Stress Fracture
Moderate
A stress fracture is a small crack in a bone caused by repeated stress rather than a single major injury. It commonly affects the bones of the lower leg and foot, particularly in people who participate in running or other repetitive impact activities. Pain usually develops gradually and becomes worse with activity.

When to Seek Medical Attention
Stress fractures require medical assessment because continuing to place stress on the affected bone can worsen the injury. Seek care for persistent localized pain that increases with activity, swelling, or difficulty bearing weight. Prompt evaluation is appropriate for severe pain, inability to bear weight, or symptoms suggesting a complete fracture.

Overview
A stress fracture is a small crack in a bone caused by repeated stress rather than a single major injury. It commonly affects the bones of the lower leg and foot, particularly in people who participate in running or other repetitive impact activities. Pain usually develops gradually and becomes worse with activity.
Symptoms 2
Increased Thirst
Muscle Pain
Causes 1
Stress fractures develop when repeated physical stress causes microscopic damage to a bone faster than the body can repair it. A sudden increase in training intensity, running on hard surfaces, repetitive jumping, or prolonged physical activity can contribute. Reduced bone strength or inadequate nutrition can also make bones more vulnerable to stress injury.
Sedentary Lifestyle
Risk Factors
Stress-fracture risk increases with sudden increases in exercise duration, intensity, or frequency, especially running and other repetitive impact activities. Previous stress fractures, inadequate recovery, low energy intake, poor nutrition, reduced bone density, certain menstrual or hormonal problems, and inappropriate training surfaces or footwear may also contribute.
Diagnosis
Diagnosis is based on a patient's medical history,
symptoms, physical examination and, when necessary,
laboratory or imaging investigations.
A stress fracture is diagnosed from the history of gradually developing activity-related pain and a physical examination. Early X-rays may appear normal, so repeat imaging or MRI may be needed when suspicion remains high. Bone scans or other imaging can sometimes help identify the affected bone. The clinician may also assess training, nutrition, and other risk factors.
Prevention
Key Prevention Tips
Stress fractures can often be reduced by increasing exercise gradually and allowing adequate recovery between demanding activities
Use appropriate footwear and vary training surfaces when possible
Adequate energy, calcium, vitamin D, and overall nutrition support bone health
Persistent or worsening pain during activity should be evaluated rather than ignored or trained through
Prevention Guidance
Stress fractures can often be reduced by increasing exercise gradually and allowing adequate recovery between demanding activities. Use appropriate footwear and vary training surfaces when possible. Adequate energy, calcium, vitamin D, and overall nutrition support bone health. Persistent or worsening pain during activity should be evaluated rather than ignored or trained through.
Reminder: Prevention recommendations should be tailored to your personal health status and risk factors.
