The boy has a condition known as Achilles Tendonitis.

When one does too much physical activity using this tendon like vigorous walking, jumping or running it results in the inflammation of that tendon. He probably has the specific type of tendonitis being the noninsertional Achilles Tendonitis. This is most common in young people.
