How can the way I move cause me chronic pain?

Most chronic pain is the result of years of poor movement habits -- habits that have taken on the guise of "natural" movement, even though these are actually unnatural and harmful habits (also called movement dysfunctions or movement faults). For instance, you will discover that many people who experience shoulder or elbow pain have shoulder blades that don't move well. The shoulder blade is supposed to help the arm and forearm move. When it doesn't move well, the shoulder or elbow joints must then move more than they usually do. This excessive movement causes pain. Correcting these issues results in patients sensing they are using their arm in a different way -- yet it feels better.
