Acupuncture is a component of the health care system of China that can be traced back at least 2500 years ago. The general theory of acupuncture is based on the Traditional Chinese Medicine theory that there are patterns of energy flow (Qi) through the body that are essential for health. Disruptions of this flow are believed to be responsible for diseases. Acupuncture practitioners choose specific points to place the needles based on your condition. Up to 12 points may be used during a typical session, sometimes more depending on the number of symptoms you have. You may feel a tingling or a dull ache when the needles are inserted but shouldn't experience any significant pain. If you do, let your practitioner know straight away. In some case, your practitioner may rotate the needles or stimulate them with a mild electric current (know as electro acupuncture)
