Corns are areas of thickened skin that develop in response to repeated pressure or friction. They commonly form on the toes or other parts of the foot that rub against shoes, neighboring toes, or the ground.
At Preferred Footcare, our podiatrists provide professional corn evaluation and treatment in Stamford, Connecticut. We identify what is causing the pressure, relieve painful thickened skin, and recommend ways to reduce the risk of recurrence.
If a corn is painful, keeps returning, or makes it difficult to wear shoes comfortably, call (203) 975-9600 or request an appointment with Preferred Footcare.
Request an AppointmentWhat Are Corns?
A corn is a small, concentrated area of thickened skin that forms when the foot experiences repeated friction or pressure. The skin thickens as a protective response, but the buildup can press into sensitive tissue and become painful.
Corns may develop on top of the toes, along the sides of the feet, between the toes, or in other areas exposed to repeated pressure.
Common types include:
Hard Corns
Hard corns are firm areas of thickened skin with a dense center. They often develop on top of a bent toe or along the outside of the foot where the skin rubs against footwear.
Soft Corns
Soft corns usually form between the toes, where moisture keeps the skin from becoming completely hard. They may appear pale or rubbery and can become painful when neighboring toes press together.
Seed Corns
Seed corns are small, round areas of thickened skin that commonly develop on the bottom of the foot. They may occur individually or in groups.
A corn is different from a callus. Corns are usually smaller and more concentrated, while calluses cover a broader area of skin. Both develop because of repeated pressure or friction.
What Causes Corns?
Corns typically form over an area where the skin experiences ongoing pressure. Treating the thickened skin without correcting the source of pressure may cause the corn to return.
Possible causes include:
- Shoes that are too tight or narrow
- Shoes that are too loose and allow the foot to slide
- High-heeled footwear
- Socks that bunch or create friction
- Wearing shoes without socks
- Hammertoes or other bent-toe deformities
- Bunions
- Prominent bones or joints
- Toes that rub against each other
- Abnormal walking patterns
- Uneven pressure across the foot
- Repetitive activity
- Loss of natural cushioning under the foot
A corn on top of a toe may be related to a hammertoe rubbing against the shoe. A soft corn between the toes may develop when the toe bones press together. Corns under the foot may result from uneven weight distribution.
A podiatric evaluation can identify the source of pressure and determine whether footwear, foot structure, or another condition is contributing to the problem.
Corn Symptoms
Corns may be painless at first but become increasingly uncomfortable as the thickened skin grows or pressure continues.
Common signs and symptoms include:
- A small, raised area of thickened skin
- A hard or waxy center
- Pain when direct pressure is applied
- Tenderness while walking
- Discomfort when wearing shoes
- Dry or flaky skin around the affected area
- A soft, pale area between the toes
- Redness or irritation
- Burning around the pressure point
- Recurring thickened skin in the same location
A corn may sometimes be confused with a plantar wart. Corns generally develop over pressure points, while warts are caused by a viral infection. Because the treatments are different, avoid using over-the-counter products until the area has been properly identified.
When to Seek Professional Care
Schedule an evaluation if:
- The corn is painful or keeps returning
- The area becomes red, swollen, or warm
- You notice bleeding or drainage
- The skin breaks down
- You are unsure whether it is a corn or wart
- You have diabetes, poor circulation, or reduced sensation
- The corn interferes with walking or wearing shoes
Patients with diabetes or circulation problems should not attempt to cut, shave, or chemically remove corns at home. Even a minor skin injury can develop into a more serious wound or infection.
How Corns Are Diagnosed
Corns can often be diagnosed through a physical examination. The podiatrist will evaluate the thickened skin and identify the pressure or friction causing it.
The evaluation may include:
- Examining the location and appearance of the lesion
- Checking whether direct pressure causes pain
- Looking for corns between the toes
- Evaluating nearby joints and bones
- Checking for bunions or hammertoes
- Assessing foot structure
- Observing how you stand and walk
- Reviewing the fit and condition of your shoes
- Checking circulation and sensation
- Looking for signs of a wound or infection
An X-ray may be recommended if the podiatrist suspects that a prominent bone, arthritis, hammertoe, or another structural condition is causing repeated pressure.
The examination can also help distinguish a corn from a callus, plantar wart, cyst, foreign body, or another skin condition.
Corn Treatment Options
Treatment focuses on relieving pain, reducing the thickened skin, and addressing the pressure that caused the corn.
Your treatment plan may include:
Professional Corn Reduction
The podiatrist may carefully reduce the thickened skin using sterile instruments. This can relieve pressure and discomfort, but the corn may return if its underlying cause is not addressed.
Do not attempt to cut or shave a corn at home. Using a razor, scissors, or another sharp instrument can damage healthy skin and lead to bleeding or infection.
Footwear Changes
Shoes should provide enough length, width, and depth for the toes. A wider toe box can reduce rubbing against a corn and accommodate bent or prominent toes.
Avoid shoes that are tight, pointed, or place excessive pressure on the affected area.
Padding
Protective padding may be used to cushion the corn and reduce friction. The shape and placement of the padding are important because pressure placed directly over the corn may make it more painful.
Toe Spacers
A toe spacer may help reduce pressure when a soft corn develops between the toes. The podiatrist can determine whether this option is suitable for your foot structure.
Custom Orthotics
Custom orthotics may be recommended when abnormal foot movement or uneven weight distribution contributes to recurring corns. They can help support the foot and redirect pressure away from the affected area.
Skin Care
Moisturizing dry skin may help reduce cracking around areas of thickened skin. Do not apply moisturizer between the toes unless directed, as excess moisture can contribute to skin problems.
Treatment of an Underlying Deformity
A recurring corn may be caused by a hammertoe, bunion, prominent bone, or another structural problem. Treating the related condition may help reduce the pressure responsible for the corn.
Surgery
Surgery may be considered when a structural deformity causes persistent pain or recurring corns that do not improve with appropriate conservative treatment.
The recommended procedure will depend on the underlying bone or joint problem. Surgery is not necessary for most corns.
Preventing Corns From Returning
Corns often return when the source of pressure remains. Preventive care should focus on reducing rubbing and improving the way pressure is distributed across the foot.
Helpful measures include:
- Wearing properly fitted shoes
- Choosing shoes with a wider toe box
- Avoiding footwear that rubs against prominent joints
- Wearing clean, well-fitting socks
- Using padding or toe spacers as directed
- Keeping the feet clean and dry
- Moisturizing dry skin as appropriate
- Inspecting the feet regularly
- Using prescribed custom orthotics
- Addressing bunions and hammertoes
- Replacing worn-out footwear
- Scheduling professional care for recurring corns
Patients with diabetes should inspect their feet daily and contact their healthcare provider if they notice redness, drainage, broken skin, or a new pressure area.
Frequently Asked Questions About Corns
What is the difference between a corn and a callus?
A corn is usually smaller and has a concentrated center that may become painful under direct pressure. A callus generally covers a wider area and forms where pressure is distributed over a larger surface.
Can I remove a corn myself?
Do not cut or shave a corn at home. This can damage healthy skin and cause bleeding or infection. Professional treatment is especially important if you have diabetes, poor circulation, or reduced sensation.
Do over-the-counter corn removers work?
Some products contain acids that remove layers of skin, but they can also damage healthy tissue. Ask a podiatrist before using these products, particularly if you have diabetes or circulation problems.
Why does my corn keep returning?
A corn may return when the pressure causing it has not been corrected. Tight shoes, hammertoes, bunions, prominent bones, or abnormal weight distribution may contribute to recurrence.
Are corns contagious?
No. Corns develop because of pressure and friction. They are not caused by a virus and cannot spread from one person to another.
Can custom orthotics help prevent corns?
Custom orthotics may help when uneven pressure or abnormal foot movement contributes to recurring corns. They are not necessary for every patient.
When should I see a podiatrist?
Schedule an appointment if the corn is painful, keeps returning, affects walking, or shows signs of skin breakdown. Seek prompt care if you have diabetes and notice any new foot lesion.
