Effects of Sever's Disease Severs disease occurs in children who are particularly physically active at the time of a growth spurt in adolescence. It rarely occurs after the age of 15 as the heel is fully developed by then. As a growth plate fuses together it then hardens into mature bone. A child may complain of tenderness in the back of the heel which gets worse during activity. Your child may have tight calf muscles or reduced range of movement at the ankle. Treatment may include massage or heat or ice therapy. Stretching calf muscles can help take the strain of the back of the heel. The physiotherapist may also recommend orthotics to add additional support and correct a child's biomechanics to prevent any further problems. Other symptoms include: Pain, swelling or redness in heels Tenderness or tightness in the back of the heels Heel pain that gets worse after bounding activates such as running or jumping Difficulties in walking Stiffness at the heel Pain that gradually resolves with rest Limping following physical activity To book an assessment or for more information please email office@manchesterneurophysio.co.uk call 0161 883 0066 .
