Dry needling is a technique used to treat muscular pain and dysfunction by inserting thin needles into trigger points within muscles. Unlike acupuncture, it targets specific areas of muscular tension or knots. The process aims to stimulate the muscle, leading to pain relief and improved function. Dry needling is often used in conjunction with other therapies like physical therapy to enhance outcomes. Research supports its effectiveness in managing various musculoskeletal conditions such as neck pain, shoulder impingement, and chronic headaches.
