Trigger points are localized areas of increased muscular activity and sensitivity to pain. When you palpate or massage a muscle that contains a trigger point, the trigger point feels like a “knot” in the muscle. This is the tissue component or the “mechanical” component of a trigger point. When pressure is applied to a trigger point pain is felt both locally and may radiate into distant areas. This is the neurological component of trigger points.
Trigger point injections involve injecting saline solution and medications such as lidocaine or marcaine, or a natural medication like Sarapin. The saline solution allows for an expansion of the trigger point and a mechanical breaking up of the scar tissue, adhesions, and tension of the trigger point. The medication treats the pain and neurological component of the trigger point.
Trigger point injections are safe and effective ways to treat myofascial (soft tissue) pain.
