There are several subtle symptoms and signs when proper joint function and balance begin to break-down. Sometimes the symptoms may be noticeable, such as stiffness or fatigue when assuming a certain work posture too long, the occasional headache for seemingly no reason, or decreased performance in a sport or another task. Once even subtle symptoms as these are noticeable an imbalance and potential for injury have already progressed significantly. The doctor is highly trained to find the signs of tension, imbalance, and dysfunctional joint movement before even the subtle symptoms become evident, stopping a painful or exacerbative episode in its tracks and keeping you loose, happy, and in optimal health.
