16896 Corns And Calluses

Overview

Corns and calluses are thick, hardened layers of skin that form when your skin tries to protect itself from repeated pressure or rubbing. They are usually not serious and often improve with simple skin care and changes to footwear.

Yes. Corns and calluses are very common, especially among adults and people who spend a lot of time on their feet.

Anyone can develop corns and calluses, but they are more common in older adults, athletes, people with foot deformities, and those who wear tight shoes or high heels.

Symptoms

Common symptoms

• Hard, thickened area of skin
• Small, round bump (corn) usually on the top or side of a toe
• Larger, flat patch (callus) often on the heel or ball of the foot
• Flaky or dry skin
• Tenderness or pain under the skin when pressure is applied

Symptoms in children

• Corns and calluses are less common in children but can appear if shoes are too small.
• A child may complain of a 'pebble in the shoe' or pain when walking.

Symptoms in older adults

• Skin becomes thinner and loses natural cushioning, so calluses can form more easily.
• Diabetes or poor circulation may make corns and calluses less noticeable until they become irritated.

Causes

Main causes

• Repeated friction or rubbing from shoes or activities
• Pressure from standing or walking for long periods
• Tight, ill-fitting shoes or high heels
• Barefoot walking on hard surfaces
• Toe deformities like hammertoes or bunions

Risk factors

• Age — older skin is less pliable
• Athletic activity that involves repetitive motion
• Occupations that require standing or walking
• Foot deformities
• Diabetes or poor circulation
• Excess weight

When to see a doctor

See a doctor urgently if:

• If you have diabetes, peripheral artery disease, or a weakened immune system, see a doctor for any corn or callus, especially if the skin is broken.

Book a routine appointment if:

• If corns or calluses are painful despite home care
• If they keep coming back
• If you are unsure whether the growth is a wart or something else

Diagnosis

A doctor or podiatrist (foot specialist) can usually diagnose corns and calluses by looking at your feet. They may press on the area to check for tenderness and ask about your shoes and activities.

Tests that may be done

• Usually no tests are needed.
• In some cases, a doctor may scrape a little skin to tell it apart from a wart or other growth.
• If you have diabetes, your doctor may check the blood flow and sensation in your feet.

What to expect at your appointment

The visit is simple and typically takes only a few minutes. The doctor will give you advice on footwear, padding, and safe ways to file down thick skin. No needles or blood tests are usually involved.

Treatment

Treatment focuses on removing the thick skin and, more importantly, stopping the cause. Most cases can be managed with home care and better footwear.

Self-care at home

• Soak the area in warm water for about 5 to 10 minutes to soften the skin.
• Use a pumice stone or foot file gently in one direction to rub away dead skin. Do not cut the skin.
• Apply a thick moisturizer, such as petroleum jelly, to keep the skin soft.
• Use padded insoles, heel cups, or protective corn plasters (but check they do not contain medicines that can irritate skin).
• Wear shoes with a wide toe box and cushioned soles.

Medical treatments

A doctor or podiatrist can pare down thick calluses with a sterile blade. They may also recommend custom orthotic insoles to help spread weight more evenly across your foot. Over-the-counter medicated pads are available, but they can harm healthy skin and are not safe for everyone, especially people with diabetes or poor circulation. Always ask a healthcare professional before using them.

When is surgery considered?

Surgery is almost never needed for corns or calluses. It may be considered only if a foot deformity such as a hammertoe or bunion is the root cause and conservative treatment has not helped.

Living with this condition

Check your feet daily for any changes. Keep your skin clean and moisturized. Choose comfortable shoes with soft soles and enough room for your toes.

Lifestyle tips

• Rotate shoes so you do not wear the same pair every day.
• Wear socks that fit well and wick moisture away.
• If you stand for long periods, take short breaks to sit and shift your weight.
• For hand calluses, wearing gloves during repetitive work can help.

Diet and exercise

A balanced diet and a healthy weight help reduce pressure on your feet. Gentle exercises like walking, swimming, and stretching keep your feet flexible. Avoid high-impact activities if they cause pain.

Mental health and emotional wellbeing

Persistent foot pain can be frustrating and may affect your sleep or daily activities. It can also make it harder to stay physically active. It is normal to feel annoyed or worried, but know that simple changes usually bring improvement.

Prevention

Yes, in most cases. Preventing friction and pressure is the key to avoiding corns and calluses.

Vaccines

There are no vaccines that prevent corns and calluses.

Screening programmes

There is no formal screening test. But if you have diabetes, your healthcare team should check your feet at least once a year as part of routine care.

Complications

If left untreated

• The skin can crack and become infected (cellulitis).
• Pain can change the way you walk, possibly leading to knee, hip, or back problems.
• In people with diabetes, even a small break in the skin can lead to a serious foot ulcer.

Long-term outlook

With proper footwear, skin care, and occasional professional treatment, corns and calluses usually improve and can often be prevented. Even when they return, they can be managed comfortably.
