i have a small boil that is painless and harmless on my scrotum , but it is in the way which makes it uncomfortable whenever i press it a string of white puss like substance comes out, but not liquid, sort of solid. after removing alot of this , a tiny amount of blood comes out and then it reduces greatly in size.. and then im fine. but after a few weeks it fills up to that size again. how do i get it removed? thank you.
