Summary about Disease
Interdigital corns, also known as soft corns, are painful, whitish, rubbery lesions that develop between the toes, most commonly between the fourth and fifth toes. They are caused by pressure and friction, often exacerbated by moisture in the interdigital space. Unlike hard corns, soft corns remain pliable due to the damp environment.
Symptoms
Pain or discomfort between the toes, particularly when wearing shoes.
A soft, whitish, or grayish lesion between the toes, often rubbery in texture.
Inflammation or redness around the corn.
Pain when pressure is applied to the area.
Sometimes, a burning sensation.
Causes
Pressure and Friction: Ill-fitting shoes, especially shoes that are too narrow or pointed.
Bone Spurs: Underlying bone abnormalities that cause pressure on the skin.
Toe Deformities: Hammertoes, claw toes, or other toe deformities can increase friction.
Excessive Sweating: Moisture between the toes softens the skin, making it more susceptible to corn formation.
Medicine Used
Salicylic Acid: Over-the-counter medicated pads or liquids containing salicylic acid help to soften and remove the corn. Use with caution, especially for individuals with diabetes or poor circulation.
Padding: Non-medicated corn pads can cushion the area and reduce friction.
Antifungal Medications: If a fungal infection is present, antifungal creams or powders may be prescribed to control the infection and prevent further irritation.
Antibiotics: In rare cases where a soft corn becomes infected, oral or topical antibiotics may be necessary.
Prescription-strength keratolytics: A podiatrist may prescribe stronger medications to remove the corn.
Is Communicable
No, interdigital corns are not communicable. They are not caused by a virus, bacteria, or fungus that can be spread from person to person.
Precautions
Wear Properly Fitting Shoes: Choose shoes with a wide toe box that allows your toes to move freely.
Use Padding: Apply non-medicated corn pads or cushions to protect the affected area.
Keep Feet Dry: Dry thoroughly between the toes after bathing or swimming. Use absorbent foot powder to help absorb moisture.
Maintain Good Foot Hygiene: Wash your feet daily with soap and water.
Trim Toenails Properly: Cut toenails straight across to prevent ingrown toenails, which can contribute to pressure between the toes.
See a Podiatrist: If the corn is painful or does not improve with home treatment, consult a podiatrist.
How long does an outbreak last?
The duration of an interdigital corn outbreak varies depending on the cause, severity, and treatment. With proper care and addressing the underlying cause, soft corns can resolve within a few weeks. However, if the pressure and friction are not alleviated, the corn may persist or recur.
How is it diagnosed?
Diagnosis is typically made through a physical examination by a doctor or podiatrist. The characteristic appearance and location of the lesion between the toes are usually sufficient for diagnosis. No specific lab tests are usually required.
Timeline of Symptoms
The timeline of symptoms can vary, but generally follows this pattern:
Initial Stage: Mild discomfort or pressure between the toes.
Progression: Development of a small, soft, whitish or grayish area. Pain increases with pressure or wearing shoes.
Advanced Stage: The corn becomes more prominent, and the pain is more persistent. Inflammation and redness may develop. If left untreated, it may cause difficulty walking.
Important Considerations
Diabetes and Poor Circulation: Individuals with diabetes or poor circulation should exercise extreme caution when using over-the-counter corn removal products, as they can increase the risk of complications, such as infection or ulceration. Consult a podiatrist for safe and effective treatment.
Underlying Causes: Addressing the underlying cause of the corn, such as ill-fitting shoes or toe deformities, is crucial for preventing recurrence. Orthotics or other supportive devices may be recommended.
Professional Care: Persistent or painful corns should be evaluated and treated by a podiatrist. They can provide professional debridement (removal of the corn) and recommend appropriate treatment options.
