Sever's disease is heel pain in a growing child caused by irritation at the growth plate on the back of the heel bone — the spot where the Achilles tendon pulls on the calcaneus. It is not an infection, a true "disease," or a permanent injury. It's an overuse condition that shows up during growth spurts and settles down once the growth plate matures and the underlying training load is dialed in.
Parents almost always describe the same picture: a soccer, basketball, gymnastics, or track kid between roughly age 8 and 14 who starts limping after practice, favors the affected side climbing stairs, and squeezes their heel in the car ride home. Pressing on the sides of the heel bone reproduces the pain. Mornings and the first few minutes on the field are often the worst. The diagnosis is usually made in the exam room, without imaging, and the treatment is far more about training load than it is about medication.
What Sever's disease really is
The heel bone in a growing child isn't one solid piece. It has a separate growth center at the back — the calcaneal apophysis — that stays cartilaginous until it fuses to the rest of the bone in the mid-teens. The Achilles tendon inserts directly onto that growth center. During growth spurts, bones lengthen faster than the calf muscle and Achilles can stretch to keep up, so the tendon effectively pulls harder on a growth plate that is still soft. Add the repetitive impact of running and jumping, and the growth plate becomes inflamed and painful. That inflammation is what causes the symptoms; the growth center itself is not fractured or damaged in any lasting way. The AAOS reference page on Sever's disease describes the same mechanism.
Who gets it — and when
Sever's disease is most common between ages 8 and 14, roughly the years bracketing peak growth. Kids who play running and jumping sports — soccer, basketball, football, gymnastics, cheer, track, and lacrosse — are the classic group, but we also see it in kids who just started a season on hard turf or moved from cushioned trainers into flat cleats. Both heels are affected in a meaningful share of kids, though one side is usually worse. Body weight, calf tightness, and pronated ("flat") mechanics can all make it more likely, and a growth spurt in the last few months is a very common trigger.
It rarely occurs in kids much younger than 7 or in teens whose growth plates have already closed. In an older adolescent whose heel pain looks like Sever's but keeps flaring after the growth center should have fused, we go looking for something else — insertional Achilles tendonitis, a calcaneal stress reaction, or a bursitis, for example. Adults with heel pain almost always have a different problem: read our overview of adult heel pain for that side of the spectrum.
Symptoms that fit the diagnosis
The pattern is fairly specific. Kids with Sever's typically report:
- Pain at the back or bottom of the heel, worse during and after running or jumping
- Tenderness when the sides of the heel are squeezed together — the classic "squeeze test"
- Stiffness and soreness with the first steps out of bed or after sitting
- A visible limp late in practice or on the walk to the car
- Tight calves and difficulty pulling the toes up toward the shin
- Symptoms in both heels in a fair number of cases, though one is usually worse
Redness, warmth, or a distinct lump on the back of the heel are not typical for Sever's and push us to consider other diagnoses.
How we diagnose it in the office
Diagnosing Sever's is usually straightforward. We take a history — sport, position, recent growth, shoe changes, new turf, minutes on the field per week — and examine the foot. Pressing side-to-side on the heel bone reproduces the pain in most kids with Sever's, while pressing on the Achilles tendon itself or the bottom of the arch usually does not. We check calf flexibility, look at the child's standing arch, and watch a few steps of walking to see how the foot is loading.
X-rays are not required to make the diagnosis, and imaging findings alone can't confirm Sever's — the growth center often looks fragmented on an X-ray in a completely healthy child, so the picture only makes sense in context. We do order imaging when the story doesn't fit: sudden pain from a specific fall, pain that wakes the child at night, swelling, redness, a limp with no clear activity trigger, or symptoms that fail to improve with rest. Those features can point to a stress fracture, a bone cyst, or an infection, and they need to be ruled out rather than treated as Sever's. This is the same logic we apply to warning signs in a child's foot more broadly.
What actually treats it
Sever's responds to load management, not medication. The core plan has four parts, and each matters:
- Modify the load, don't just rest. A total shutdown for weeks usually backfires — the child loses fitness, the family loses the season, and the calf gets tighter. Instead, cut running and jumping volume by roughly half for two to three weeks, drop the hardest sessions, and let the child stay in low-impact activity (swimming, cycling) so they keep moving without hammering the heel. Return to full training only once the heel is quiet with normal walking and the squeeze test no longer hurts.
- Cushion and elevate the heel. A pair of soft heel cups in every pair of shoes the child wears — cleats, sneakers, everyday shoes — spreads the impact and slightly relaxes the pull of the Achilles on the growth plate. Kids in unusually flat shoes (some cleats, some running flats) often improve quickly just from adding a cushioned heel insert.
- Stretch the calves — daily. Tight calves are the mechanical driver almost every time. Straight-knee and bent-knee calf stretches held for 30 seconds, two or three sets each side, done daily and before practice, take pressure off the growth plate. Rolling the calf and the arch with a lacrosse ball or a foam roller helps kids who tolerate it.
- Ice after activity. Fifteen to twenty minutes of ice on the heel after practice or a game is a simple way to blunt post-activity soreness while the plan is taking hold.
Over-the-counter ibuprofen is reasonable for a bad flare after a game, dosed by weight and used for a few days at a time — not as a way to keep playing through pain. When symptoms are severe enough that a child limps with normal walking, a short course in a walking boot for one to three weeks can quiet things down before we transition back through the load-management plan above.
Kids with clear pronation or a very flat, collapsing arch sometimes benefit from a supportive custom orthotic once the acute pain has settled. That's a discussion for the follow-up visit, not the first day. Cortisone injections are not part of standard care for Sever's — we do not inject growth plates in children.
Returning to sport safely
The most common reason Sever's drags on is a rushed return to full training. A workable stepwise progression looks like this: pain-free walking first, then pain-free jogging on grass at half pace, then straight-line running at practice pace, then change-of-direction drills, and finally full contact and game minutes — moving up a step only when the previous step is pain-free during the activity and the next day. Most kids move through the whole ladder in two to four weeks once they start it, though the timeline is individual and should be paced by how the heel actually responds.
Season-long communication with coaches matters here. A single game where a kid played 90 minutes on hard turf can undo two weeks of progress. So can a jump from one sport straight into another with no offseason. We encourage families to keep at least one truly low-impact day each week during the season and to build in a real break at the end of it before starting the next sport.
Preventing it — and preventing another flare
You can't prevent a growth spurt, but you can prevent most of the training conditions that turn a growth spurt into Sever's. Rotate two pairs of athletic shoes so cushioning has time to recover. Replace worn cleats and running shoes before the season starts, not during it. Keep single-sport specialization in check for kids under 14 — the same joint being loaded the same way year-round is a setup for overuse. Build calf-stretching into the pre-practice routine, not just the physical therapy plan after pain starts. And bring us in early if a child limps for more than a few days: a two-visit plan at the first sign of Sever's is far shorter than a mid-season rescue after weeks of pushing through.
If your child's heel pain doesn't sound like a straightforward case — for example, it started after a fall, one heel is visibly swollen, or symptoms don't respond to two weeks of load management — we should see them sooner rather than later. The broader picture of when heel or foot pain in a growing child warrants an evaluation is covered in our parents' guide to common foot problems in kids. Sever's is very treatable, but only when the diagnosis is right.
When to call our office
Call the clinic if a child's heel pain limits normal walking, wakes them at night, doesn't improve after a couple of weeks of shoe changes and cutting back on running, or is accompanied by swelling, warmth, redness, or fever. Same-day evaluation is appropriate for a heel that will not bear weight at all after an injury, or any acute foot injury with obvious deformity. You can request an appointment at our Farmington or South Ogden office, or call the location closer to you.
