Key facts
Sever’s disease at a glance.
The essentials, in plain English — what Sever’s disease is, why it hurts during a growth spurt, and what the evidence says actually helps.
-
Definition
Sever’s disease is a traction apophysitis of the calcaneal growth plate — where the Achilles pulls on the growing heel bone.
-
Who it affects
Active children aged 8-14, typically during a growth spurt and often in football, gymnastics or running.
-
Bilateral in ~60%
Both heels are involved in around 60% of cases — a helpful clue that separates it from a stress injury.
-
Squeeze test
A firm side-to-side squeeze of the back of the heel reproduces the pain and is diagnostic in the right age group.
-
Imaging usually not required
The diagnosis is clinical — X-rays are reserved for red flags or an atypical presentation.
-
Self-limiting
Symptoms settle once the calcaneal growth plate fuses — usually within 6-12 months of onset.
Why this guide matters
Reassurance first, modification second.
Sever’s disease is self-limiting and does not cause long-term damage — this guide explains the condition clearly so families can manage it without fear.
-
It is self-limiting — that matters
Symptoms resolve once the calcaneal growth plate fuses. Naming the condition and explaining it is a big part of the treatment.
-
Do not stop sport altogether
Modify load rather than remove it — cross-training with swimming and cycling protects fitness and mental health.
-
Simple things work
Heel cups, calf stretching and cushioned trainers deliver most of the benefit — no fancy interventions required.
How the diagnosis is made
From painful heel to a clear plan.
The steps a UK GP will normally follow, in order — so you know what to expect and why.
Phase 1 · Recognising
Age, sport history and the squeeze test
Phase 2 · Confirming
Gait analysis and ruling out differentials
Phase 3 · Managing
Reassurance, load management, physio if needed
- 01
Recognising
Symptom + sport / age history
A child aged 8-14 with heel pain worse during and after sport — the story is usually enough to point at the diagnosis.
- 02
Recognising
Heel squeeze test
A firm side-to-side squeeze of the posterior calcaneus reproduces the pain — the single most useful bedside test.
- 03
Recognising
Calf and Achilles tightness
Assess ankle dorsiflexion and gastrocnemius length — tight calves drive the traction load on the growth plate.
- 04
Confirming
Gait analysis
Watch the child walk and run — look for early heel-off, overpronation and toe-walking patterns.
- 05
Confirming
Rule out plantar fasciitis / stress fracture
Consider differentials — plantar fasciitis is rare at this age and a calcaneal stress fracture needs exclusion in refractory cases.
- 06
Managing
Family reassurance
Explain the condition is self-limiting and does not cause long-term damage — a huge part of the treatment.
- 07
Managing
Paediatric physio input
For persistent cases — structured calf stretching, footwear review and a graded return-to-sport plan.
Typical timeline: 1–2 weeks from first appointment to a settled plan.
Symptoms
What Sever’s disease actually feels like.
The pattern is more telling than any single symptom — sport-related heel pain, a positive squeeze test and post-activity limping.
-
Heel pain worse with sport
Pain at the back of the heel that flares during and immediately after running or jumping activity.
-
Positive squeeze test
A firm side-to-side squeeze of the posterior heel reliably reproduces the child’s pain.
-
Sport-related aggravation
Symptoms track closely with training load — worse in season, better with rest.
-
Bilateral in 60%
Both heels are affected in around 60% of cases — a useful clue that supports the diagnosis.
-
Limping after sport
A mild post-activity limp or toe-walking pattern is common in the hours after training.
-
Tight calf / Achilles
Reduced ankle dorsiflexion and tight gastrocnemius are found on examination in most children.
-
Recurrent flares
Symptoms typically wax and wane over months in line with growth spurts and sport intensity.
-
Red flag
Night pain, fever or systemic symptoms — investigate for infection or malignancy rather than assuming Sever’s.
Treatment
How Sever’s disease is treated in the UK.
A staged approach — reassurance and load management first, with heel cups, stretching and physiotherapy layered in as needed.
-
Load management / relative rest
The single biggest lever — reduce running and jumping volume while symptoms settle, without stopping all activity.
-
Calf and hamstring stretching
Daily gastrocnemius, soleus and hamstring stretches — dull, unglamorous and consistently useful.
-
Heel cushion / gel heel cup
A simple silicone heel cup in both trainers absorbs impact and reduces traction at the growth plate.
-
Ice after sport
A 10-15 minute ice pack after training or games helps settle the post-activity flare.
-
Physiotherapy
A paediatric physio-led programme — stretching, calf strengthening and a graded return-to-sport plan.
-
Footwear review
Supportive, cushioned trainers with a small heel raise — avoid flat football boots on hard ground where possible.
-
Short-term activity modification
A temporary switch to lower-impact activity — swimming and cycling — during the worst flares.
-
Reassurance the condition is self-limiting
Parents and children need to hear this explicitly — the condition resolves once the growth plate fuses.

Red flags
When paediatric heel pain is not Sever’s.
Most paediatric heel pain is Sever’s and settles with load management. These are the situations where a different diagnosis needs to be considered.
-
Night pain (malignancy)
Pain that wakes the child from sleep is not typical of Sever’s and warrants urgent review to rule out bone tumour.
-
Fever + heel pain (osteomyelitis)
A hot, red, painful heel with fever needs same-day review — osteomyelitis must be excluded.
-
Unilateral persistent pain
Strictly one-sided pain that does not settle raises the index of suspicion for a stress fracture or other bony pathology.
-
Failed 3-month conservative therapy
Symptoms not settling after three months of good conservative care — reassess the diagnosis with paediatric orthopaedic input.
-
Bilateral flat foot with symptoms
Symptomatic pes planus in a child with heel pain — consider a biomechanical assessment and orthotic prescription.
-
Neurological symptoms
Numbness, tingling or weakness in the foot — investigate for tarsal coalition or a nerve entrapment, not Sever’s.
-
Calcaneal stress fracture differential
Focal bony tenderness with a positive hop test — image to exclude a calcaneal stress fracture.
-
Achilles avulsion (rare)
Sudden severe pain and inability to push off after a jump — a rare avulsion of the calcaneal apophysis needs urgent orthopaedic review.
-
Psychosocial impact of missed sport
Prolonged absence from sport has a real impact on children — flag low mood, anxiety or school avoidance for support.
Living with it
A temporary problem, but a very manageable one.
Four things that make the biggest difference day to day — stretching, supportive footwear, load modification and patient review.
A quiet reminder
Consistency beats intensity, every time.
Small, steady changes — kept up for months — do more than a heroic week that does not last.
- 01 Rehab
Stretch daily, gently
A few minutes of calf and hamstring stretches every day — kept up over months, not weeks — is the biggest single lever.
- 02 Footwear
Cushioned trainers, always
Supportive shoes with a heel cup indoors and out — avoid flat football boots on hard ground when symptoms are active.
- 03 Load
Modify, do not stop
Cut training volume rather than stop sport altogether — swimming and cycling keep fitness up during the worst flares.
- 04 Reviews
Reassess in weeks, not days
Give changes time — reassess at 6-12 weeks and involve paediatric physio if things have not settled.
Frequently asked
Everything we get asked about Sever’s disease.
Quick answers on load management, heel cups, stretching, return to sport and when to seek help.
-
What actually causes Sever’s disease?
It is a traction injury at the calcaneal growth plate, where the Achilles tendon pulls on the growing heel bone during a period of rapid growth. Tight calves, high sport volume and hard playing surfaces are the main drivers — not a single injury.
-
How long does it take to get better?
Most children settle over 6-12 months with load management, stretching and heel cups. Symptoms fully resolve once the calcaneal growth plate fuses, usually by around age 14-15.
-
Does my child need a scan?
Not usually. The diagnosis is clinical and based on age, sport history and a positive squeeze test. X-rays or MRI are reserved for red flags, unilateral persistent pain or an atypical presentation.
-
Should my child stop sport completely?
No — full rest is rarely needed and often counterproductive. The goal is to reduce training volume while symptoms flare, keep cross-training with swimming or cycling, and return to full sport gradually as pain settles.
-
Are heel cups worth buying?
Yes — a simple silicone or gel heel cup in both trainers is one of the easiest, cheapest and most effective early steps. They cushion impact and reduce traction at the growth plate.
-
What is the red flag I should not ignore?
Night pain that wakes the child from sleep, heel pain with fever, or strictly one-sided pain that does not settle — these need review to exclude infection, stress fracture or, rarely, a bone tumour.
