What have I done to my foot?

Hi As you say your foot is not bruised,but is swelling,this will come later as the lump means you have damaged the foot with this ornament,you may have cracked a bone in your foot,bandage your foot to keep it as restricted as possible,try not to put much pressure on it ,i know you have to walk,but with the weekend coming up rest it as much as possible.There is no repair to a cracked bone in the foot unless it is drastically damaged.Time will tell,you have to be very patience and take a pain killer for the pain.Good luck John
