Okay someone please help me out here. There's something on the bottom of my daughters foot. About 2 months ago it wasn't this same size. It's gotten slightly bigger. I don't know if it's because her foot has gotten slightly bigger or what. I don't know what it is either, at first I thought it was a splinter or something sharp that got stuck, but now I don't know. I've been looking at it closely and it appears to be lines so it's not an intact piece of something but I'm not 100% sure of that either. I'm making an apt for her this week on Friday but till then someone ease my mind, am I being paranoid? *this is the best pic I could get. zoom in please*
