I Have a Weird Bone Sticking out of the Side of my Foot, What Do I Do? (photo)

http://i50.tinypic.com/20psxfd.jpg it's not a bunion at the top of my foot, it's not fatty tissue, it's bone. both of my feet have bones on the corner of the side of my foot but 1 is more prominent and bigger than the other. The 1 on my right foot is huge. it doesn't necessarily hurt me, but it looks ugly& feels funny when it touches my shoe. Do I try to push it back in with a band or a cast?People are scaring me saying that its arthiritis :-( but my feet don't really hurt it's just concerning
