Common warts can often develop new growths around the area after being frozen. This situation is common in clinical settings because common warts are caused by HPV infection, a type of viral skin disease that tends to recur. Therefore, clinically, we recommend continuing treatment persistently after recurrence, whether by freezing, using lasers, or other methods, to fully resolve the issue. If treatment is delayed, the warts can increase in number. Commonly used physical treatments include freezing, electrocautery, scraping, lasers, etc., and are suitable when there are fewer lesions. Since there are currently no definitive effective anti-HPV medications, recurrence is common in clinical settings. At this time, we can use some immunomodulators, such as interferons, which have certain inhibitory effects. Simultaneously, traditional Chinese medicine methods such as clearing heat, detoxifying, dispelling wind, smoothing the liver, dispersing masses, and combined with external washing of Chinese medicine, can sometimes achieve better therapeutic effects.

Can common warts be pricked with a needle?

Common warts should not be punctured with a needle. The cause of common warts is a viral infection; they are caused by a type of human papillomavirus and manifest pathologically with hyperkeratosis, incomplete keratinization, and papillomatous proliferation of the epidermis. They do not form a cystic structure. Puncturing them with a needle will not only increase the risk of bacterial infection but also has no therapeutic effect. If you have common warts, the most appropriate action is to visit a hospital for treatment with options such as laser cauterization, cryotherapy with liquid nitrogen, or surgical removal of the lesions. This can completely remove the warts. If there are many warts or they keep recurring, it is also advisable to consult a doctor to see if medication should be combined with the treatment.

Does common warts spread by skin contact?

Common warts can be contagious through skin contact. Common warts, also known as verruca vulgaris, are caused by the human papillomavirus, abbreviated as HPV. Theoretically, common warts can be contagious through close contact, but transmission is not guaranteed upon skin contact and depends on each individual's resistance to the virus. When affected by common warts, it's important to enhance the cleanliness of the affected skin area, and also to disinfect clothing and the surrounding environment. Treatment can be supported by using immunomodulators among other symptomatic therapies. The primary treatment for common warts is physical removal methods, such as liquid nitrogen freezing or carbon dioxide laser treatments to remove the warts, and topical application of interferon gel can also be used.

Can common warts be cut with scissors?

Common warts should not be cut with scissors. Common warts are a type of viral skin infection caused by the human papillomavirus resulting in benign growths. Using scissors to cut them can easily lead to further infections, so it is not recommended to use scissors to remove common warts. If you have common warts, you can visit the dermatology department of a standard hospital. If the warts are small, you can apply creams containing retinoic acid or imiquimod cream. If topical medications are not effective, treatments like liquid nitrogen freezing or carbon dioxide laser treatment can be employed. The occurrence of common warts is also somewhat related to a decrease in the body's immune function, so it is important to exercise regularly to boost the immune system and avoid staying up late.

What harm does not treating common warts do to the body?

Common warts are caused by papillomavirus infections. This disease is contagious and recurrent, with the most common sites of occurrence being the soles of the feet or the palms and fingers. It is important to treat this disease in a standardized and timely manner, otherwise, it may grow increasingly numerous. Warts that develop on the soles can multiply over time, causing pain while walking. If they continue to increase, some may become inflamed, infected, suppurate, or exude fluid. When warts increase in number on the hands, they can affect work, as contact with hard materials can cause pain. Therefore, it is crucial to seek standardized treatment upon discovering this disease. Although it does not significantly affect an individual's health, it can impact one’s daily life and work.

Will common warts grow back after being removed?

Common warts, even when picked off, are very likely to regrow, as they are benign growths caused by an infection of the skin and mucous membrane with the Human Papillomavirus, or HPV. Due to their viral nature, they tend to recur easily. Common warts, also known as verruca vulgaris or plantar warts, are typically caused by HPV type 2 and mainly occur between the ages of 5 and 20. They can appear on any part of the body due to autoinoculation and are most commonly found on the hands and feet. These areas are susceptible due to frequent injuries or prolonged exposure to water, which are common triggering factors. After a wart is removed, the surrounding areas might already be infected, potentially leading to new warts appearing over time.
