Collarbone stress fracture: signs, assessment and recovery

A stress fracture develops when repeated strain exceeds the bone's ability to repair itself. In the collarbone, pain may be focused over one spot and become more noticeable with lifting, carrying, pushing or overhead sport. Tenderness or mild swelling can occur. Because collarbone pain can also come from a joint, muscle or an acute break, an examination is needed rather than relying on symptoms alone. A clinician may consider imaging and factors that affect bone health or training load.

Stop the movement or sport that triggers the pain and arrange an assessment. Avoid repeatedly testing the sore area, heavy shoulder loading and returning through worsening pain. A clinician can advise whether a sling is useful for comfort and when gentle shoulder movement is appropriate. Recovery planning should address sudden training changes, technique, nutrition and possible contributors such as vitamin D deficiency. Resume loading in stages only after everyday movement is comfortable and the treating clinician agrees the bone is ready.

Seek urgent care after a significant impact, if the collarbone looks deformed, or if bone appears through the skin. New breathing difficulty, chest pain, a rapidly enlarging swelling, or an arm that becomes pale, blue, cold, weak or numb also needs urgent assessment. Otherwise, book a prompt review when focal collarbone pain persists, recurs whenever activity resumes, wakes you at night or interferes with normal arm use.

Ask which movements need temporary restriction, whether imaging is appropriate, and what signs will show that healing is progressing. It is also useful to discuss whether your recent activity pattern, medicines, diet or bone health warrants further evaluation, and what milestones should guide your return to work, resistance training or sport.
