I received this e-mail from an orthopedist this morning:
A presumptive diagnosis of stress fracture is accurate. Ordering a bone scan might be considered, not likely to have results back for 10-14 days, and would not change management. The protocol would be to place patient in a firm or rigid soled shoe or a CAM walker depending on the degree of disability, limit weight bearing and activity and do a repeat plain xray in 2-3 weeks. Treatment is symptom-driven. Continued running will provoke continued symptoms. Patient could have pain for 4-8 weeks depending on activity and weight bearing , probably less if he reduces activity now.
So I have an appointment for a bone scan on Wednesday at 12:30.
