What are the symptoms of a stress fracture?

A stress fracture is a small crack caused by repeated loading that outpaces the bone’s ability to recover. Pain often begins during running, jumping, marching, or another repetitive activity and may ease with rest. As irritation progresses, discomfort can appear with ordinary walking or at rest. The painful point may be easy to identify, and the area can feel tender when pressed. Depending on the bone involved, symptoms may be felt in the foot, heel, shin, or thigh. A symptom page about persistent bone pain can help you describe the pattern, but it cannot diagnose a fracture.

Stop impact activity that brings on pain and switch to a lower-load option only if it remains comfortable. Do not test the area repeatedly by running or hopping. Arrange a clinical assessment, particularly when pain is localised, recurrent, or affecting your gait. The clinician may examine the tender area and decide whether imaging or follow-up is needed. Mention training changes, footwear, nutrition, and any history of vitamin D deficiency; supplementation should be guided by an appropriate assessment.

Seek prompt care if you cannot bear weight, pain is severe or increasing, swelling is marked, or the pain follows a direct injury. Urgent review is appropriate when a limb looks deformed, becomes cold or numb, or walking becomes unsafe. Continuing impact activity through suspected bone pain can allow a small injury to worsen.

Where is the tenderness coming from? Do I need imaging or activity restrictions? What level of walking is acceptable? Could bone-health factors, including vitamin D status, be relevant? How should I return to impact exercise?
