Needling is also used in chiropractic treatment, particularly in the form of dry needling therapy. In this approach, thin, solid needles are inserted into trigger points in the muscles to release tension and reduce pain. Dry needling is thought to work by causing a small injury at the trigger point, which leads to the release of pain-relieving chemicals and improved blood flow to the area. This therapy is commonly used to treat musculoskeletal pain, such as back and neck pain, and can be used in conjunction with other chiropractic techniques, such as manual therapy and rehabilitation exercises.
