The answer to this question depends on the ailment for which acupuncture was sought. If one had an injury to begin with, then one should take it easy after acupuncture. Remember, although the perception of pain may be decreased after acupuncture, the injury still exists. However, if one were receiving acupuncture for stress for example, then regular activity can resume immediately. Ask the doctor or practitioner administering your treatment for specifics as to how to take care of yourself after acupuncture.
