Corns can be treated by general treatment, medication, physical therapy or surgery. Corns are localized hyperplastic damages caused by long-term friction, extrusion and other stimuli that lead to local skin thickening. 1. General treatment: If the corns are relatively small and there is no obvious pressure or pain, you can observe them for a while, and the corns may subside on their own by replacing them with suitable shoes and socks, so be careful not to wear small, breathable shoes and socks. 2. Medication: For relatively small corns, you can use topical medication, such as corns cream, salicylic acid ointment, etc., to soften the thickened tissue of the corns and make them fall off, so as to get rid of the corns. 3. Physical or surgical treatment: If the corns are large and painful, you can use cryotherapy, laser treatment, electrocautery treatment to remove them; if the above treatment is not effective or the lesions are large, you can choose surgical treatment, and after the operation, you should keep the area dry and clean to prevent infection. It is recommended that patients with corns go to the hospital in a timely manner, standardized treatment under the guidance of the doctor, do not self-medication or the use of prescription treatment, resulting in serious adverse consequences.
