what can be a bump on my feet? and How they occur?

Question

what are the causes they develop because I just found it a week ago, it also feels like a bone

Answer 1

possibly a plantars wart which will become very painful if left untreated. these warts are spread by being barefoot in public places where others are often barefoot; showers like in a motel or campground etc. you can buy a remedy at any drug store if that is what it turns out to be. your md can diagnose it for you.

Answer 2

Maybe an bunion, or to be extra sexy, a ganglion cyst.
