rolled foot

I was playing basketball and I rolled my left foot under, towards the outside, I had a sharp pain for like five minutes then I finshed the game, after the game I went swimming for an hour, it still hurt but I could walk, I drove home and when I got out of the car it was tight but I could still walk, I took a nap and when I woke up that was it the pain was intense, I can not walk and no matter where I place my foot It kills me? what can I do I don’t have insurance and I really have had bad experiences going to the V.A. hospital.
