Sever's Disease Treatment: Get Kids Back to Sport | DPM

Quick answer: Treatment for sever disease treatment follows a stepwise approach: 1) conservative care first (rest, ice, supportive footwear, OTC anti-inflammatories), 2) physical therapy and targeted exercises, 3) in-office treatments (injections, custom orthotics) if conservative fails at 4-6 weeks, 4) surgery for refractory cases. Most patients resolve at step 1 or 2. Call (810) 206-1402.

What Is Sever’s Disease?

Sever’s disease (calcaneal apophysitis) is the most common cause of heel pain in children and adolescents aged 8–14. It is not a true disease but rather an overuse injury affecting the growth plate (apophysis) at the back of the heel bone, where the Achilles tendon inserts. During growth spurts, the heel bone grows faster than the surrounding soft tissues, placing the Achilles tendon and plantar fascia under increased tension. Repetitive traction forces at the growth plate from activity—running, jumping, cleated sports—cause microtrauma and inflammation at the apophysis, producing pain. Sever’s disease is self-limiting and always resolves when the growth plate closes (typically by age 14–16), but the pain can be significant and activity-limiting during the growing years.

Symptoms and Diagnosis

The classic presentation is bilateral (or unilateral) heel pain in an active child aged 8–14, worst at the back of the heel, worsening with activity and improving with rest. Pain is specifically at the posterior-inferior heel—at the Achilles insertion—rather than the plantar surface under the heel (which would suggest plantar fasciitis, rare in children). The squeeze test (squeezing the sides of the heel) reproduces the pain at the apophysis and is the most reliable clinical diagnostic sign. Walking on tiptoes may reduce pain (shortening the Achilles reduces tension). Diagnosis is clinical—X-rays are not required for a classic presentation but may be obtained to rule out fracture; X-rays will show sclerosis and fragmentation of the calcaneal apophysis, which is normal in this age group and not diagnostic by itself.

Treatment: What Works

The most effective treatments are those that reduce tension on the Achilles tendon at the apophysis. Heel lifts (gel or foam inserts that elevate the heel, reducing Achilles stretch) provide immediate pain relief and are the single most effective first-line treatment. Calf stretching performed consistently 2–3 times daily addresses the tight Achilles that transmits excessive force to the growth plate. Activity modification—reducing running and jumping volume during acute flares—allows inflammation to settle, but complete rest is rarely required or beneficial. Ice application for 10–15 minutes after activity reduces acute inflammation. Supportive footwear with adequate heel cushioning is important; cleated athletic shoes with rigid soles and minimal heel lift are a common contributor to Sever’s pain in soccer and baseball players. In persistent or severe cases, a short course in a walking boot (2–4 weeks) unloads the apophysis and allows resolution. NSAIDs provide short-term pain relief. The prognosis is excellent—all cases resolve permanently with skeletal maturity.

Frequently Asked Questions

How long does plantar fasciitis take to heal?

Most plantar fasciitis cases resolve within 6–12 months with consistent treatment. In our clinic, patients who begin care within the first 8 weeks see 80% improvement by month 3. Chronic cases — pain lasting over a year — typically require PRP injections or surgical intervention, but fewer than 5% of our patients reach that point. Starting treatment early is the single biggest factor in shortening recovery.

Why is plantar fasciitis pain worst in the morning?

Overnight, the plantar fascia contracts in a shortened position. Your first steps stretch it abruptly, causing micro-tears at the heel attachment and sharp pain. This ‘first-step pain’ that eases after 10–15 minutes is the hallmark diagnostic sign. If your pain worsens throughout the day rather than improving, a different diagnosis — stress fracture, fat pad atrophy, or nerve entrapment — should be explored.

Can I walk or run with plantar fasciitis?

You can often continue with modifications, especially in early-stage cases. Reduce mileage by 30–50%, avoid hills and speed work, and run on softer surfaces. Add aggressive calf stretching before and after. If pain exceeds 4/10 during activity, stop — pushing through moderate-to-severe pain causes scar tissue formation that can double your recovery time. We reassess runners every 3 weeks to adjust the plan.

Does plantar fasciitis require surgery?

Surgery is required in fewer than 5% of cases. We exhaust conservative options first: custom orthotics, physical therapy, night splints, corticosteroid injections, and shockwave therapy. If those fail after 6–12 months of consistent treatment, plantar fascia release or PRP is considered. In our practice, patients who follow a structured protocol almost never reach surgery.

What shoes help plantar fasciitis the most?

The three features that matter most: firm arch support (not soft cushioning — soft foam collapses under load), a slight heel elevation of 8–12mm to reduce fascia tension, and a wide, deep toe box. Motion-control and stability shoes outperform neutral cushioned shoes for most plantar fasciitis patients. Avoid flat shoes, flip-flops, and going barefoot on hard floors entirely.

Do I need custom orthotics, or will store-bought insoles work?

For mild-to-moderate plantar fasciitis, high-quality OTC insoles (Superfeet, Powerstep) work well for about 60% of patients. Custom orthotics are worth it when: your arch collapse is severe, OTC insoles haven’t helped after 8 weeks, or you have a secondary issue like leg-length discrepancy or overpronation driving the problem. We cast custom orthotics in-office when clinically indicated — typically covered by most PPO plans.

Is plantar fasciitis the same as a heel spur?

No — they’re related but different. A heel spur is a bony calcium deposit that forms on the bottom of the heel bone; plantar fasciitis is inflammation of the fascia ligament. About 70% of patients with plantar fasciitis have a heel spur on X-ray, but the spur is rarely the source of pain. Treating the fascia inflammation resolves symptoms in most cases without removing the spur.

What stretches actually work for plantar fasciitis?

The two most evidence-supported stretches: (1) Seated towel stretch — loop a towel around your foot, pull toes toward you, hold 30 seconds, repeat 3x before getting out of bed. (2) Calf-wall stretch with a straight knee and a bent knee — targets both the gastrocnemius and soleus. Research shows stretching 3x daily reduces symptoms significantly within 8 weeks. The Strassburg sock worn overnight is the highest-impact passive stretch available.

Can plantar fasciitis come back after it heals?

Yes — recurrence rate is 15–25% in the first year without maintenance. The three biggest recurrence triggers: returning to the shoes that caused the problem, stopping stretching when pain disappears, and sudden increases in activity. Patients who continue daily stretching, wear supportive footwear consistently, and use orthotics long-term have recurrence rates under 5% in our practice.

When should I see a podiatrist for heel pain?

See a podiatrist if: pain is severe and limits daily walking, pain hasn’t improved after 4 weeks of rest and stretching, pain is getting progressively worse, you’re having pain at night or at rest, or the pain is on the back or side of your heel rather than the bottom. Night and resting pain can indicate stress fractures, nerve compression, or Achilles pathology — conditions that need imaging to rule out.

What’s the difference between plantar fasciitis and tarsal tunnel syndrome?

Both cause heel pain but feel different. Plantar fasciitis pain is sharp, focal, and worst with first steps. Tarsal tunnel pain is burning, tingling, or electric — often radiating into the arch and toes — and worsens with prolonged standing. Tarsal tunnel is nerve compression (like carpal tunnel in the wrist); plantar fasciitis is ligament degeneration. A nerve conduction study and Tinel’s sign test differentiate them. Misdiagnosis is common — about 20% of chronic plantar fasciitis cases are actually tarsal tunnel.
