Pediatric heel pain, called Sever's disease, is caused by overuse. As the bones grow in a child's foot, the heel bone's growth plate at the bottom and back of the heel may be stressed.  The Achilles tendon, or heel cord, inserts on the back of the heel and when it pulls on the back of the heel and growth plate your child feels pain.   Certain sports involving jumping such as basketball or gymnastics will mean stressing that tendon more. Other sports such as soccer, baseball or track that involve your child wearing cleats, which have minimal heel and arch support, may also stress the heel.  For any pediatric heel pain, the most important thing you can do is have your child examined and start a treatment plan.  That way, he or she can get back to the sport that they love playing, and be able to play pain-free.
