Sever’s Disease

Sever’s disease, also known as calcaneal apophysitis, is a common cause of heel pain in growing children and adolescents. Despite its name, it is not an illness or infection. It occurs when repeated strain irritates the growth area at the back of the heel bone.

The condition often develops during a growth spurt, when the bones may grow more quickly than the surrounding muscles and tendons. This can create tension where the Achilles tendon attaches to the heel. Children who regularly participate in running, jumping or other high-impact activities may be more likely to experience symptoms.

Pain is usually felt at the back or underside of one or both heels and may become worse during or after physical activity. The heel can feel tender when squeezed, and some children may develop mild swelling, walk with a limp or avoid placing the heel fully on the ground. Symptoms often improve with rest.

A podiatrist can assess the child’s symptoms, foot posture, joint movement, muscle flexibility, walking pattern, activities and footwear. Management is tailored to the child’s age, stage of growth and activity level. It may include temporarily modifying aggravating activities, calf stretches, supportive and well-cushioned footwear, heel cups or insoles where appropriate, and a gradual return to sport as symptoms improve.

Sever’s disease does not usually cause lasting damage and generally resolves once the heel has finished growing. However, symptoms can recur during periods of rapid growth or increased activity, so ongoing guidance may be helpful.

If your child is experiencing persistent heel pain, limping or difficulty taking part in sport and everyday activities, please get in touch to arrange an assessment. Professional advice can confirm the likely cause, provide reassurance and help your child return to activity comfortably and safely.
