If you have diabetes, your feet need special attention. Diabetes can cause two serious complications that affect your feet:

• Diabetic neuropathy — Nerve damage that causes numbness, tingling, or complete loss of sensation. You might not feel injuries, blisters, or sores.
• Poor circulation — Reduced blood flow makes it harder for wounds to heal and increases infection risk.

Together, these complications create a dangerous situation: you might not feel an injury when it happens, and when you do notice it, healing is slower and infection risk is higher.

The good news: Most diabetic foot complications are preventable with proper care and early detection.

Problem #1: Any Cut, Sore, or Ulcer That Won't Heal

A small cut on your foot might seem minor, but for diabetics, it can quickly become serious.

What counts as "won't heal"? If a wound hasn't shown significant improvement within 3-5 days of proper home care, it needs professional evaluation. Don't wait weeks hoping it will get better.

Why This Happens

High blood sugar impairs your immune system and reduces blood flow. This means:

• White blood cells can't reach the wound effectively
• Bacteria multiply faster in high-glucose environments
• New tissue formation is slower
• Infections spread more quickly

What to Do

• Clean the wound immediately with mild soap and water
• Apply antibiotic ointment
• Cover with a sterile bandage
• Change dressing daily
• Call us if no improvement within 3-5 days

Problem #2: Changes in Foot Color or Temperature

Your feet should be pink and warm (not hot). Color and temperature changes signal underlying problems.

Red and Warm

Indicates inflammation or infection. Could be cellulitis (skin infection), an abscess, or Charcot foot (a serious diabetic complication where bones weaken and fracture).

Action: Call us same-day. Infections can spread rapidly in diabetics.

Pale or Blue

Suggests poor circulation. Your tissues aren't getting enough oxygenated blood.

Action: Schedule an appointment within 48 hours. We'll assess circulation and may refer you for vascular evaluation.

Black Areas

This is tissue death (gangrene). This is a medical emergency.

Action: Go to the ER immediately. Do not wait for an office appointment.

One Foot Colder Than the Other

Asymmetry is always concerning. Could indicate a blockage in blood flow to one leg.

Action: Call us within 24-48 hours for evaluation.

Problem #3: Swelling in One or Both Feet

Some swelling after a long day is normal. But persistent or asymmetric swelling needs evaluation.

When Swelling Is Concerning

• Swelling in only one foot (asymmetry)
• Swelling that doesn't improve with elevation
• Swelling accompanied by redness or warmth
• Sudden onset of significant swelling
• Swelling with skin breakdown or weeping

Possible Causes

• Infection (cellulitis)
• Deep vein thrombosis (blood clot)
• Charcot foot
• Heart or kidney issues (usually both feet)
• Lymphedema

Problem #4: Numbness, Tingling, or Burning

These are classic signs of diabetic neuropathy. Ironically, the absence of pain can be more dangerous than pain itself.

Why "No Pain" Isn't Good News

When you lose sensation, you can't feel:

• Rocks or debris in your shoes
• Blisters forming
• Cuts or puncture wounds
• Burns from hot water or surfaces
• Pressure from ill-fitting shoes

This means injuries can develop and worsen without you knowing until there's visible damage or infection.

Protection Strategies

• Inspect your feet daily — Use a mirror or ask for help if needed
• Never walk barefoot — Even indoors
• Check shoes before putting them on — Feel inside for debris
• Test water temperature — Use your elbow, not your foot
• Wear proper diabetic shoes — Medicare may cover these

Problem #5: Ingrown Toenails or Fungal Infections

What's a minor nuisance for non-diabetics can become serious for those with diabetes.

Ingrown Toenails

The broken skin around an ingrown nail is an entry point for bacteria. In diabetics, this can quickly progress to deep infection or bone infection (osteomyelitis).

Never DIY: Don't try to dig out the nail yourself. See a podiatrist for safe removal.

Fungal Infections

Athlete's foot and fungal nail infections cause skin breakdown and cracking, creating entry points for bacteria. Fungal nails also become thick and can cause pressure sores.

Treatment options: Prescription antifungals, laser treatment, or nail removal in severe cases.

Prevention Is Your Best Defense

The strategies above help you catch problems early. But prevention is even better:

Blood Sugar Control

Keeping your blood sugar in target range is the single most important thing you can do. Good control slows or prevents neuropathy and circulation problems.

Proper Footwear

• Wear shoes at all times (no barefoot walking)
• Choose shoes with wide toe boxes
• Break in new shoes gradually
• Consider diabetic shoes if you qualify (Medicare covers these)

Regular Podiatrist Visits

• Annual comprehensive diabetic foot exam — Covered by Medicare
• Every 2-3 months if you have neuropathy, poor circulation, or previous ulcers
• Immediately for any concerning changes

Nail and Skin Care

• Trim toenails straight across (not rounded)
• Don't cut cuticles
• Moisturize daily (but not between toes)
• Let a professional handle calluses and thick nails

What Happens During a Diabetic Foot Exam?

Our comprehensive exam includes:

• Sensory testing — Monofilament testing to check for loss of protective sensation
• Circulation assessment — Pulse checks and evaluation of blood flow
• Skin inspection — Thorough examination for cracks, sores, or early ulcers
• Structural evaluation — Checking for deformities and pressure points
• Risk assessment — Classifying your risk level and creating a prevention plan
• Education — Teaching you daily foot care habits and warning signs
