TRIGGER POINTS ARE TINY KNOTS THAT DEVELOP IN A MUSCLE WHEN IT IS INJURED OR OVERWORKED. COMMONLY A CAUSE OF MOST JOINT PAIN, THEY ARE KNOWN TO CAUSE HEADACHES, NECK AND JAW PAIN, LOW BACK PAIN, TENNIS ELBOW, AND CARPAL TUNNEL SYNDROME.
Sometimes wrist and hand pain come from thoracic outlet syndrome. We can test for it with a nerve tension test (shown in this graphic). If you want to learn how to evaluate the nerves, this DVD Nerve Mobilization teaches that. http://www.realbodywork.com/nerve/nerve.htm
