Plantar warts do not grow on the arms, those that do are common warts, which can be destroyed by medication as well as physically to regulate localized skin growth. Common warts are benign skin growths caused by human papillomavirus infection. Some warts can go away on their own, but when there is significant pain that affects aesthetics, they can be treated with medication such as salicylic acid, retinoic acid, imiquimod cream and other medications applied to the affected area, as well as physical therapy such as freezing, electrocautery, and lasers. Daily life should pay attention to the regularity of life, strengthen physical exercise, improve immunity, avoid friction and impact on the skin lesions to prevent bleeding or infection. The treatment should be carried out under the operation of professional doctors, and the medication should be in accordance with the doctor’s prescription.
