Most running injuries are curable and about 25% of running injuries will require consultation of a professional health care provider. Although our body is capable of adapting to stresses we put on it, an injury usually indicates a breakdown of our reparative process. Each injury progresses through 4 grades and gives us ample warning of impending problems. Most importantly, treat the cause, not the symptoms of each injury. Rest, ice, and medications may eliminate the symptoms, but the injury will return if you do not address the primary reason behind the injury (genetics, environment, training methods). Therefore, one must look for biomechanical deficiencies/imbalances, footwear, and possible training errors that may have contributed to the injury.
