Acupuncture is an ancient Chinese practice using thin needles inserted into the skin at specific points to relieve pain and other symptoms. It has been used for over 2000 years and works by stimulating the nervous system to release chemicals that alter bodily processes. While not proven to cure illness, studies show acupuncture is effective for pain relief from headaches, back pain, and other conditions. The interviewed patients found acupuncture eliminated their severe back pain after other treatments failed, with minimal side effects from the needle insertion. They would recommend acupuncture and undergo it again due to its effectiveness.
