Acupuncture is a type of ancient Chinese medicine. It has been used for thousands of years, and works with over 2,000 pressure points and energy meridians in your body. As you probably know, acupuncture uses disposable needles as thin as a strand of hair placed just below the skin to stimulate these points on your body. Treatments are usually painless. At worst, patients have reported tingling, heaviness, or a slight burning sensation where certain needles are positioned.
