Corns are primarily caused by the prolonged and repeated irritation from foreign objects entering the skin, and they are also somewhat related to one’s walking habits or footwear. Once formed, they can be painful, and in severe cases, may lead to pus-filled infections. Typically, corns can be effectively treated with common corn plasters.

If the treatment with corn plasters proves ineffective, one can seek cryotherapy with liquid nitrogen at a dermatology department in a standard hospital. In more severe cases, surgical removal may be necessary. Generally, corns can be completely cured using these methods. It is advisable to wear loose-fitting shoes regularly, avoid tight shoes that compress the feet, and not walk barefoot to prevent foreign objects from re-entering the skin and causing a recurrence of the condition.
