Micro-fractures are basically small cracks that develop within a bone. When these small cracks form as a result of ankle weights, they're usually referred to as stress fractures. The added weight of the ankle weights places a greater amount of force on the bones of the ankles and feet than normal, potentially resulting in a small crack.
Development
During your life, bones are continually going through a process of remodeling. Old bone tissue is reabsorbed by the body as new bone tissue forms. The repetitive stress placed on the ankle and foot from the added weight can actually increase in the resorption of bone tissue, but it doesn't do the same for its formation, which can lead to bone fatigue. This is especially true when you don't give your body enough time to recover between workouts. Eventually, the repetitive stress causes a crack.
Symptoms
Pain is by far the most common symptom of a stress fracture. This pain, however, worsens over time, especially during any weight bearing activities. Resting the ankle or foot can often improve this discomfort, but the pain returns soon after resuming daily activities. You may also notice some swelling along the outside of the ankle or the top of the foot as well as some bruising.
Diagnosis
The only surefire method of determining whether or not a small crack has formed in the bone is to talk to a doctor. Medical professionals can assess your symptoms and account for any changes in physical activity that may have contributed to a fracture. They can also run imaging tests to take a closer look at the bones in your ankle and foot.
Treatment
Reducing the load and strain placed on the affected bone is typically the first line of treatment, so don't be surprised if a doctor has you wear a brace and use crutches to allow the crack to heal. If the fracture is more severe, you may need an actual cast. To reduce any associated pain or discomfort, over-the-counter pain relievers are sufficient. That being said, you may need to avoid ibuprofen and naproxen: These medications have been known to interfere with the natural process of bone healing.
