Quick answer: Sever’s disease is the most common cause of heel pain in active children aged 8–14, caused by growth plate inflammation where the Achilles tendon attaches. It is self-limiting but treatable with heel cups, stretching, and activity modification to keep your child active and pain-free.

| Treatment | Condition | Evidence | Duration | Notes |
|---|---|---|---|---|
| Heel Cup / Cushioned Insert | Sever disease (first-line) | Level II — shortens symptomatic period | Throughout symptom phase; wear daily | Off-the-shelf Silipos or Tuli’s heel cup; 60–70% symptom relief |
| Achilles Stretching (3x daily) | Sever disease; insertional Achilles | Level II | Indefinite; throughout growth | Gastrocnemius and soleus stretch; runner’s stretch; stair drop stretch |

Quick Answer:
Quick Answer: The most common cause of heel pain in active children ages 8–14 is Sever’s disease (calcaneal apophysitis) — inflammation at the growth plate where the Achilles tendon attaches to the heel bone. It is not dangerous and does not cause permanent damage, but it causes significant activity-limiting pain during growth spurts. Treatment with heel cups, activity modification, stretching, and occasionally orthotics resolves the condition as the growth plate closes, typically by ages 14–16.
When an active child starts limping after soccer practice or complains of heel pain that gets worse during sports, Sever’s disease (calcaneal apophysitis) is the most likely diagnosis. It is the most common cause of heel pain in children ages 8–14, occurring during growth spurts when the Achilles tendon temporarily fails to keep pace with the growing heel bone. At Balance Foot & Ankle PLLC, Dr. Tom Biernacki provides accurate diagnosis and effective treatment for pediatric heel pain — getting young athletes back to their sport safely.
What Is Sever’s Disease?
The calcaneal apophysis is the growth plate at the posterior heel where the Achilles tendon inserts. During rapid bone growth, the apophysis is vulnerable to repetitive tensile stress from the Achilles tendon — causing microtrauma, inflammation, and pain. It is called an “apophysitis” — inflammation of the growth center — not a true injury or fracture. Risk factors: male sex (more common but females are also affected), high activity level, sports on hard surfaces (soccer, basketball, gymnastics), flat feet, tight Achilles tendon, and rapid growth spurts. X-ray shows fragmentation of the apophysis — a normal radiographic variant, not pathological.
Treatment Protocol
Heel Cups / Heel Lifts: Silicone heel cups reduce tensile stress on the apophysis by elevating the heel and absorbing ground impact. First-line intervention — significant symptom relief in most children within 1–2 weeks. Achilles/Calf Stretching: Gastrocnemius and soleus stretching reduces tensile load on the apophysis. A structured 3x daily stretching program is prescribed. Activity Modification: Avoid complete rest — maintain conditioning with low-impact activity (swimming, cycling). Return to sport when pain-free or near pain-free. Custom Orthotics: Indicated for children with associated flatfoot deformity or who fail heel cup management — orthotic controls hindfoot biomechanics and reduces apophyseal stress. Ice and Anti-inflammatories: Ibuprofen or naproxen for 7–10 days during acute flares. Ice post-activity 15 minutes.
When Will It Go Away?
Sever’s disease resolves completely when the apophysis fuses to the calcaneus — typically by ages 14–16 in girls and 15–17 in boys. The condition may recur with each growth spurt until fusion. There are no long-term consequences from Sever’s disease — it does not cause arthritis or permanent damage. The goal of treatment is managing symptoms during growth rather than curing the condition.

✅ Pros / Benefits
- Sever’s disease resolves completely with skeletal maturity — reassurance is as important as treatment
- Heel cups provide rapid symptom relief — most children improve within 1–2 weeks
- Custom orthotics address underlying flatfoot biomechanics for recurrent cases
- Active treatment approach — children maintain conditioning during recovery
❌ Cons / Risks
- Sever’s disease may recur with each growth spurt until apophysis fuses at ages 14–17
- Activity restriction is frustrating for competitive young athletes
- Custom orthotics require replacement as the foot grows
Dr. Tom Biernacki’s Recommendation
Sever’s disease is one of those diagnoses parents are relieved to hear — because it means their child’s heel pain has a clear cause, a clear treatment, and a guaranteed end date. The apophysis closes, the condition disappears, no long-term damage. Our job is to manage symptoms well enough that kids can stay active and keep developing through their sport while they grow through it.

Frequently Asked Questions
How do I know if my child has Sever’s disease?
Signs: heel pain in an active child between ages 8–14, pain at the back and bottom of the heel (not the arch), worsening with sports and improving with rest, pain with squeezing the sides of the heel, no swelling or bruising. X-ray shows apophyseal fragmentation (normal variant). The diagnosis is clinical — Dr. Biernacki evaluates your child’s specific presentation to confirm and rule out other causes.
Can my child keep playing sports with Sever’s disease?
Yes, in most cases. Complete rest is rarely necessary or advisable. Activity modification — reducing training volume and intensity during flares, using heel cups consistently, performing daily stretching — allows most children to continue participating in sports with acceptable symptom control. Complete rest often worsens deconditioning without speeding recovery.
Is Sever’s disease serious?
No — Sever’s disease does not cause any permanent damage to the heel bone or growth plate. It is painful and activity-limiting but completely benign. It resolves without exception when the apophysis fuses at skeletal maturity. Early, aggressive cortisone injection is not appropriate — this is a self-limiting condition managed conservatively.
At what age does Sever’s disease stop?
Sever’s disease resolves permanently when the calcaneal apophysis fuses to the heel bone — typically ages 14–16 in girls and 15–17 in boys. Once fused, recurrence is impossible. Until fusion occurs, flares may recur with each growth spurt. After the apophysis closes, these children are at normal (non-elevated) risk for Achilles tendinopathy as adults.

When should I see a doctor?
See a podiatrist if pain persists past 2 weeks, prevents normal activity, or is accompanied by red-flag symptoms (warmth, swelling, numbness, inability to bear weight).
Can I treat this at home?
Mild cases respond to RICE protocol (rest, ice, compression, elevation), supportive shoes, and OTC anti-inflammatories. Persistent symptoms need professional evaluation.
How long does it take to heal?
Most soft tissue injuries resolve in 2-6 weeks with appropriate care. Bone injuries take 6-12 weeks. Chronic conditions need longer-term management.
