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.
