Corns on the hands can be treated with topical medications, physical therapy, and surgery. Corns are due to localized excessive friction, caused by excessive proliferation of the stratum corneum, which may lead to symptoms of localized pain. 1. Topical medication: you can use salicylic acid ointment, corns cream and other drugs for local treatment. 2. Physical therapy: corns can be removed by freezing, laser and other methods. 3. Surgery: If the symptoms do not improve after taking the above measures, the corns can be removed through surgery. If you have long corns on your hands, you should reduce the local friction and extrusion, go to the regular hospital for examination in time, and use the medication under the guidance of a professional doctor.
