Plantar warts often grow on the feet, what are plantar warts? Plantar warts are caused by the human papilloma virus and can be a skin growth on the foot. When plantar warts occur, it is now thought that many of them will go away on their own as the body recovers its resistance, but it is possible for them to recur in some people, and it is thought that preventing trauma is the key to preventing plantar warts from occurring. If plantar warts occur with more drastic symptoms, or even if there are a large number of warts, walking may be affected. Most plantar warts can be removed with oral and topical medications, as well as surgical treatment. Topical medications now include retinoids or 5-fluorouracil ointment applied to make plantar warts go away. Oral medications are also available, but nowadays the main oral medications are immunomodulators, such as zinc sulfate and retinoids, while plantar warts can be removed by freezing or laser if the symptoms are more severe and topical medications do not have a better effect. If the above methods are not effective, you can also use surgical treatment, but surgical treatment is easy to cause scarring.
