Common warts may subside naturally without treatment, so they sometimes heal on their own without treatment. However, when they are painful, noticeably aesthetic, or spread over a large area, treatment is necessary. Common warts are caused by human papillomavirus infection and are benign growths of the skin. They are mainly hard papules with a rough surface to touch and can occur on any part of the body, usually on the hands, and can recur. When there is a break in the skin or mucous membrane, HPV may invade through the break and infect the epidermal cells of the skin, causing common warts. In most cases, the warts will heal on their own without treatment. In some cases, physical therapy such as freezing, electrocautery, or laser can be used to remove the warts. The actual warts will be the most important thing that you can do for you.
