First of all it is necessary to confirm whether it is a wart or some benign skin growth. Mostly warts go away on their own but sometimes they may need treatment. For small warts that affect only the skin, 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 this wart evaluated.
I hope it helps. Take care and regards.
