This is what we all learn in school. This is also called TCM. It entails the placement of needles at or close to the site of pain or dysfunction. If the neck hurts, you put needles in the neck; if the knee hurts you place needles in the knee. It also works with internal issues such as digestion. If your stomach is hurting the needles on the abdomen are used. This can be a very effective treatment for many, many patients.
