Plantar warts on the feet can be treated by medication, surgery, physical therapy and other treatments, which need to be analyzed specifically. 1. Drug treatment: mainly take topical drugs, local injection drugs, etc. Topical drugs include salicylic acid, vita-acid ointment, zanthoxylin, etc.; local injection drugs include paxillin, bleomycin, etc. 2. Surgery: If other treatments fail, surgery can be used to remove the plantar warts, but it is easy to cause scarring and easy to recur. 3. Physical therapy: If the plantar warts are small, you can make them necrotic and fall off through physical therapy, such as liquid nitrogen freezing, electrocautery, laser, microwave and other treatment methods. The above treatments need to be used under the guidance of a doctor, and it is recommended that the patient consult a doctor in a timely manner and choose the appropriate treatment method under the guidance of a professional doctor.
