ACUPUNCTURE
Acupuncture is a method of treating certain disorders by inserting needles into various body parts. It was developed in China about 2,000 years ago.
It works by using "trigger points", which are areas of the body, usually in muscle, that are painful and cause the pain to radiate to other places, which may be some distance away from the trigger point. Inserting an acupuncture needle into the trigger point can relieve pain in these and distant areas.
Acupuncture still works when there are no trigger points. This suggests that acupuncture changes how the central nervous system (brain and spinal cord) transmits information about pain.
Acupuncture does have measurable effects on the body, even though we can't explain them all in detail. You don't have to believe in it for it to work!
