Overview: Why Winter Foot Care Matters
Diabetes can affect the feet in two 
important ways:
Remember
• Nerve damage may reduce A foot problem may be 
sensation. serious even if it does not 
hurt. Check both feet 
• Reduced blood flow can slow healing. every day and seek care 
early for new wounds or 
changes.
Winter dryness, cold conditions, and 
unsuitable footwear may add 
challenges.

Learning Objectives
Define diabetic foot problems and explain why winter may increase foot-care risks.
Recognize common warning signs, including numbness, skin cracks, color changes, 
pain, and slow-healing wounds.
Describe practical foot-care steps and know when urgent medical assessment is 
needed.

1. Understanding Diabetic Foot Problems
Diabetic foot problems can develop when diabetes-related nerve damage (peripheral 
neuropathy) reduces sensation and when reduced blood flow (peripheral artery disease) limits 
the delivery of oxygen and nutrients to tissues.
Cold weather and dry air can make feet feel colder and skin more prone to cracking. Reduced 
activity and unsuitable footwear may add to the risk. Winter itself does not necessarily worsen 
nerve damage, but it can make existing foot problems easier to miss or harder to manage.

2. Numbness, Tingling, or Reduced Sensation
People may notice numbness, pins-and-needles, or reduced ability to feel pain, 
pressure, or temperature. An injury, blister, or burn can go unnoticed when sensation 
is reduced.
Safety point: do not use hot-water bottles, heating pads, or very hot water to warm 
numb feet. Check bath water with a safe method, not with the feet.

3. Cold Feet and Circulation Changes
Feet that remain unusually cold may be related to circulation problems, but cold feet alone do 
not prove poor circulation. Compare both feet and watch for new changes in skin temperature, 
color, or comfort.
Sudden coldness in one foot, especially with severe pain, pale/blue color, numbness, 
or weakness, may be an emergency and needs immediate medical attention.

4. Dry Skin, Cracks, and Calluses
Cold, dry air can contribute to rough skin, cracked heels, and fissures. Cracks can 
provide an entry point for germs. Thick calluses can hide pressure damage or an 
ulcer underneath.
Wash feet gently and dry carefully, especially between the toes. Apply moisturizer to dry skin, 
but avoid putting it between the toes. Do not cut calluses or use chemical corn removers 
yourself.

5. Swelling and Skin-Color Changes
New swelling, redness, unusual warmth, blue or black discoloration, or a change in the shape of 
the foot needs prompt assessment. These signs may be associated with infection, injury, 
inflammation, or circulation problems.
A red, hot, swollen foot—sometimes with little pain—can be a sign of a serious 
diabetic foot complication. Avoid putting weight on it and seek urgent clinical advice.

6. Pain, Burning, or Night-Time Discomfort
Burning, shooting pain, aching, or tingling may be linked to diabetic nerve damage. 
Pain can occur even when some sensation is reduced.
Persistent or worsening pain should be assessed by a healthcare professional, 
particularly if it occurs with a wound, color change, swelling, or temperature 
difference.

7. Cuts, Blisters, Ulcers, and Slow Healing
Small cuts, blisters, punctures, or sores may heal slowly when circulation is poor or 
blood glucose is high. A wound may become infected without causing much pain if 
sensation is reduced.
Seek prompt medical care for any open wound, blister that is worsening, pus, spreading redness, 
bad smell, fever, or a wound that is not healing. Do not rely on home remedies or wait for severe 
pain.

8. Winter Foot-Care Checklist
Inspect the tops, soles, heels, and between the toes every day; use a mirror or ask 
for help if needed.
Wash with lukewarm—not hot—water and dry gently. Moisturize dry skin, avoiding the 
spaces between toes.
Wear well-fitting shoes and clean, dry socks. Check inside shoes for stones, rough 
seams, or objects before wearing them.
Keep feet warm with socks and appropriate footwear; avoid direct heat sources and 
do not walk barefoot, indoors or outdoors.

9. When to Get Medical Help
URGENT / SAME DAY: a new ulcer or open wound; spreading redness; pus; a hot, 
swollen foot; unexplained color change; or a wound with worsening pain.
EMERGENCY: sudden severe foot pain, a suddenly cold/pale/blue foot, black tissue, 
rapidly spreading infection, or symptoms with fever or feeling very unwell. Seek 
emergency care.
People with diabetes should not wait for pain to appear, because nerve damage can 
reduce pain sensation.

Key Terms
Peripheral neuropathy: damage to nerves, often causing numbness, tingling, or 
burning.
Peripheral artery disease: reduced blood flow through arteries, which can impair 
tissue health and healing.
Foot ulcer: an open sore or wound on the foot.
Callus: an area of thickened skin caused by repeated pressure or friction.

Summary and Review Questions
Key message: daily inspection, suitable footwear, safe warming, glucose 
management, and early clinical assessment help lower the risk of serious diabetic 
foot complications.
Review: (1) Name four warning signs of diabetic foot problems. (2) Why should moisturizer not 
be placed between the toes? (3) What changes need urgent assessment? (4) Why can a wound 
be serious even if it is not painful?

Take-Home Message
Inspect daily. Protect from cold safely. Wear well-fitting 
footwear. Treat wounds early. Never ignore sudden 
color, temperature, swelling, or skin changes.
