And then what? Common warts usually occur on fingers, back of hands, nail edges and feet. The common wart is a single wart when it first attacks, and it can be inoculated and enlarged by itself. Most of them have no discomfort symptoms and have chronic attacks. There are many treatments for verruca vulgaris, and laser is just one of them, specifically CO2 laser. In addition, sharp spoon curettage, liquid nitrogen freezing and surgical resection can also be used. In addition, external use of crow's feet or external use of 5- fluoropyrimidine ointment or verruca vulgaris is also effective. Although laser can remove verruca vulgaris, it still needs some auxiliary treatment. For example, for intractable verruca vulgaris, while laser can eliminate verruca vulgaris, some treatments to improve immunity are needed, and liquid nitrogen cryotherapy can be carried out if necessary. Verruca vulgaris is not difficult to treat, but you need to go to a regular plastic surgery hospital to find a skin expert, so as to ensure the therapeutic effect.
