A stress fracture is caused by repeated stress or overuse from:

• Increasing the amount or intensity of an activity too quickly
• Changing to a new playing surface
• Not wearing the right shoes or wearing old shoes for a sport

Risk Factors

Stress fractures are more common in women. Things that may raise the risk of this fracture are:

• A sudden increase in activity
• Not getting enough rest between physical activities
• Playing sports that involve running and jumping, such as track and field, tennis, gymnastics, and basketball
• Having female athlete triad

Symptoms

Symptoms may be:

• Pain that is worse with activity and better with rest

Diagnosis

The doctor will ask about symptoms and past health. They will also ask about regular activities. A physical exam will be done. The doctor may suspect a stress fracture based on symptoms.

Pictures may be taken if pain is severe or fracture is not healing as expected. Tests may be:
