I did that too about 8 years ago. Jumped over a fence in the yard and there was some old wood debris under the leaves left by the previous owner. BIG nail through my hiking boot, deep into the ball of my right foot. Could not pull it out on my own. Sat in the yard and hollered for my boys. My oldest brought me a big framing hammer. The way it was angled, I tried knocking it off but after three tries that didn't work anymore. I had to pry it off. I might have hollered and inadvertently taught my boys a curse word. Limped to truck and straight to Dr. office. They cleaned it, gave me a shot, tetanus shot, put me on antibiotics...couldn't hardly walk for a couple days.

Don't play..go to a doctor.
