Unlike fractures resulting from a fall or direct impact, stress fractures are classified as "overuse" injuries, arising when the leg bones are subjected to repetitive stress that exceeds the body's natural capacity to repair and regenerate bone tissue [\[4\]](). ## Mechanism of Injury Without Trauma Bones possess a natural ability to build and repair themselves after physical activity, such as walking or running. However, when the intensity or duration of activity increases suddenly, this balance is disrupted. Muscles begin to fatigue and lose their ability to absorb shock during movement, which leads to transferring that excess load and stress directly to the bones, causing microscopic cracks over time, known as stress fractures [\[4\]](). ## Risk Factors This injury is not limited to professional athletes but can affect anyone engaging in activities that involve repetitive loading on the leg. Factors that increase this risk include: - **Sudden Increase in Training Load:** Transitioning from a low activity level to a high one in a very short time. - **Poor Nutrition:** A deficiency in Vitamin D and calcium directly affects bone strength and its ability to recover [\[4\]](). - **Biomechanics and Footwear:** Worn-out shoes or those that do not provide adequate support increase the pressure transferred to the bones. - **Lack of Sleep:** Failing to get enough rest daily hinders the natural bone repair process [\[4\]](). It is essential to distinguish between bone pain and pain resulting from other issues. In some cases, leg pain may not be related to the bones at all; rather, it could result from peripheral nerve damage or vascular issues, which requires careful evaluation [\[3\]](). To understand the difference between these injuries in greater depth, you can review our article on [Common Leg Injuries: When Is Pain Just a Muscle Strain and When Is Medical Review Needed? (Arabic)](). ## Symptoms and When to See a Doctor Pain usually begins in a specific spot on the bone. Initially, the pain may appear only at the end of physical activity and disappear with rest. As the fracture progresses, the pain becomes persistent, even during normal walking or simple daily activities. If you notice swelling at the site of pain, feel pain that wakes you from sleep, or if the pain causes you to limp, it is essential to see a doctor immediately [\[4\]](). ## Diagnosis and Treatment Stress fractures do not always appear on traditional X-rays in their early stages, so the doctor may request additional tests. Primary treatment involves "offloading" the bone, which may include complete rest from pain-causing activities, or using assistive devices like crutches if walking is painful. Returning to physical activity must be very gradual and under medical supervision to ensure the injury does not recur [\[4\]](). ## Medical references - [Peripheral Neuropathy]() - [Stress Fractures - OrthoInfo - AAOS]() General health education; not a substitute for individualized clinical assessment.
