Warts are caused by a virus and are small lumps that feel rough and firm. They are contagious and can spread through skin contact or from contaminated surfaces.
Warts are not harmful and most people get one at some point of their lives. They can vary in size from a tiny pinhead to about a pea size. They can disappear on their own or could stay forever. Some people find warts embarrassing, Itchy or painful and would like them removed.
