Acupuncture is an ancient Chinese practice that involves inserting thin needles into specific points on the body to improve health. It is used to treat conditions like back pain, arthritis, nausea, and depression. While acupuncture has benefits, there are also risks like infection, bleeding or organ puncture if not performed properly. It is performed by licensed acupuncturists or physicians with acupuncture training in settings like hospitals, chiropractic offices or medical clinics.
