Fractures
Fractures often result from trauma or direct injury to the bone. Stress fractures can also develop after repetitive activity, rather than a single injury. The weight-bearing bones of the foot are especially vulnerable to stress fractures, because of the repetitive forces they must absorb during normal activities like walking, running, and jumping. Symptoms include pain, swelling, tenderness at the site of the fracture, bruising, and possible heel deformity if heel (calcaneus) fracture.
