In our pursuit of healthy bodies, pain can be an enemy. In some instances, however, it is of biological benefit. Pain that occurs right after an injury or early in an illness may play a protective role, often warning us about the damage we've suffered.
When we sprain an ankle, for example, the pain warns us that the ligament and soft tissues may be frayed and bruised, and that further activity may cause additional injury.
Pain, such as may occur in our heels, also alerts us to seek medical attention. This alert is of utmost importance because of the many afflictions that contribute to heel pain.
