A small hard area with a central core
Condition guide
Foot Corn
A small, hardened area of skin that develops where repeated pressure or friction is concentrated.
Do not cut a corn yourself or use medicated corn plasters if you have diabetes, poor circulation, reduced sensation or fragile skin.
Understanding the concern
The visible symptom is only part of the clinical picture.
A small, hardened area of skin that develops where repeated pressure or friction is concentrated. Corns are usually a response to repeated friction or pressure from footwear, a toe deformity or a particular walking pattern. Removing the thick skin without addressing the pressure source often leads to recurrence.
Clinical context
Symptoms and signs
Small changes deserve attention.
Sharp pain when pressure is applied
Repeated rubbing in the same shoe
Tender skin between or on top of toes
Causes and risk factors
Several factors can come together.
A corn is a localised response to repeated pressure or friction, commonly from footwear, toe shape or a particular loading pattern.
Tight or narrow shoes
Toe deformities
Repeated friction during walking
Diabetes, poor circulation or reduced sensation
When to seek prompt care
Do not wait for symptoms to become severe.
Do not cut a corn yourself or use medicated corn plasters if you have diabetes, poor circulation, reduced sensation or fragile skin.
MMC evaluation
Assessment follows the whole clinical picture.
A clinician checks whether the lesion is a corn, callus, wart or another condition and identifies the pressure source before treatment.
Relevant care pathways
Care is matched to the condition and the person.
Remove pressure safely: Professional care can reduce painful hard skin without unsafe self-cutting.
Correct the source: Footwear, padding and orthotic advice can reduce recurrence.
Protect at-risk feet: People with diabetes should avoid acid plasters and seek podiatry advice.
Protect your feet between reviews.
Keep changes protected, avoid unadvised self-treatment and seek advice if symptoms worsen or do not improve.
The next step should be clear.
A timely assessment helps match care to the diagnosis, risk and practical needs of the person.
Common questions
When should I seek urgent care?+
Seek prompt medical advice for spreading redness, a new or worsening wound, discharge, fever, black or blue skin, sudden swelling, or a foot that becomes hot, cold or painful. If you feel very unwell, seek emergency care.
Can I treat this at home?+
Avoid cutting, draining, paring or applying unadvised products. The safest next step depends on your skin health, circulation, sensation and medical history.
What should I bring to my appointment?+
Bring recent reports, your medication list, photographs or details of changes over time, and the footwear you use most often when relevant.
