Hi. I Took A Line Drive From A Softball On

Hi. I took a line drive from a softball on the inside of my left leg, below my knee sort of on the side of my shin and on my calf muscle. This was 3 days ago. Ive had to work on my feet the last couple of days and especially after 4 hours the pain gets much worse. And weirdly, I get the most pain on the front of my shin, lower than the impact are. Its sharp and burning, especially when I step on it, and that area feels a bit numb if I touch it. Weirder still, at the end of my shift, my whole leg was swollen below the knee, and tonight there was a dark purple discoloration all below the inside of my ankle on my foot. Thanks.
