I have a stress fracture in my foot: what should I know?

A stress fracture is a small crack or area of bone stress that develops when repeated impact exceeds the bone's ability to remodel. Foot pain may become more focused with activity and can later appear during ordinary walking. Limping is a sign that the foot is not tolerating its current load; continuing to run, jump or train through it can delay recovery.

The location matters because different foot bones have different healing demands. A clinician may use an examination and imaging, and may also consider training changes, footwear, nutrition and bone-health issues such as [Vitamin D Deficiency](/conditions/vitamin-d-deficiency/).

Stop impact activity until you have a clear plan, and do not use pain as a test of whether running is safe. Follow instructions about protected weight-bearing, a supportive shoe or boot, and follow-up. Keep activity to movements that your clinician has approved without increasing symptoms. A return to sport should build gradually rather than jump straight to the previous distance or intensity.

If testing shows low vitamin D, [Vitamin D Supplementation](/treatments/medical-management/vitamin-d-supplementation/) may be part of care, but supplements should be chosen with a clinician rather than taken in large amounts without advice.

Seek prompt care if pain suddenly worsens, you cannot bear weight, the foot becomes very swollen or deformed, or you develop numbness, colour change or unusual coldness. Contact your treating clinician if pain remains at rest, the prescribed support causes pressure or skin problems, or symptoms return during a planned increase in activity.

Ask which bone is involved, how much weight you may place through the foot, whether you need repeat imaging, and what milestones should come before walking, work, running or sport. Ask whether nutrition or vitamin D testing is appropriate for your situation.
