What causes a stress fracture?
Stress fractures are microscopic fractures of bone resulting from repeated “stress”, usually from bearing your own weight. For example, stress fractures of the feet are related to long walking, running, or other athletic activities. Stress fractures can occur in other bones of the lower leg as well as upper extremities. This particular type of fracture is often too tiny to show up on a routine xray and generally requires an MRI or bone scan to make a diagnosis.
