It looks like recurrence of warts. You can go for
other treatment options of warts
this 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.
I hope it helps.
