Serious foot pains what did I do and what can I do now?

I was playing kickball with my little brothers and while running I steped on a rock probobly about the size of a potato sticking half out of the ground in the shape of a lopsided pyramid. I noticed painat the time but did not stop and think about it instead I continued on playing. Later in the game I noticed more severe pain and decided to quit. After goig to bed and waking up the next morning It hurt more and I could not walk on it or apply any pressure on it whatsoever

a couple notes

-I am talking about the pinky toe on my left foot

-there is minor swelling just above the pinky toe

-I can wiggle all toes slightly
