Corns And Calluses

Overview

Corns and calluses are areas of thick, hard skin that form where your skin rubs or presses against something again and again. A callus is usually a broad patch of thickened skin. A corn is a small, focused patch that can feel like a hard lump, often with a tender center.

Very common. Most people get a callus or corn at some point, especially on the feet or hands.

Anyone can get them, but they are more likely if you wear tight or hard shoes, use your hands for repeated work, have a foot shape that rubs, or have diabetes or poor circulation.

Symptoms

Common symptoms

• Thick, rough, or hard skin
• A raised, hard bump that may be painful when pressed
• Yellowish or brownish center in a corn
• Dry, flaky skin around the area
• Pain or tenderness when walking, standing, or using your hands

Symptoms in children

• Children may get calluses from sports, tight shoes, or going barefoot a lot.
• They may not tell you about foot pain, so check their feet if they limp, avoid certain shoes, or seem uncomfortable.
• Corns are less common in children, but they can happen where shoes rub.

Symptoms in older adults

• Older adults may have drier skin, changes in foot shape, reduced feeling in the feet, or poor circulation, so corns can go unnoticed.
• Diabetes and vision problems can make foot self-care harder, so ask for help if needed.
• Painful corns can affect balance and walking, so early care is helpful.

Causes

Main causes

• Repeated rubbing or pressure on the skin
• Shoes that are too tight, too loose, or have hard soles
• Walking barefoot or wearing shoes without socks
• Repeated use of tools or handling objects with your hands
• Foot shape or walking style that puts extra pressure on certain areas

Risk factors

• Ill-fitting shoes, high heels, or thin-soled shoes
• Bunions, hammer toes, or other foot changes
• Diabetes or poor circulation
• Reduced feeling in the feet
• Older age and dry skin
• Jobs or hobbies that involve a lot of standing, walking, or hand work
• Going barefoot often

When to see a doctor

See a doctor urgently if:

• You see signs of infection, such as spreading redness, warmth, swelling, pus, or fever
• You have a new open sore or ulcer, especially if you have diabetes
• Bleeding does not stop or the area is very painful
• You have sudden severe foot pain or cannot put weight on your foot

Book a routine appointment if:

• A corn or callus is painful or keeps coming back
• Self-care has not helped after a few weeks
• You have diabetes, poor circulation, or reduced feeling in your feet
• You notice a change in foot shape or how you walk
• You are not sure whether the hard skin is a corn, callus, wart, or something else

Diagnosis

A healthcare provider usually diagnoses a corn or callus by asking about your symptoms and looking at your skin and feet. They may check your shoes, how you walk, and the feeling and blood flow in your feet to find the cause.

Tests that may be done

• Usually no tests are needed.
• Your clinician may check feeling and blood flow in your feet.
• Rarely, imaging or a skin check may be done if another condition is suspected.

What to expect at your appointment

The exam is quick and does not usually hurt. Your clinician may give advice on footwear, padding, or foot care, and may refer you to a foot health professional if needed.

Treatment

Treatment aims to reduce pressure and rubbing, soften the hard skin, and protect the area while it heals. It is important not to cut or pick at a corn or callus yourself, especially if you have diabetes or poor circulation.

Self-care at home

• Soak the area in warm water for about 10 to 15 minutes to soften the skin.
• Gently file the hard skin with a pumice stone or foot file after soaking. Do not try to remove it all at once.
• Moisturize dry skin, but avoid putting cream between your toes.
• Wear well-fitting shoes with a roomy toe box and soft soles.
• Use socks or protective padding to reduce rubbing.
• Avoid medicated corn plasters unless a clinician advises them, especially if you have diabetes or poor circulation.
• Do not cut, shave, or use sharp tools on a corn or callus.

Medical treatments

A clinician can gently remove the hard skin with a special tool, which is called debridement. They may also recommend padding, shoe changes, or custom insoles to spread pressure. If another foot problem is causing the rubbing, they may refer you to a foot specialist. They will not usually prescribe medicine for simple corns and calluses.

When is surgery considered?

Surgery is rarely needed for corns and calluses. It may be considered only if a foot deformity keeps causing severe pressure and other treatments have not helped. A foot specialist would discuss the risks and benefits.

Living with this condition

Check your feet or hands regularly, wear comfortable shoes, and take breaks from repeated pressure. If a corn is painful, padding and softer footwear can make daily activities easier while it heals.

Lifestyle tips

• Choose shoes that fit well and have enough room for your toes.
• Wear socks with shoes to reduce friction.
• Use gloves for repeated hand work or hobbies.
• Keep skin moisturized but not wet or macerated.
• Avoid going barefoot on hard surfaces if you are prone to calluses.

Diet and exercise

No special diet is needed for corns and calluses. Regular activity helps circulation and general health, but choose footwear that does not rub. If you have diabetes, work with your healthcare team to manage your blood sugar and check your feet daily.

Mental health and emotional wellbeing

Ongoing foot pain can be frustrating and can affect sleep, mood, and daily activities. Most people improve with simple care. If pain or worry about your feet is getting you down, talk to your healthcare provider. If you are in crisis or having thoughts of self-harm, contact your local emergency number or a local crisis service right away.

Prevention

You can greatly reduce the chance of corns and calluses by wearing well-fitting shoes, using protective padding or gloves, and changing activities that cause repeated rubbing.

Vaccines

There is no vaccine for corns and calluses.

Screening programmes

There is no routine screening test for corns and calluses. Regular foot checks are important if you have diabetes, poor circulation, or reduced feeling in your feet; ask your healthcare team how often you need them.

Complications

If left untreated

• Pain that makes walking or daily tasks harder
• The skin may crack or break, which can let infection in
• People with diabetes or poor circulation can develop foot ulcers, which need prompt care
• Changed walking style may cause strain on other parts of the foot or leg

Long-term outlook

Most corns and calluses improve with simple self-care and better-fitting footwear. They can come back if the pressure or rubbing continues, but they are usually not serious. Getting help early is especially important if you have diabetes or poor circulation.
