Sever's disease, also known as calcaneal apophysitis, is a common condition that affects growing children and adolescents, primarily due to repetitive stress on the heel. The pain associated with Sever's disease is typically located at the posterior surface of the calcaneus, which is the heel bone. This area is where the Achilles tendon attaches to the heel, and during periods of growth or increased physical activity, the growth plate can become inflamed and painful.

The condition is often exacerbated by activities that put additional strain on the heel, such as running or jumping. The discomfort is localized to the back of the heel, making it distinctly identifiable for diagnosis. This region's involvement is why individuals experiencing Sever's disease report tenderness and pain upon palpation at the posterior aspect of the heel.

Understanding the nature of the pain and its location helps differentiate Sever's disease from other potential issues, ensuring appropriate management and treatment strategies are employed.
