My foot hurts!

So the side of my foot was rather sore after going to the beach on Saturday, but I thought nothing of it. Today however, I was at work all day on my feet, and my foot was rubbing against my shoe all day. Finally I decided to see why it was hurting so much. It turned out that I had a piece of glass, crystal, crystallized venom, or possibly even a diamond embedded in the side of my foot! It feels much better now.
