Corn On Foot: Causes, Symptoms, Treatment & Prevention

What is foot corn?

Corn On Foot is a small, thickened area of skin that mostly appears on or between the toes, on the ball of the foot, or on the sides of the feet. Corn On Foot is usually caused by repeated friction or pressure on the skin, often as a result of wearing ill-fitting shoes or engaging in activities that put stress on the feet. They can be uncomfortable or painful, especially when pressure is applied to them.

What are the symptoms of Corn On Foot?

The common symptoms of foot corns experienced by the patients are:

• Thickened and rough skin: Corns appear as thickened, hardened skin that may have a rough or waxy texture. The skin over the corn may also be yellowish or grayish in color.
• Raised bump: Corns often form a raised bump of thickened skin. The bump may be circular or conical in shape and can vary in size.
• Pain or discomfort: Corns can cause pain or discomfort, especially when pressure is applied to them. Walking or wearing tight shoes may exacerbate the pain.
• Tenderness: The skin around the corn may become tender or sensitive to touch. Direct pressure on the corn can evoke pain.
• Skin discoloration: In some cases, corns may cause skin discoloration, appearing red or inflamed due to irritation or inflammation of the surrounding tissues.

Corns are generally localized and may have a well-defined border. They are different from calluses, which are larger areas of thickened skin that develop over a broader surface area.

If you suspect a foot corn or are experiencing foot pain or discomfort, it is advisable to consult a healthcare professional or a podiatrist for an accurate diagnosis and appropriate foot corn treatment. They can guide managing corns and recommend measures to prevent further friction or pressure on the affected area.

What are the causes of Corn On Foot?

Corn On Foot is primarily caused by repeated pressure or friction on the skin. The most common causes of foot corn are discussed below:

• Improper footwear: Wearing shoes that are too tight, narrow, or have high heels can increase pressure and friction on certain areas of the feet. This can lead to the development of corns, especially on the toes or sides of the feet.
• Abnormal foot anatomy: Certain foot deformities or structural abnormalities, such as hammertoes or bunions, can cause uneven distribution of pressure on the feet. This can result in areas of increased friction and corn formation.
• Excessive rubbing or friction: Activities or occupations that involve repetitive rubbing or friction on the feet can contribute to corn development. Examples include playing certain sports, walking long distances, or wearing poorly cushioned socks.
• Lack of foot protection: Walking barefoot or wearing thin-soled shoes can expose the feet to more pressure and friction, increasing the risk of corn formation.
• Abnormal gait or foot function: Irregular walking patterns or biomechanical abnormalities, like overpronation or supination, can create excessive pressure on specific areas of the feet. This can lead to the development of corns over time.

Corns are the body’s natural defense mechanism to protect the skin from excessive pressure or friction. However, if the underlying cause is not addressed, corns may persist or recur even after they are treated.

Types of Corn On Foot

Foot corns, also known as helomas, develop on the foot as a result of pressure or friction. There are several types of foot corns experienced by the patients, including:

• Hard corns (heloma durum): These are the most common type of corns and are majorly found on the tops or sides of the toes or on the balls of the feet. Hard corns have a dense and compact center surrounded by a ring of hardened skin. They can be quite painful, especially when pressure is applied.
• Soft corns (heloma molle): Soft corns are usually found between the toes, particularly between the fourth and fifth toes. They are softer and more moist than hard corns and have a whitish appearance. Soft corns can be painful and prone to infection due to the moisture between the toes.
• Seed corns: Seed corns are tiny, discrete corns that often occur on the bottom of the foot. They are often painless but can cause discomfort when pressure is applied. Seed corns are believed to result from blocked sweat ducts or friction.
• Vascular corns: Vascular corns, also known as neurovascular corns, occur when blood vessels grow into a corn. They can be more painful than regular corns and may require medical attention.

While both corns and calluses develop from pressure or friction on the skin, corns have a more defined center and are typically smaller and more painful than calluses.

Diagnostic Tests and Health Screenings Done Before Foot Corn Removal

Before considering foot corn removal, the doctor will conduct a thorough examination of your feet to assess the corns and determine the most appropriate treatment approach. The specific tests and screenings can vary based on individual circumstances, but here are some common ones:

• Physical examination: The healthcare professional will visually inspect your feet and corns, looking for signs of infection, inflammation, or other underlying issues. They may also assess your foot structure and gait to identify potential contributing factors to the corns.
• Medical history: The healthcare professional will ask you questions about your medical history, including any previous foot conditions, surgeries, or chronic illnesses that may affect your feet. They may also inquire about your lifestyle, occupation, and footwear choices to identify potential causes or aggravating factors for the corns.
• Foot pressure analysis: In some cases, the healthcare professional may use pressure mapping technology to analyze the distribution of pressure on your feet while standing or walking. This can help identify areas of excessive pressure that contribute to corn formation.

• X-rays: X-rays may be recommended if there is suspicion of an underlying bone abnormality or joint condition that is contributing to the corns. X-rays can provide detailed images of the bones and joints in the feet.

Blood tests: Blood tests may be suggested if there are concerns about underlying systemic conditions like diabetes or circulation problems, which can affect foot health.

Treatment Options for Foot Corn Removal

There are several foot corn treatment options available, ranging from home remedies to medical and surgical interventions. The choice of foot corn treatment depends on the severity of the corn, the presence of any underlying conditions, and individual preferences. It is to be noted that while these treatments can help remove the corn, it is important to address the underlying cause to prevent recurrence. 

Here are some common foot corn treatment options available for foot corn removal:

• Non-medicated pads: Over-the-counter non-medicated pads, such as corn pads or donut-shaped pads, can provide cushioning and reduce pressure on the corn. These pads can be applied directly to the corn to alleviate discomfort.
• Salicylic acid: Salicylic acid is a common ingredient in over-the-counter corn removal products. It softens the corn and helps to gradually remove the dead skin layers. These products usually come in the form of creams, pads, or plasters. Follow the instructions carefully when using salicylic acid products and avoid applying them to healthy skin as it can cause irritation.
• Surgical removal: If conservative treatments are unsuccessful or the corn is particularly large or problematic, the doctor may recommend surgical removal. This procedure involves numbing the area with local anesthesia and surgically excising the corn. Surgical removal is usually a last resort when other treatments have failed.

What happens if Corn On Foot is not treated?

If a foot corn is left untreated, it can lead to various complications and discomfort. Here are some potential consequences of not treating a foot corn:

• Pain and discomfort: Foot corns can cause pain and discomfort, especially when pressure is applied. This can make walking or wearing shoes uncomfortable and may affect your daily activities and quality of life.

• Increased size and depth: If left untreated, foot corns can continue to grow in size and become deeper. This can result in more pain and difficulty in removing the corn in the future.
• Infection: Corns can create a break in the skin, which can serve as an entry point for bacteria. If the corn becomes infected, it can lead to redness, swelling, warmth, pus formation, and increased pain. In severe cases, cellulitis (a skin infection) or abscess formation may occur.
• Ulceration: Prolonged pressure and friction on corn can lead to the development of an ulcer. Ulcers are open sores that can be susceptible to infection and slow healing. Individuals with diabetes or poor circulation are particularly prone to developing foot ulcers, and these can be serious and difficult to treat.
• Changes in gait and posture: The presence of foot corns can alter your gait and posture as you try to avoid putting pressure on the affected areas. This can lead to imbalances in the body and increase the risk of developing other foot, leg, or back problems.

• Chronic conditions: Foot corns can be a symptom of an underlying foot deformity, such as a bunion or hammertoe. If the underlying condition is not addressed, the corns are likely to recur even after removal.

It is important to seek foot corn treatment to alleviate pain, prevent complications, and address any underlying issues. A healthcare professional or podiatrist can provide appropriate guidance and recommend the best treatment options for your specific situation.

How to prevent Corn On Foot?

Preventing foot corns involves minimizing the factors that contribute to their development. Here are some tips to help prevent foot corns:

• Wear properly fitting shoes: Choose shoes that provide adequate room for your toes and do not squeeze or rub against your feet. Avoid shoes that are too tight or too loose. Opt for shoes made of breathable materials that allow proper ventilation.
• Use cushioning and protective measures: Consider using cushioning pads or insoles to provide extra padding and reduce friction on areas prone to corns. These can help distribute pressure more evenly and protect your feet from developing corns.
• Wear socks: Wear socks made of breathable materials, such as cotton or moisture-wicking fabrics, to help reduce friction and keep your feet dry. Avoid socks with seams or ridges that can cause irritation.
• Practice good foot hygiene: Keep your feet clean and dry. Wash your feet regularly with mild soap and warm water, and make sure to thoroughly dry them, especially between the toes, as moisture can contribute to the development of soft corns.
• Moisturize your feet: Apply moisturizer to your feet to keep the skin soft and supple. This can help prevent dryness and cracking, which can lead to corn formation.
• Avoid excessive pressure and friction: Minimize activities that put excessive pressure or friction on your feet, such as prolonged periods of standing or activities that involve repetitive rubbing or pounding motions. If you engage in such activities, take frequent breaks and give your feet a rest.
• Address foot deformities: If you have foot deformities like bunions or hammertoes, it’s important to address them with proper footwear, orthotics, or other interventions. These conditions can increase the risk of developing corns, so managing them effectively is crucial.

By following these preventive measures, you can reduce the likelihood of developing foot corns and maintain healthy feet.
