Sever’s Disease (Calcaneal Apophysitis)
A common cause of heel pain in active children
What’s Going On?
Sever’s Disease occurs when the growth plate at the back of the heel becomes irritated or inflamed.
It’s most common in active children aged 8–14, especially during growth spurts when bones grow faster than muscles and tendons can adapt.
Repetitive running and jumping place strain on the heel, leading to pain, swelling, and limping—often worse after sport or activity.
Common causes include:
- Rapid growth during puberty (tight calves or Achilles tendon)
- Sports that involve running, jumping, or sudden changes of direction
- Poor footwear or lack of heel cushioning
- Flat feet, high arches, or overpronation
