More than 25 million people in the U.S. live with chronic pain. This is pain that lasts for more than three months. The most common type of chronic pain is chronic back pain.
Often, no physical cause for this pain can be found. In these cases, it may stem from brain changes that persist after an injury healed. These brain changes provide a warning for you to restrict your movement and let the body recover. But in some cases, they can cause the pain to persist long after the damage has healed.
