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.
A risk factor is something that increases your chance of getting a disease or condition. Risk factors for a stress fracture include:

Tests may 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.
