Corns are a common foot condition where the skin becomes thickened and hard in response to friction or pressure. They usually develop on the feet, especially on the toes and soles, and can cause pain, discomfort, and even difficulty walking.
Corns are caused by repetitive rubbing or pressure on the skin, often due to ill-fitting shoes or abnormal foot structures such as hammertoes or bunions. They can also develop from activities that put pressure on the feet, such as running or dancing.
There are two types of corns: hard corns and soft corns. Hard corns are small, raised, and have a hard centre surrounded by thick, rough skin. They usually develop on the tops and tips of the toes, and are often caused by tight-fitting shoes or toe deformities. Soft corns are white and rubbery, and develop in between the toes, often due to excess moisture.
Corns can often be treated at home by soaking the affected area in warm water, using a pumice stone to gently rub away the thickened skin, and applying moisturiser to keep the area soft. However, if the corn is causing severe pain or discomfort, a podiatrist may need to remove it using special tools. To prevent corns from developing, it is important to wear properly fitting shoes, and to use cushioned insoles or pads to reduce pressure on the feet.
