its been a month since I had my right calf injured, I only thought its a simple muscle cramps until I had a hard time using stairs. I apply Kinesio tape for days and still continue to play, I didnt see a doctor,
then after 3 weeks with less pain from the muscle I went to a gym to enhance or develop the muscle that was weaken by the injury.
Now, i can move it again normally in and out of court.
before stretching prior to playing, its better to do some light warm up exercise. A cold/static stretch could also be more damaging to your muscle and game play.
Active stretches that mimic the movement of your intended activity, like some deep knee lunges, movements that the pros do before a match..
