What are trigger point injections?
Injections into trigger points can help to treat lower back pain. One or more trigger points can cause the pain and tenderness associated with myofascial referred pain around your back or in your legs.
An injection into a trigger point can relieve myofascial pain, particularly in the lower back, neck, shoulders, arms, and legs. Your muscles may have painful trigger points that are tender to pressure or contact and cause pain in movement. They may develop as a result of recent trauma or from repeated microtrauma that stresses the muscle fibres. The muscle fibres become constricted as a result. When you rub your muscle, these knots can occasionally be felt. Local anaesthetic injections with or without corticosteroids are frequently used for trigger point injections.
