I got a horrible cramp in football camp?

dude, first I caught this one in my left thigh while we were doing stretches. We dont really stretch by the way, we sorta warm up. anywho, i caught a cramp in my right thigh and ive been trying to stretch it out. its been there for about two days now man. and today we ran our forty yard dashes and I got a bad time because of the cramp i was running on. by the time i finished i had a cramp in my left thigh as well, which wont go away either. tomorrow is the last day for a week and i really want to show off so i can make varsity. JV is embarrasing at my school for a junior. how do i get it out?!?
