I ran 9miles today and i'm to sore to move. How can i help my muscles heal? i haven't run a mile in 9months.

I'm not a runner, I'm an equestrian. I don't usually run because i had a severe knee injury a couple years ago. I just decided to run 9 miles because i wanted to. I hurt so bad and even if i'm not moving i hurt. How can i help my muscles heal quickly?????
