Suggest Treatment For Leg Pain After An Injury

I am in high school and I am currently playing softball. Recently I have been repeatedly getting hit on the lower half of my left leg and I have a ton of bruises covering my leg. Today at practice I was running for a ball in the outfield and tripped. When I hit the ground my leg hit first and I immediately felt intense pain. I am used to playing through injuries but this was definitely not something i wanted to play with. I can"t put any pressure on my leg or even move it without it hurting. My coaches kept telling me to shake it off and made me go back out and play after I asked to take a break numerous times. Its is about an hour and a half after that happened and my leg still feels worse now from having to practice on it. I think I may have bruised the bone but I am not sure. Could you help me? Thank you
