- Nerve damage can make blisters, burns and cuts painless, while poor circulation and high glucose can make infection and healing problems more likely.
- Check the tops, soles, heels and between toes daily for blisters, cuts, cracks, redness, swelling, drainage, callus or colour/temperature change.
- Do not cut corns/calluses yourself, use strong corn plasters on numb feet, soak in very hot water or apply unverified remedies to open wounds.
Why visible problems can still be underestimated
Diabetes can reduce sensation and healing in the feet. Learn why daily checks matter and what changes need medical review.
Skin can show infection, circulation problems, nerve damage or cancer-related change. The absence of severe pain does not prove a lesion or wound is harmless.
What to look for
Nerve damage can make blisters, burns and cuts painless, while poor circulation and high glucose can make infection and healing problems more likely.
Track change in size, colour, warmth, swelling, drainage, sensation and healing. A dated photograph can help show evolution but cannot replace medical examination.
What safe early care means
Check the tops, soles, heels and between toes daily for blisters, cuts, cracks, redness, swelling, drainage, callus or colour/temperature change.
Keep wounds clean and protected, avoid trauma and address underlying problems such as diabetes or poor circulation. Persistent or worsening problems deserve professional assessment.
Where TCM may fit
Do not cut corns/calluses yourself, use strong corn plasters on numb feet, soak in very hot water or apply unverified remedies to open wounds.
Do not needle, scrape, cup, massage or apply irritating herbal preparations over active infection, open wounds or suspicious changing lesions. Diagnosis and tissue safety come first.
Red flags that should not wait
Spreading redness, warmth, pus, bad smell, fever, black or blue tissue, deep ulcer or a rapidly worsening wound needs prompt medical care.
