All joint pain occurs on the external aspect of the body, along the acupuncture channels. However, the condition is always accompanied by a deeper, systemic imbalance within the body. In Traditional Chinese Medicine, it is believed that for treatment to be effective, both the joint pain and the root cause need to be treated. Acupuncture is used to restore harmony to the body, and thereby correct the imbalance. Modern scientific research has revealed that two naturally occurring hormones provide relief from arthritis: endorphins (natural pain-killing hormones produced in the brain) and adrenalcorticotropin (an anti-inflammatory hormone). Acupuncture can be effective in stimulating the production of both endorphins and adrenalcorticotropin. As an initial treatment, acupuncture needles are used to trigger the body to heal itself by producing these hormones to relieve the pain without side effects. Further more, if it is then used on an ongoing basis, acupuncture trigger the and promoting the healing mechanism to reduce not only inflammation but also bone spurs, so as to prevent the reoccurrence of pain caused by arthritis.
