What does the scan show?

Three-phase bone scan reveals mild hyperemia on flow and blood-pool images and focal linear cortical uptake on delayed imaging along the mid-left tibial shaft.

Why it matters

This pattern is typical of a stress fracture/stress reaction. Prompt activity modification prevents progression to a complete fracture that could require surgery.

Recommended next steps

• Temporarily reduce running mileage and impact activities; consider pneumatic walking boot if pain with daily activities.
• Ensure adequate vitamin D and calcium; evaluate biomechanics or footwear with sports medicine.
• Follow-up imaging (repeat bone scan or MRI) in 6-8 weeks if symptoms persist.

Patient tips

• Pain that worsens with weight bearing deserves rest-do not "run through" it.
• Gradual return-to-run plan after symptoms resolve, guided by a clinician or physical therapist.
