LegStress Fracture
A stress fracture is a tiny crack in a bone caused by repetitive force, often from overuse. They most commonly occur in the weight-bearing bones of the foot and lower leg and are frequent in runners and athletes who rapidly increase training.

Frequently Asked Questions
What is a stress fracture?
A stress fracture is a small crack in a bone caused by repetitive stress rather than a single injury. It commonly occurs in the lower leg or foot. It can worsen if not treated early.
What causes a stress fracture?
It is caused by overuse, repetitive impact, or sudden increases in activity. Poor nutrition, footwear, and bone health can contribute. Athletes and runners are at higher risk.
What are the symptoms?
Symptoms include localized pain that worsens with activity and improves with rest. Swelling and tenderness may be present. Pain can become constant if ignored.
How is it treated?
Treatment requires rest from impact activity and sometimes protective footwear or a boot. Healing depends on reducing stress on the bone. Early diagnosis helps prevent worsening.
How long does recovery take?
Recovery typically takes 6 to 8 weeks but varies by location and severity. Return to activity should be gradual. Pain-free walking is an important milestone before returning to sport.
