Sever’s disease also known as calcaneal apophysitis, is a common condition situated at the back of the heels in children usually aged between 9 and 13 years old. Pain is due to the inflammation of the growth plate of the calcaneus (heel bone). When the body is growing rapidly the soft tissue can lag behind in terms of lengthening and combined with other factors such as high activity load, hardsports surfaces, flat shoes including sports shoes such as football boots, weak calf muscles and poor foot mechanics, can lead to pain.
