Most common warts go away without treatment, though it may take a year or two and new ones may develop nearby. Some people choose to have their warts treated by a doctor because home treatment isn’t working and the warts are bothersome, spreading or are a cosmetic concern. The goals of treatment are to destroy the wart, stimulate an immune system response to fight the virus, or both. Treatment may take weeks or months. Getting warts sorted out earlier will result in a less painful removal/ overall experience.
