Have you ever noticed tingling in your toes, a burning feeling in your feet or difficulty sensing the ground while walking? If you have diabetes, these changes may indicate nerve damage known as diabetic neuropathy.
One of the difficulties with this condition is that it does not always cause pain. Some people gradually lose the ability to feel heat, pressure or minor injuries. They may continue walking with a blister or small cut without realising their skin has been damaged.
Diabetic neuropathy in feet develops when diabetes-related nerve damage interferes with normal sensation. Recognising the symptoms early and checking your feet regularly can help you identify problems before they become more serious.
This article explains why diabetic neuropathy develops, what symptoms to look for, how doctors assess the condition and what you can do to protect your feet.
What Is Diabetic Neuropathy in the Feet?
Diabetic neuropathy is nerve damage associated with diabetes. Peripheral neuropathy commonly affects the feet and legs, although it can also involve the hands and arms.
Your nerves carry messages between your brain, spinal cord and the rest of your body. Sensory nerves allow you to feel touch, pain, temperature and pressure. When these nerves become damaged, the signals may weaken or become distorted.
You might notice:
- Numbness in your toes, soles or other parts of your feet
- Tingling or pins-and-needles sensations
- Burning or shooting pain
- Unusual sensitivity to touch
- Difficulty recognising hot or cold surfaces
- Changes in balance or walking in some cases
Symptoms often develop gradually. Some people experience considerable discomfort, while others have little pain despite a significant loss of sensation.
That difference matters because pain normally alerts you to an injury. When protective sensation is reduced, you may not realise that your foot needs attention.
Why Does Diabetes Cause Loss of Foot Sensation?
Diabetes can damage nerves over time, particularly when blood glucose levels remain above an individual’s target range. The condition may affect the nerves directly and damage the small blood vessels that supply them.
Several factors can contribute to diabetic neuropathy.
- High Blood Glucose Levels Over Time
Persistently elevated blood glucose can interfere with normal nerve function and damage nerve cells. As this damage progresses, sensory messages may not travel properly between your feet and brain.
You might stop noticing pressure from tight footwear or fail to recognise a minor cut. Keeping blood glucose within your recommended range is an important part of diabetes management, although it cannot guarantee that nerve damage will be prevented or reversed.
- Damage to Small Blood Vessels
Nerves need oxygen and nutrients supplied by blood vessels. Diabetes can damage these small vessels, affecting the blood supply that supports healthy nerve function.
Over time, this can contribute to reduced sensation in the feet.
- How Long You Have Had Diabetes
The risk of nerve damage generally increases with the duration of diabetes. Blood glucose that is difficult to manage, high blood pressure, abnormal cholesterol levels, excess body weight and smoking can also contribute to complications.
However, neuropathy does not affect everyone in the same way. A person may develop symptoms even if they have not experienced obvious problems with their diabetes before.
- Other Causes of Foot Numbness
Not all foot numbness in someone with diabetes is caused by diabetic neuropathy.
Vitamin B12 deficiency, thyroid disorders, certain medicines, nerve compression and other neurological conditions can produce similar symptoms.
A clinical assessment can help identify the likely cause and determine whether further tests are necessary.

What Are the Early Signs of Diabetic Neuropathy?
The first symptoms can be easy to overlook. You may notice an unusual sensation before you experience significant numbness.
Common warning signs include:
- Tingling in the toes or soles
- Burning feet, particularly at night
- Sharp or electric-like pain
- Reduced sensitivity to touch
- Difficulty feeling hot or cold water
- A sensation similar to walking on padding
- Less awareness of stones or objects inside your shoes
- Changes in balance or walking
Symptoms often affect both feet, although the pattern can vary.
Pay attention to changes that persist, recur or gradually become more noticeable. Do not assume that your feet are healthy simply because they do not hurt. Reduced sensation can hide an injury that would otherwise be painful.
How Is Diabetic Neuropathy Diagnosed?
Diagnosis usually begins with a discussion about your symptoms, medical history, diabetes management and any previous foot problems.
A healthcare professional may examine your feet, check sensation and assess circulation. The tests recommended will depend on your symptoms and examination findings.
Who Is at Risk of Diabetic Neuropathy?
Anyone with diabetes can develop nerve damage. The likelihood increases with certain health and lifestyle factors.
These include:
- Having diabetes for many years
- Blood glucose levels frequently remaining above the recommended range
- High blood pressure
- Abnormal cholesterol levels
- Excess body weight
- Smoking
- A history of diabetic foot ulcers or injuries
- Other conditions affecting nerves or circulation
Having these risk factors does not mean you will necessarily develop neuropathy. Equally, the absence of obvious risk factors does not rule it out.
If you have diabetes, include foot examinations in your regular healthcare routine, even when your feet feel normal.
Why Is Foot Numbness a Concern for People With Diabetes?
The main concern is the loss of protective sensation.
Imagine wearing a shoe that rubs against your heel. Most people would feel discomfort and adjust the shoe or stop walking. Someone with diabetic neuropathy might not notice the friction until a blister has formed.
If the injury goes unnoticed, it can develop into a wound or foot ulcer. Infection and delayed healing can make the problem more difficult to manage.
Diabetes-related circulation problems may also occur alongside nerve damage, further increasing the risk of complications.
Possible problems include:
- Blisters, cuts and unnoticed injuries
- Diabetic foot ulcers
- Skin and soft-tissue infections
- Wounds that heal slowly
- Changes in foot shape, including Charcot foot in some cases
- Severe tissue damage when complications are not treated promptly
These complications are not inevitable. Regular foot checks, appropriate diabetes management and early assessment of injuries can help reduce the risk.
Foot Examination and Sensation Testing
An assessment may include:
- Checking the skin, nails, toes and soles for cuts, calluses, swelling or colour changes
- Examining foot temperature and circulation
- Testing protective sensation with a monofilament or other appropriate methods
- Checking vibration sensation, reflexes or balance when indicated
- Reviewing footwear for areas of pressure or friction
These checks help identify reduced protective sensation and possible foot complications.
Are Nerve Conduction Studies Necessary?
A nerve conduction study measures how electrical signals travel along selected peripheral nerves. It may be recommended when additional information about nerve function is needed.
Not everyone with suspected diabetic neuropathy requires this test. Your healthcare professional will decide whether it is appropriate based on your symptoms and clinical findings.
Blood tests may also be considered when another cause of numbness is suspected. These can include tests for vitamin B12 deficiency, thyroid problems or other possible contributors.
Can Diabetic Neuropathy Be Treated?
Treatment depends on the cause, the symptoms and the extent of nerve damage. Care generally focuses on managing diabetes, addressing contributing health conditions, relieving nerve pain where possible and preventing foot injuries.
Managing Blood Glucose and Other Health Risks
Work with your treating healthcare professional to keep blood glucose within your individual target range. Managing blood pressure and cholesterol, taking prescribed medicines as directed and avoiding smoking can also help reduce the risk of further complications.
Better diabetes management may help slow the progression of nerve damage, but it does not guarantee that established nerve damage will reverse.
Treating Nerve Pain
If neuropathy causes burning, shooting pain or discomfort, a clinician may recommend medicines or other treatments suited to your symptoms and medical history.
Pain management does not restore lost protective sensation. Even if the discomfort improves, regular foot inspections remain important.
Do not start supplements, stop prescribed medicines or rely on unverified home remedies without discussing them with a healthcare professional.
Getting Foot Injuries Assessed
A wound or ulcer may require professional assessment, appropriate dressings, pressure reduction, infection management or other treatment depending on its severity.
If you have reduced sensation, do not wait for a foot injury to become painful before seeking advice. An apparently small wound may need attention even when you feel no discomfort.
How Can You Protect Your Feet Every Day?
Daily foot care is particularly important if you have diabetes and reduced sensation. A simple routine can help you notice changes before they become more serious.
1. Check Both Feet Every Day
Look at the soles, heels, toes, spaces between your toes and the skin around your nails. Use a mirror or ask someone to help if you cannot see the bottom of your feet clearly.
2. Wash and Dry Carefully
Use warm, not hot, water. Dry your feet thoroughly, especially between the toes. Avoid soaking your feet for long periods unless your healthcare professional advises otherwise.
3. Wear Properly Fitting Shoes
Choose footwear that fits comfortably and does not rub against your skin. Check inside your shoes for small stones, rough surfaces or other objects before putting them on.
4. Avoid Walking Barefoot
Wear appropriate footwear indoors and outdoors. This reduces the chance of cuts, punctures and burns that you might not feel.
5. Protect Your Feet From Heat
Avoid placing your feet directly against heaters or using hot-water bottles and heating pads on them. Reduced sensation can make it difficult to recognise a burn.
6. Do Not Remove Corns or Calluses Yourself
Avoid blades, sharp tools and strong chemical corn removers. If you have diabetes and reduced sensation, ask a healthcare professional about safe treatment options.
7. Watch for Changes in the Skin
Look for redness, swelling, blisters, cracks, discharge, unusual warmth or changes in skin colour. Seek medical advice promptly if you notice a new injury.
8. Attend Regular Foot Examinations
Ask your healthcare professional how often your feet should be checked. The recommended frequency depends on your sensation, circulation, medical history and risk of complications.
If you discover a wound or blister, do not judge its seriousness by whether it hurts. Reduced sensation can make an injury less noticeable without making it harmless.
Conclusion
Diabetic neuropathy in feet occurs when diabetes-related nerve damage affects normal sensation. It can cause tingling, burning pain or numbness, but some people lose protective sensation without experiencing much discomfort.
If you have diabetes, check your feet daily, wear suitable footwear and follow your diabetes management plan. Seek medical advice for persistent numbness or any new foot injury, even if it does not hurt.
Recognising changes early gives you and your healthcare team an opportunity to assess the problem and take steps to protect your foot health.

Frequently Asked Questions (FAQs)
People with diabetes may lose sensation because prolonged high blood glucose can damage peripheral nerves and the small blood vessels that supply them. This condition, known as diabetic peripheral neuropathy, can reduce the ability to feel touch, pressure, pain, heat and cold.
Early symptoms can include tingling, burning, pins-and-needles sensations, shooting pain or reduced sensitivity in the toes and soles. Some people also experience changes in balance, while others develop numbness without significant pain.
Recovery depends on the cause and extent of nerve damage. Managing blood glucose and treating contributing conditions may help prevent further damage, but established nerve damage may not be fully reversible. A healthcare professional can assess the likely cause and discuss suitable management.
Yes. Reduced sensation can make it difficult to notice cuts, blisters, burns and foot ulcers. These injuries may worsen or become infected before they are detected. Daily foot inspections are important even when your feet do not hurt.
Diagnosis generally involves reviewing symptoms and medical history, examining the feet and testing sensation. Depending on the findings, a clinician may assess circulation, vibration sensation and reflexes or recommend nerve conduction studies and blood tests to investigate other possible causes.
Inspect your feet daily, wash them with warm rather than hot water, dry them carefully, wear well-fitting footwear and avoid walking barefoot. Do not use sharp tools or strong chemical products to remove corns or calluses. Seek medical advice promptly if you notice a wound, swelling or a change in skin colour.
Arrange an assessment for new or worsening numbness, tingling, burning pain or reduced temperature sensation. A wound, ulcer, spreading redness, swelling, discharge or blackened skin needs urgent medical attention. Sudden numbness with weakness or other stroke-like symptoms requires emergency care.
