View Doctor Profile →Diabetic foot problems can range from dry or cracked skin and calluses to nerve damage, infections, foot ulcers, and changes in foot shape. Diabetes can make these problems more serious because nerve damage may reduce the ability to feel an injury, while reduced blood flow can make wounds harder to heal.
The good news is that daily foot checks, regular medical examinations, appropriate footwear, and good diabetes management can help identify problems early and reduce the risk of serious complications.
Quick answer: Common diabetic foot problems include numbness or tingling, dry or cracked skin, calluses, blisters, infections, foot ulcers, and deformities. Nerve damage can make injuries difficult to notice, while peripheral artery disease can interfere with healing. People with diabetes should inspect their feet every day and have a comprehensive foot examination at least once a year, with more frequent assessment when risk is higher.

What Are Diabetic Foot Problems?
Diabetic foot problems are conditions affecting the feet that are more likely to occur or become complicated in people with diabetes.
Diabetes can affect the feet in several ways. Peripheral neuropathy can reduce sensation, making it difficult to notice a blister, cut, burn, pressure point, or other injury. Diabetes can also affect blood vessels and circulation, making it harder for some wounds to heal.
A small problem that would normally be noticed and treated quickly can therefore become an ulcer or infection if it goes unnoticed.
Diabetic foot complications may include:
- Numbness or loss of protective sensation
- Tingling or burning
- Dry, cracked skin
- Calluses and corns
- Blisters
- Ingrown toenails
- Fungal infections
- Cuts and sores
- Foot ulcers
- Changes in foot shape
- Charcot foot
- Poor circulation
- Serious infections
Not everyone with diabetes develops these problems, but regular foot care is important because some complications can develop without significant pain.
Diabetic Retinopathy: 7 Essential Signs, Stages, Treatment & Prevention
7 Warning Signs of Diabetic Foot Problems
Knowing what to look for can help you act before a minor problem becomes more serious.
1. Numbness, Tingling or Burning
Numbness, tingling, burning, or unusual sensations in the feet can be signs of diabetic peripheral neuropathy.
Some people experience pain, while others gradually lose their ability to feel pressure, temperature, or minor injuries. Loss of protective sensation is particularly important because a person may continue walking on an injured area without realizing it.
2. Cuts, Blisters or Sores
A blister from an uncomfortable shoe or a small cut can become a problem if it is not noticed or treated.
Check the bottoms of your feet and between your toes every day. If you cannot see the bottoms of your feet easily, use a mirror or ask someone you trust to help.
3. Redness, Swelling or Increased Warmth
A new area of redness, swelling, or unusual warmth can indicate irritation, inflammation, infection, or another foot problem.
The 2026 ADA Standards specifically recommend urgent specialist assessment for people with diabetes who have an open ulcer or unexplained swelling, redness, or increased skin temperature.
4. Changes in Skin Color or Temperature
A foot that becomes unusually pale, bluish, red, or different in temperature from the other foot deserves attention.
Changes in color or temperature can sometimes be associated with circulation problems or infection. CDC guidance lists changes in foot color and temperature among reasons to contact a healthcare professional.
5. Dry, Cracked Skin or Thick Calluses
Dry skin and calluses may seem minor, but repeated pressure or friction can damage the skin.
Calluses can become particularly concerning when combined with loss of sensation because pressure may continue without the person noticing it. The ADA recommends avoiding self-treatment of calluses and ingrown nails in people with higher-risk feet.
6. Changes in the Shape of the Foot
Diabetes-related nerve damage can sometimes contribute to structural changes.
One example is Charcot foot, a relatively uncommon but serious complication in which bones and tissues of the foot can become damaged. Early signs may include warmth, redness, and swelling; later, the shape of the foot may change.
7. A Foot Ulcer or Infection
A diabetic foot ulcer is an open wound occurring below the ankle in a person with diabetes.
Ulcers can become infected and, when severe or untreated, may lead to hospitalization or amputation. The risk is higher when neuropathy, poor circulation, deformity, or a previous ulcer is present.
Diabetic Neuropathy Explained: Symptoms, Types, Causes, Treatment & Prevention
Why Does Diabetes Cause Foot Problems?
Diabetic foot problems usually develop through a combination of factors rather than one single cause.
Nerve damage
High blood glucose over time can contribute to diabetic neuropathy. When protective sensation is reduced, pressure, friction, heat, or injuries may go unnoticed.
Reduced blood flow
Peripheral artery disease and other circulation problems can reduce blood supply to the legs and feet. Poor circulation can make wounds more difficult to heal.
Repeated pressure or friction
Shoes that do not fit properly can create pressure points, blisters, calluses, and skin injuries.
Foot deformities
Bunions, hammertoes, Charcot foot, and other structural changes can increase pressure on particular areas of the foot.
Previous ulcers or amputation
A history of a diabetic foot ulcer or amputation places a person at higher risk of future complications and usually requires closer surveillance.
Smoking
Smoking can reduce blood flow and is an important risk factor considered when assessing diabetic foot health.
Everyday Habits That Increase Diabetes Risk: 10 Everyday Behaviors to Watch
What Is a Diabetic Foot Ulcer?
A diabetic foot ulcer is an open break in the skin of the foot in a person with diabetes.
It often develops after repeated pressure, friction, or minor trauma, particularly when protective sensation has been reduced by neuropathy. Poor circulation can further interfere with healing.
A foot ulcer may appear as:
- An open sore
- A shallow or deep wound
- A red or irritated area
- A wound surrounded by thick callused skin
- Drainage from the affected area
A foot ulcer should not be treated as an ordinary cut. Contact a healthcare professional promptly for assessment.
What Is Diabetic Neuropathy and Why Does It Matter?
Diabetic neuropathy is nerve damage associated with diabetes.
Peripheral neuropathy commonly affects the feet and may cause:
- Burning
- Tingling
- Numbness
- Sharp or shooting pain
- Reduced ability to feel temperature
- Loss of protective sensation
- Balance problems
The 2026 ADA Standards state that diabetic peripheral neuropathy can be asymptomatic in many people, which is one reason routine screening matters.
When sensation is reduced, a person may step on a sharp object, develop a blister, or suffer a minor burn without realizing it.
What Is Peripheral Artery Disease?
Peripheral artery disease (PAD) occurs when blood flow through arteries supplying the legs is reduced.
In people with diabetes, PAD can contribute to foot problems and delayed wound healing.
Possible symptoms include:
- Leg fatigue during activity
- Cramping in the calves, thighs, or buttocks during walking
- Foot or leg pain
- Changes in skin color
- Cold feet
- Reduced pulses
Some people may have few obvious symptoms, so vascular assessment is part of comprehensive diabetic foot evaluation. The 2026 ADA Standards recommend assessing pulses and other vascular findings and pursuing further evaluation when PAD is suspected.
How to Prevent Type 2 Diabetes: Evidence-Based Ways to Lower Your Risk
How Are Diabetic Foot Problems Diagnosed?
A healthcare professional may examine several aspects of foot health.
1. Skin examination
The clinician looks for:
- Cuts
- Ulcers
- Blisters
- Calluses
- Cracks
- Redness
- Swelling
- Infection
- Changes in skin temperature
2. Neurological examination
The clinician may assess sensation using tools such as a 10-g monofilament, along with another test of neurological function such as vibration, temperature, or pinprick sensation.
3. Circulation assessment
The clinician may check pulses in the feet and legs and look for signs suggesting reduced blood flow.
4. Foot structure
The shape of the feet and toes is assessed for:
- Bunions
- Hammertoes
- Prominent bones
- Charcot changes
- Other deformities
5. Medical history
Your healthcare team may ask about:
- Previous ulcers
- Previous amputation
- Neuropathy
- Smoking
- Kidney disease
- Retinopathy
- Circulation symptoms
- Current medications
- Previous vascular procedures
How Often Should People With Diabetes Have a Foot Exam?
The 2026 ADA Standards of Care recommend a comprehensive foot evaluation at least once a year for people with diabetes.
The examination should include:
- Skin inspection
- Assessment for deformities
- Neurological assessment
- Testing for loss of protective sensation
- Vascular assessment, including pulses
People with loss of protective sensation, previous ulceration, or previous amputation may need their feet checked at every visit.
Risk-based follow-up can be more frequent. The 2026 ADA Standards describe intervals ranging from every 6–12 months for some lower-risk patients to every 1–3 months for people in the highest-risk category.
How to Check Your Feet Every Day
A daily foot check is one of the simplest habits you can build into diabetes care.
Look for:
- Cuts
- Blisters
- Sores
- Red spots
- Swelling
- Warm areas
- Cracked skin
- Calluses
- Corns
- Ingrown toenails
- Skin-color changes
- Drainage
Remember to check:
Top of the foot → sole → heel → between the toes.
If you cannot see the bottom of your feet, use a mirror or ask another person to help.
Diabetic Foot Care: 10 Practical Daily Tips
1. Check your feet every day
Do not rely on pain as your warning signal. Nerve damage can reduce sensation.
2. Wash your feet carefully
Use warm—not very hot—water and gently wash your feet. Dry them thoroughly afterward, especially between the toes.
3. Moisturize dry skin
A moisturizer can help keep dry skin from cracking.
Avoid putting moisturizer between the toes because excessive moisture in that area can encourage infection.
4. Never walk barefoot
Wear appropriate footwear even indoors if your healthcare team has advised this, particularly when you have reduced sensation. Walking barefoot increases the chance of an unnoticed injury.
5. Choose properly fitting shoes
Shoes should provide enough room and should not create pressure points.
People at high risk of ulcers may benefit from specialized therapeutic footwear recommended by a foot-care professional.
6. Trim toenails carefully
Trim toenails straight across rather than cutting deeply into the corners. If you cannot safely see, reach, or feel your feet, ask a healthcare professional about nail care.
7. Don’t cut your own calluses
Avoid cutting corns or calluses yourself and avoid medicated corn-removal products unless specifically advised by a healthcare professional.
8. Protect your feet from heat
Neuropathy can reduce your ability to detect excessive heat.
Avoid heating pads, hot-water bottles, and direct contact with heaters on your feet.
9. Keep your diabetes under control
Managing blood glucose, blood pressure, and cholesterol can help reduce the progression of nerve damage and other diabetes-related complications.
10. Keep your medical appointments
Regular foot examinations allow problems to be identified before they become more serious.
Can You Exercise With Diabetic Foot Problems?
Physical activity can be beneficial for people with diabetes, but the right activity depends on the condition of your feet.
If you have an open ulcer, significant swelling, infection, severe pain, or another active foot problem, ask your healthcare professional which activities are safe.
For people without active foot wounds, lower-impact activities may sometimes be easier on the feet. NIDDK lists options such as swimming, cycling, yoga, stretching, and other activities that may reduce foot stress.
Do not use exercise to “walk off” a foot wound or persistent foot pain.
How Are Diabetic Foot Problems Treated?
Treatment depends on the specific problem.
Neuropathy
Treatment focuses on diabetes management, reducing further nerve damage, protecting the feet, and treating troublesome symptoms when necessary.
Calluses or pressure areas
The cause of repeated pressure should be addressed. A foot-care professional may recommend appropriate footwear or pressure-relieving measures.
Foot ulcers
Ulcers require professional assessment. Treatment may involve wound care, pressure relief, infection management when present, and addressing circulation problems or other underlying causes.
Infection
A suspected diabetic foot infection needs prompt medical assessment. Treatment depends on the severity and type of infection.
Peripheral artery disease
When circulation problems are suspected, additional vascular evaluation may be needed. Treatment is individualized according to the severity and overall cardiovascular risk.
High-risk feet
The ADA recommends an interprofessional approach for people with ulcers and high-risk feet, including individuals with conditions such as loss of protective sensation, PAD, Charcot foot, previous ulcers, or previous amputation.
What Is Charcot Foot?
Charcot foot is an uncommon but serious complication associated with diabetes-related nerve damage.
Early findings may include:
- Warmth
- Redness
- Swelling
As the condition progresses, bones and joints can become damaged and the shape of the foot may change.
Because Charcot foot can sometimes occur with reduced sensation, a person may not experience pain that matches the seriousness of the condition.
Unexplained warmth, redness, or swelling in a diabetic foot should be evaluated promptly.
When Should You See a Doctor for Diabetic Foot Problems?
Contact your healthcare professional promptly if you notice:
- A new cut or sore
- A blister that is not improving
- An open ulcer
- Redness
- Swelling
- Increased warmth
- Drainage or pus
- A bad smell from a wound
- New numbness
- Burning or persistent foot pain
- A change in foot shape
- Skin-color changes
- A sudden difference between one foot and the other
CDC guidance specifically recommends contacting a doctor or foot specialist for symptoms such as tingling, burning, loss of sensation, changes in foot color or temperature, dry cracked skin, thickened toenails, fungal infections, ingrown toenails, blisters, ulcers, or infected corns.
When Is a Diabetic Foot Problem an Urgent Concern?
Don’t wait for a routine appointment if you have:
An open wound + redness/swelling/warmth + drainage, fever, worsening pain, or rapidly changing skin.
A diabetic foot infection can progress quickly, and infection may sometimes appear less dramatic than expected when neuropathy or poor circulation is present.
Urgent assessment is especially important for people with a history of ulcers, amputation, PAD, loss of protective sensation, or Charcot foot.
Can Diabetic Foot Problems Be Prevented?
Not every diabetic foot problem can be prevented, but many risks can be reduced.
The most useful habits are:
- Check your feet every day.
- Have a comprehensive foot exam at least annually.
- Wear appropriate shoes and socks.
- Avoid walking barefoot.
- Protect feet from extreme temperatures.
- Treat cuts and blisters promptly with professional guidance.
- Don’t cut calluses yourself.
- Manage blood glucose, blood pressure, and cholesterol.
- Don’t smoke.
- Seek medical attention early for new foot changes.
These measures are consistent with current ADA and NIDDK foot-care recommendations.

Frequently Asked Questions About Diabetic Foot Problems
What are the most common diabetic foot problems?
Common problems include numbness, tingling, burning, dry or cracked skin, calluses, blisters, fungal infections, ingrown toenails, ulcers, infections, poor circulation, and foot deformities.
What does diabetic foot pain feel like?
Diabetic foot pain related to neuropathy can feel like burning, tingling, stabbing, shooting, or unusual sensitivity. However, some people with significant nerve damage have little or no pain because sensation is reduced.
Can diabetes cause numb feet?
Yes. Diabetes-related peripheral neuropathy can cause reduced sensation or numbness in the feet. Loss of protective sensation can increase the risk of unnoticed injuries.
Can diabetic foot problems heal?
Many foot problems can improve with early and appropriate treatment. However, healing depends on the type and severity of the problem, blood flow, infection, pressure on the area, nerve function, and overall diabetes management.
How often should I check my feet if I have diabetes?
Check your feet every day. Daily inspection is recommended because problems may develop without pain or obvious symptoms.
Should people with diabetes walk barefoot?
Generally, avoiding barefoot walking is recommended, particularly when sensation is reduced, because an injury may go unnoticed.
Should I cut a diabetic foot callus?
Do not cut a callus yourself. Diabetes-related nerve or circulation problems can make self-treatment risky. Ask a healthcare professional or foot-care specialist about appropriate treatment.
Can diabetic foot problems lead to amputation?
Severe ulcers, infections, poor circulation, and other complications can sometimes lead to amputation. However, early recognition, preventive foot care, and appropriate treatment can reduce the risk of serious complications.
What is the best way to prevent diabetic foot ulcers?
There is no single prevention method. Daily foot inspection, appropriate footwear, regular professional foot examinations, management of diabetes and cardiovascular risk factors, and early treatment of injuries are key parts of prevention.
Can diabetic foot problems occur without pain?
Yes. This is particularly important when peripheral neuropathy causes loss of protective sensation. A person can have a blister, cut, ulcer, or other injury without feeling it.
What should I do if I find a small cut on my foot?
Don’t ignore it. Keep the area clean and protected and contact your healthcare professional for guidance, particularly if you have neuropathy, poor circulation, a previous ulcer, or other high-risk features. Watch closely for redness, swelling, warmth, drainage, or worsening symptoms.
What type of doctor treats diabetic foot problems?
Depending on the problem, care may involve a primary-care clinician, podiatrist, endocrinologist, wound-care specialist, vascular specialist, or other members of an interdisciplinary team. High-risk feet and ulcers may require coordinated specialist care.
