Why active kids can play but limp afterwards
It is very common for children between the ages of 10 and 15 years to experience pain in their heels and knees, particularly during periods of rapid growth.
Parents are often confused by this condition. A child may run, sprint and complete a full football or netball match with no obvious issue but within minutes of stopping, they begin to limp and complain of significant pain.
This can sometimes lead others to doubt the severity of the problem. However, this pattern is very typical and has a clear medical explanation.
What is happening during growth?
Children’s bones grow from areas called growth plates, located at the ends of bones. During growth spurts, these plates become highly active.
A simple way to understand this is to imagine a volcano that is active but not erupting. The growth plate is constantly producing new bone, but during a surge of growth hormone, this activity increases rapidly, making the area sensitive, inflamed and vulnerable to stress.
Why the heel and knee are affected
The back of the heel
At the back of the heel sits a growth plate in the heel bone.
The Achilles tendon attaches here. When a child runs or pushes up onto their toes, the calf muscles contract. This creates a strong pulling force on the growth plate.
This condition is known as Sever’s disease.
The front of the knee
At the front of the knee, just below the kneecap, there is another active growth plate.
The quadriceps muscle pulls via the patellar tendon. During running and jumping, this repeatedly stresses the growth plate, especially when lifting the toes or accelerating.
This condition is called Osgood Schlatter disease.
Why the pain appears after activity
One of the most confusing features is that children can often play sport without pain but suffer immediately afterwards.
This happens because during activity, the body is warm and flexible. Blood flow increases and temporarily masks discomfort. Once activity stops, inflammation rises rapidly and the irritated growth plates become painful very quickly.
This is why children may begin limping within minutes of finishing sport.
Why both sides are often affected
Unlike injuries, this condition frequently affects both heels and both knees.
This is because growth and muscle forces occur symmetrically during development.
The role of foot alignment
Children who are growing quickly often have softer ligaments and increased joint flexibility. This can cause the ankles to roll inward and flatten the arches of the foot.
This can increase strain on the heel and knee and make symptoms worse.
A professional assessment can identify whether foot alignment is contributing to the problem.
How to manage the pain
Immediate relief
Apply cold compression within minutes after activity. Ten minutes is usually effective and helps reduce inflammation quickly.
Footwear support
Use cushioned sole shoes or slightly raised heel footwear. Heel lifts or orthotics inside sports shoes or football boots can also help.
These reduce the pulling force on growth plates.
Activity modification
In more severe cases, rest from sport may be required for two to six weeks. This allows the growth plate inflammation to settle.
Continuing through severe pain can lead to excess bone growth and prominent bumps at the heel or knee, causing long term discomfort.
When to seek professional help
A podiatry assessment is recommended if pain persists or worsens, if the child begins limping regularly, if there is visible swelling at the heel or knee, or if performance in sport is affected.
A full foot, ankle and leg assessment can help your child continue activity safely, often with simple and effective interventions.
Final thoughts
Heel and knee pain during growth is common, real and treatable.
Understanding the condition is key.
Just because a child can play through it does not mean there is no problem. With the right support, children can continue to stay active, develop safely and avoid long term issues.
