Corns are small, thickened areas of skin that typically develop on the tops and sides of the toes or on the balls of the feet due to friction or pressure. The primary symptom of corns is localized pain and tenderness, especially when pressure is applied, such as when wearing shoes, walking, or standing for prolonged periods. Corns can be hard or soft; hard corns are firm and dry, often forming on the top of toes or in areas of high pressure, while soft corns are moist and rubbery, usually found between the toes where moisture from sweating aggravates them.

In addition to pain, corns may appear as a raised, hardened bump surrounded by inflamed skin. The affected area might be rough, yellowish, and thickened, with a central core that can press into the deeper layers of skin, causing significant discomfort or irritation. Over time, if left untreated, corns can become increasingly painful, making it difficult to walk or wear shoes comfortably. In severe cases, corns can lead to blisters or infections if the skin breaks down. Early diagnosis and treatment by a healthcare professional are essential to manage symptoms effectively, prevent complications, and avoid recurrence.
