Corns / Calluses
Overview: Corns and calluses are common skin conditions of the feet that can be easily treated, but good foot care and properly fitted shoes can prevent them from developing.¹ A corn is a small, painful, inflamed area of thick skin. A callus is bigger and not usually painful.²
Symptoms: Corns and calluses are most often found on the balls of the feet or the tops of the toes, as well as on the heels and along the sides of toenails. If not relieved, pressure may produce inflammation resulting in pain, swelling and redness. ‘Soft’ corns can also form between the toes, where the skin is moist from sweat or inadequate drying – these appear white and rubbery.¹ Calluses tend to look pale yellow and feel less sensitive to touch, while corns are smaller with a defined, painful core.
Causes: Corns and calluses are caused by abnormalities in bone structure or from pressure from footwear or walking.³ When footwear creates extra friction on areas of the foot, the body responds by thickening the surface layer of the skin. Calluses and corns can also be signs of underlying problems and early warnings of more complex foot disorders. Everyone can get them, especially the elderly, who lose fatty tissue and flexibility with age, and those who work in occupations that keep them on their feet.³
Lifestyle options: Pay attention to your feet, keep them moisturised and ensure you have properly fitted shoes – especially if you spend a lot of time on your feet or are elderly.¹ To help your corn or callus heal, wear protective gloves for manual or outdoor tasks, wear well-fitting, comfortable, flat footwear, and use a protective adhesive over the corn or callus. Your GP may advise you to gently file the affected skin and use a soothing cream.² Over-the-counter remedies such as corn paint or plasters tend to treat symptoms, not the underlying problem – a podiatrist can remove the hard skin, apply padding, and assess footwear and biomechanics for longer-term relief. HealthDirect Never attempt to cut a corn yourself, especially if you have diabetes.
