The inflammation is called achilles tendonitis. It is common among people who run and walk a lot and have tight tendons. The condition occurs when the tendon is strained over time, causing the fibers to tear or stretch along its length, or at its insertion on to the heel bone. This leads to inflammation, pain, and the possible growth of a bone spur on the back of the heel bone. The inflammation is aggravated by the chronic irritation that sometimes accompanies an active lifestyle and certain activities that strain an already tight tendon.
Bone bruises are common heel injuries.
A bone bruise or contusion is an inflammation of the tissues that cover the heel bone. A bone bruise is a sharply painful injury caused by the direct impact of a hard object or surface on the foot. Stress fractures of the heel bone also can occur, but these are less frequent. Children's Heel Pain Heel pain can also occur in children, most commonly between ages 8 and 13, as they become increasingly active in sports activity in and out of school. When the bones mature, the problems disappear and are not likely to recur.
