Sever's Disease

Sever's disease causes activity-related heel pain in growing children when the heel growth area is repeatedly stressed.

Sever's disease, also called calcaneal apophysitis, affects the growth area where the Achilles tendon attaches to the heel bone. It is seen in children and young teenagers whose heel is still developing. Repeated pulling through the tendon and pressure from running or jumping can irritate this area. It is a temporary growth-related condition, not an infection.

Heel pain is a common presentation of Sever's disease. A child may report soreness at the back or underside of one or both heels, especially during or after sport. Limping, walking on the toes, tenderness when the heel is squeezed, and tight calf muscles can occur. Symptoms often settle with rest and return when impact activity resumes. Growing pains are a separate symptom pattern, so the location and activity link help distinguish them.

The heel bone grows from a cartilage area near its back. During a growth spurt, the bone, calf muscles and Achilles tendon may not lengthen at the same pace. Sport then places traction and compression on the sensitive growth area. Hard surfaces, sudden increases in training, and footwear with limited cushioning can add load, although no single cause is responsible in every child.

Pain commonly fluctuates with activity. Reducing impact gives the irritated area time to settle, while a rapid return to sport can bring symptoms back. The condition generally improves as the heel matures, but the timing differs between children. Persistent pain, worsening limping, or pain at rest deserves reassessment to check for another cause.

Risk is higher during periods of rapid growth and in children who take part in frequent running, jumping or field sports. Tight calf muscles, reduced ankle flexibility, repeated training on hard ground, and poorly fitting or worn footwear may increase stress on the heel. Having symptoms on one side does not rule out later discomfort on the other.

A clinician usually asks when the pain started, which activities trigger it, and whether there has been a recent training change. They examine walking, calf flexibility, ankle movement and tenderness around the heel. Imaging is not always needed, but an X-ray or other test may be considered when the story or examination suggests a fracture, infection or another problem.

Care aims to reduce irritation while keeping the child safely active. A clinician may recommend a temporary pause or adjustment to impact sport, ice after activity, heel cushioning, calf stretching and gradual strengthening. Supportive footwear or custom orthotics may help distribute pressure. Paediatric physiotherapy can tailor exercises, monitor movement and guide a staged return to sport. Pain relief should be chosen with a healthcare professional, particularly for children.

Explain the pain pattern to coaches and teachers so activity can be adjusted early. A child can often continue comfortable, low-impact movement, but should not be pushed through increasing heel pain or a limp. Keep a simple record of activities and symptoms; this can reveal whether training volume, surfaces or footwear are contributing.

Sever's disease does not damage the growing child when managed appropriately, but ongoing pain can limit play and alter walking. Arrange prompt medical review for severe swelling, redness, fever, sudden injury, inability to bear weight, night pain, or symptoms that do not improve with sensible activity adjustment.

Increase training gradually, include rest days, and use sport-appropriate shoes that fit well and provide cushioning. Warm up before impact activity and maintain gentle calf and ankle flexibility. At the first sign of recurring heel soreness, reduce aggravating load and seek guidance rather than continuing until the child is limping.

A paediatric orthopaedic clinician, sports medicine clinician or physiotherapist can assess a growing child's heel pain. Look for someone experienced with children's growth-related conditions who can coordinate examination, activity advice and a gradual return to sport.
