Why does my ankle hurt after running?

I do sprints for track and after jogging a half mile warm up, they dont really hurt. After the first sprint of any distance it begins to hurt, but not unbearable pain. The next sprint they hurt a decent amount, and after the third i wanna chop off my legs it hurts so bad. The pain is right between the ankle bone and achilles tendon but not on the tendon. It also hurts to touch there when it hurts. The weird thing is that it doesnt hurt while im running but its almost unbearable after a few seconds of stoping the sprint. On the days it hurts a lot it can take 30 minutes to an hour to stop hurting and even short intervals of running faster than joggin theybegin to hurt, like shhoting hoops and taking a quick run to get the ball before it bounces away. The only thing the coaches told me to do was ice it and ive been doing that for the past week. What is matter with my ankles?!!!
