Emotions may form a valuable part of diagnosis. So, for example, being overly worried can be an indication of excess in the spleen and stomach. TCM Practitioners use a range of diagnostic skills, including listening to the stomach and spleen pulse at stage 2 on the right hand, and asking a range of structured questions.
Emotions and physical symptoms can feed off each other, of course, and catching things early to break a cycle can be very important. Some things change over time and as they do, your discovering of new ways to approach optimal health means you gain valuable new resources.
