Children are at greatest risk for Sever disease when they have reached the early part of a growth spurt in early puberty. For girls, this is around ages 8 to 10. For boys, it happens somewhere between the ages of 10 to 12. By the age of 15, the back of the heel has stopped growing in most children. Sever disease then becomes rare.
Any running or jumping activities can raise the odds that a child will get Sever disease. Soccer and gymnastics are common sports that tend to put children at risk.
