance of your feet deserve attention.

Don't assume a painless change is harmless.

9. Blisters, Sores or Ulcers

A blister or small wound can become more serious when sensation is reduced.

Diabetes can also make wounds harder to heal, particularly when circulation is poor. �

NIDDK

10. Changes in the Shape of Your Feet

Diabetic nerve damage can sometimes be associated with changes in the structure of the foot.

A noticeable change in foot shape, particularly when accompanied by redness, warmth or swelling, should be evaluated by a healthcare professional. �

Why High Blood Sugar Can Damage Nerves

Persistent high blood glucose is an important risk factor for diabetic nerve damage.

Other factors can contribute to risk, including having diabetes for many years, overweight or obesity, high blood pressure and high cholesterol. �

This is why diabetes management isn't only about checking a glucose number.

It also involves protecting your nerves, circulation, eyes, kidneys, heart and feet.

7 Simple Ways to Protect Your Feet

1. Check Your Feet Every Day

Make a daily habit of looking for:

Cuts

Blisters

Redness

Swelling

Cracks

Sores

Changes in skin color

Corns or calluses

Ingrown toenails

Signs of infection

If you can't see the bottoms of your feet easily, use a mirror or ask someone to help. �

2. Avoid Walking Barefoot

Even inside your home, footwear can provide protection against objects that could injure your feet.

Choose comfortable shoes that fit properly. �

3. Keep Blood Sugar in Your Target Range

Good diabetes management can help prevent or delay nerve damage and may slow its progression.

Work with your healthcare team to determine your personal glucose targets. �

4. Take Care of Your Skin

Wash your feet with warm—not extremely hot—water and dry them carefully.

If your skin is dry, moisturizer can help, but CDC advises avoiding lotion between the toes because excess moisture there can contribute to infection. �

5. Don't Treat Corns or Calluses Aggressively Yourself

People with reduced foot sensation can accidentally injure their skin while trying to remove a corn or callus.

Ask your healthcare professional about the safest approach. �

CDC

6. Don't Smoke

Smoking reduces blood flow and can increase problems involving the feet.

If you smoke, talk with your healthcare professional about evidence-based ways to quit. �

CDC

7. Keep Your Regular Medical Appointments

People with diabetes should have their feet examined regularly. NIDDK recommends at least an annual foot examination, with more frequent assessment when foot problems or neuropathy are present. �

Can Diabetic Neuropathy Be Reversed?

This is an important question.

Once diabetic nerve damage has developed, treatment generally focuses on preventing further damage, controlling the underlying risk factors and managing symptoms such as nerve pain. NIDDK notes that established nerve damage cannot simply be reversed with a single treatment. �

NIDDK

Treatment depends on the individual and may include better diabetes management, lifestyle measures and medications for neuropathic pain when appropriate.

Don't start supplements or prescription medicines for neuropathy without discussing them with a healthcare professional.

When Should You Contact a Doctor?

Don't wait for a routine appointment if you have:

A foot wound that isn't healing

Increasing redness or swelling

Signs of infection

A foot ulcer

New or worsening numbness

Burning or tingling that interferes with sleep or daily activities

Significant changes in foot color or temperature

A sudden change in foot shape

Severe or unexplained foot pain

CDC specifically recommends prompt medical attention for foot sores, ulcers, infections and concerning sensory changes. �

The 60-Second Daily Foot Check

A simple routine can make foot care easier:

LOOK → FEEL → PROTECT → REPORT

LOOK: Check both feet for cuts, blisters, redness and swelling.

FEEL: Notice whether sensation has changed.

PROTECT: Wear properly fitting shoes and avoid walking barefoot.

REPORT: Tell your healthcare professional about new or worsening problems.

Daily observation is especially important when neuropathy has reduced your ability to feel pain. �

CDC

Final Takeaway

Diabetic neuropathy can begin quietly.

Numbness, tingling, burning, shooting pain and reduced sensation shouldn't simply be ignored—particularly in someone with diabetes.

The good news is that consistent diabetes management and daily foot care can help reduce the risk of serious complications. Checking your feet every day, protecting them from injury and seeking medical attention early when something changes are simple but important habits. �

CDC +1

Your feet may not always tell you something is wrong. Your daily foot check can.
