Myofascial Trigger Points are tight, knotted muscle areas that cause pain, restricted movement, and referred symptoms like headaches or limb pain. Often found in the shoulders, they form from minor muscle damage. Acupuncture effectively treats these points by boosting blood flow, stimulating nerves, and releasing endorphins to ease pain. Whether using deep or shallow needling, clinical trials show consistent benefits. The treatment is usually painless and promotes healing in both muscles and tendons.
