What are the bony protrusions on sides of my son's feet?
I never noticed until yesterday, my son was laying on the couch and had his legs on my lap. I grabbed one of his feet and he say "oouch". So after looking at what he was complaining about I noticed along the outer side of his foot if I run my hand up it, a bony protrusion is there. It comes out on the side of his foot about mid way up the side and then goes back in when you move up toward the toes. It's that way on both feet. What the heck could that be? I've never noticed it before and he never pointed it out to me until I touched it yesterday. Is it normal on a 13 year old's growing feet?
