Trigger points cause great pain, and they are created after you experience an injury or overuse a muscle. Injuries cause these points to tighten up and lose elasticity, and this causes pain in the injury's surrounding areas. Patients receive Traumeel trigger point injections directly into their trigger points, and they don't cause any side effects. The pain immediately begins to disappear after the first injection. The injection has the added benefit of encouraging further healing of the injury.
