Top of Foot Hurts After Running? Causes, Injuries, and How to Treat It

Corns and bunions are two very different foot conditions, yet many people confuse them because both can cause pain, pressure, and difficulty wearing shoes. One affects the skin, the other affects the bone and joint, but without understanding the difference, it’s easy to misinterpret symptoms.

Understanding the difference between a corn and a bunion helps patients choose the right treatment and avoid unnecessary discomfort. In this guide, we break down how each condition develops, the symptoms to watch for, and the most effective treatment options.

What Is a Corn?

A corn is an area of thick, hardened skin that develops in response to pressure or friction. Unlike bunions, corns do not involve the bone or joint, they form on the surface of the skin.

Common locations include:

• Tops of toes
• Sides of toes
• Between the toes (soft corns)
• The bottom of the foot (seed corns)

Why Corns Develop

Corns form as the skin’s natural way of protecting itself from irritation. This often happens due to:

• Tight or narrow shoes
• High heels
• Toe deformities such as hammertoes or claw toes
• Abnormal gait patterns
• Repetitive friction or rubbing

Corns are especially common when a shoe repeatedly rubs against a prominent toe joint or bony area.

Symptoms of Corns

Corns may be small, but they can cause significant discomfort. Symptoms often include:

• A small, hard bump of thickened skin
• Pinpoint, localized pain
• Tenderness when walking or wearing shoes
• Dry, flaky, or waxy skin over the lesion

Because they form where pressure is greatest, corns may appear on top of bunions, contributing to the confusion between the two conditions.

What Is a Bunion?

A bunion (hallux valgus) is a progressive deformity of the big toe joint. Instead of being a skin lesion, a bunion occurs when the big toe shifts inward toward the second toe. This causes the joint at the base of the big toe to protrude outward, forming a visible bump.

Why Bunions Develop

Several factors can contribute to bunion formation, including:

• Genetics (the strongest influence)
• Flat feet or unstable arches
• Joint hypermobility
• Tight or pointy footwear
• Arthritis
• Neuromuscular conditions

A key difference from corns is that bunions represent structural changes, not thickened skin.

Symptoms of Bunions

Symptoms usually progress over time and may include:

• A visible bump at the base of the big toe
• Aching or throbbing pain, especially after walking
• Redness or swelling around the joint
• Difficulty finding comfortable shoes
• Stiffness or reduced mobility in the big toe

Bunions may also cause calluses or corns because the protruding joint creates abnormal pressure inside shoes.

What’s the Difference Between a Corn and a Bunion?

Although both conditions can cause discomfort in similar areas, they are fundamentally different. This comparison can help clarify:

Because both conditions can appear together and cause pain near the toes, many people lump them together as corns and bunions on feet, but distinguishing between them is essential for choosing the right treatment.

What Causes Corns and Bunions on Feet?

While they are different conditions, corns and bunions often share contributing factors such as:

• Poorly fitting shoes
• Abnormal pressure on the toes
• Foot structure issues like flat feet or hammertoes
• Biomechanical imbalances during walking

The difference lies in the body’s response:

• Corns respond to friction by thickening the skin. ‍
• Bunions respond to joint misalignment by changing bone position.

Treatment Options for Corns

Conservative Care

• Wear wide, supportive shoes
• Use protective pads or toe sleeves
• Gently moisturize thickened skin
• Use a pumice stone (with caution)
• Toe spacers to reduce rubbing

Professional Care

Because corns often return without addressing the underlying cause, a podiatrist may recommend:

• Safe trimming and debridement (never attempt at home)
• Custom orthotics to reduce pressure
• Treatment for hammertoes or toe deformities
• Footwear recommendations

Important: Avoid medicated corn pads unless advised; salicylic acid can burn healthy skin, especially in diabetic patients.

Treatment Options for Bunions

Non-Surgical Options

• Wider footwear
• Bunion pads or cushions
• Ice and anti-inflammatory measures
• Splints or toe spacers for mild cases
• Custom orthotics to improve alignment and reduce pressure
• Activity modification

Surgical Options

Surgery is the only way to permanently correct a bunion. It may be recommended if:

• Pain persists despite conservative care
• The deformity worsens
• Walking becomes difficult
• The toe joints become stiff or arthritic

Modern bunion surgery techniques are more precise and often allow quicker recovery with less postoperative discomfort.

When to See a Podiatrist

You should schedule an evaluation if:

• Pain interferes with your daily activities
• A corn keeps returning
• A bump near the big toe gets larger or more painful
• Shoes are increasingly uncomfortable
• There is swelling, redness, or signs of infection
• You have diabetes or poor circulation
• You’re unsure whether the problem is a corn or a bunion

A podiatrist can identify the root cause and create a personalized treatment plan before the problem worsens.

Protect Your Foot Health with Proper Diagnosis

Corns and bunions may affect similar areas of the foot, but they require very different treatments. Early evaluation helps prevent chronic pain, recurring corns, or progressive bunion deformity.
