Trigger point injections are used for specific muscles that are causing pain. They are knots and areas of spasm within in the muscles. They remain contracted and can be extremely painful. Trigger point injections are designed to relax the muscular trigger points thus reducing the pain. The injections are done with needles and injections may include: Steroids, local anesthetics e.g. Novocain, B12 and even “dry needling”. The trigger points are first identified and then injected. This causes the trigger point to become inactive and as a direct result alleviates pain.
