Growing pains aren’t simply “part of growing” — new research shows they’re a predictable response to rapid growth, changing biomechanics, and increased sport demands. A major study across English Premier League academies mapped when and where pain shows up in kids, revealing patterns every parent should know. Younger kids often experience heel and foot pain, while knees become the main issue from age 12, and hips/groin take over in the mid-teen years. Understanding these patterns helps parents recognise when to rest, when to adjust sport load, and when to seek help. With smart strengthening, proper load management, and early intervention, kids can stay active, confident, and pain-free as they grow.
