A corn is a small, thickened area of hardened skin that forms in response to friction and pressure. Most commonly, corns develop on the feet at pressure points—such as the tops of the toes or between them—where skin rubs against shoes or other toes.

Why Corn Treatment Is Necessary

Corns do not go away on their own. They are typically a sign of an underlying structural issue in the foot, such as misalignment or ill-fitting footwear. Without addressing the source of friction, corns can grow thicker, become more painful, and potentially lead to complications.

Over time, corns can press into the skin and irritate underlying nerves, causing significant discomfort. In severe cases, the body may treat the corn as a foreign object, leading to ulcer formation. This is especially dangerous for individuals with diabetes or poor circulation, as ulcers can lead to serious infections.

How Corns Are Treated

While mild corns can sometimes be managed at home, persistent or painful corns should be treated by a medical professional. Treatment typically begins by identifying and eliminating the source of pressure—often by changing footwear or using padding to reduce friction.

In-office removal is quick and straightforward. A podiatrist uses a small, sterile blade to carefully trim away the thickened skin. If foot deformities, such as hammertoes or bunions, are contributing to the problem, surgical correction may be necessary to prevent recurrence.

Individuals with diabetes, peripheral neuropathy, or poor circulation should avoid self-treatment, as they face a higher risk of complications from even minor foot injuries. Seeking professional care is essential for safe and effective treatment.
