For small warts , several medications(like podophyllum resin, Podofilox (Condylox), Trichloroacetic and bichloroacetic acids, Imiquimod 5% cream and interferons) are available, which can be applied directly to the surface of the warts. Other treatment options include electrical cautery, surgical removal, Carbon dioxide laser treatment and electrodesiccation.
In my opinion you should talk to a cosmetologist/dermatologist about this and get these warts evaluated. I hope it helps. Take care and regards.
