Rope burn

So I was lead climbing, which is where you climb and clip in the rope as you go, and my leg got tangled in the rope right when I was trying to clip in so I tried to untangle it, but my foot slipped and I fell, in lead climbing you fall amazing distances, and my leg was still tangle so I ended upside down and with a huge rope burn on my leg, now I don't have a lot of skin left on my leg.
