There is no such thing as the root of corns, but it can be improved by general treatment, medication, physical therapy and surgery. 1. General treatment: If corns appear on the skin, patients should avoid localized skin being squeezed or rubbed. If it occurs on the feet, soft, loose and breathable shoes and socks should be chosen as much as possible to help relieve the symptoms of the disease. 2. Medication: Patients should soak the affected area in hot water before using medication, and then use salicylic acid or urea ointment externally as prescribed by the doctor, which helps to soften and dissolve the keratin. However, it should be used several times until the corns fall off. 3. Physical therapy: If the effect of drug treatment is not good or the condition is more serious, you can take physical therapy, such as electrocautery, laser and freezing, etc., which can remove the corns. 4. Surgery: For patients with more serious conditions, corns can be removed by exfoliation, where an incision is made around the corneal plug and the corns are dug out, and the affected area is sterilized and bandaged, which will help the disease to recover. There are more ways to improve corns, it is recommended that patients go to regular hospitals and cooperate with doctors for standardized treatment.
