An incomplete break in the bone caused by overuse is known as a stress fracture. Symptoms can include pain and swelling. Up to 15% of all sports injuries are stress fractures. Your podiatrist needs to perform an examination and look at X-rays of the injury in order to diagnose a stress fracture.
Treatments include immobilization of the foot with the use of a cast, medications, and in some cases orthotic devices to prevent further injury.
