Many people make the mistake of returning to their normal activity or sport before they are physically ready. You may not be feeling any more pain but the injury and the time you have spent not training reduces aspects such as muscle strength, proprioception and flexibility. This means that you are at a higher risk of injury in the future. 

Many people struggle with chronic pain because they never dealt with the injury comprehensively when it first occurred. Specific exercises need to be performed in order to restore muscle activation, proprioception, strength and flexibility in order to allow the individually to perform at an optimal level.
