The pain of running

I was running on the treadmill this evening.  I am recovering from a stress fracture and starting the third week of a seven week recovery/return to running program.  Today I experienced some pain in my left foot and calf.  I did some leg squats and calf extensions yesterday at the gym.  While working my calves I did experience a cramp in my calf.  I'm hoping with some rest I'll be back for my normal recovery run program.
