Trigger point injections, also known as myofascial trigger point injections or “dry-needling”, are a form of injection therapy that targets and treats problematic areas in the skeletal muscle, or the muscle belly.
During the procedure, targeted “trigger points”, or knots of areas of muscle tightness and spasms, are injected with a liquid solution that often contains a numbing or anesthetic agent. This solution works to break up the knots or tension within the muscle.
