A stress fracture is a tiny crack in the bone from chronic overuse. Most stress fractures occur in the lower leg and foot. They can also occur in the hip and other areas.

A blow to the bone does not cause a stress fracture. Rather, it is typically caused by repeated stress or overuse. Some causes are:
Stress fractures can worsen by continued physical stress. Smoking can also make stress fractures worse because it interferes with bone healing.
Stress fractures are more common in women. Other factors that may increase your chance of a stress fracture include:
A stress fracture may cause:
You will be asked about your symptoms and medical history. The injured area will be examined for localized pain and swelling.
Imaging tests to evaluate your bones include:
Nonsteroidal anti-inflammatory drugs (NSAIDs) can relieve pain, but controversy exists about their use for stress fractures. It is possible that NSAIDs adversely affect stress fracture healing.
Rest is the most important thing you can do for a stress fracture. This includes avoiding the activity that caused the fracture and any other activities that cause pain. Rest time required is at least 6-8 weeks.
Shock absorbing shoe inserts and pneumatic braces may provide comfort and quicken recovery.
You may need crutches or a walking cane to keep pressure off the leg.
Talk with your doctor about when you can restart activity and how to progress with the amount and type of activity.
