Fractures are breaks in the bone that are often caused by a blow or a fall.
Most fractures occur in the arms and legs. Symptoms may include tenderness over the bone, swelling of the affected area, deformity of the limb, and increased pain upon movement. Stress fractures are weak spots or small cracks in the bone caused by continuous overuse. Stress fractures often occur in the foot after training for basketball, running, and other sports. A stress fracture may not cause swelling.
