Mode of Action of Trigger Point Injection
Trigger point injections deactivate painful muscle knots by injecting a small amount of local anaesthetic, sometimes combined with corticosteroids, directly into the trigger point. This reduces inflammation, relaxes muscle fibers, and blocks pain signals. Over time, the muscle becomes less tense, leading to improved function and increased range of motion.
Trigger Point Injection
Trigger point injection (TPI) is a minimally invasive treatment designed to relieve pain and discomfort caused by tight, painful muscle knots called trigger points. Using precise ultrasound-guided techniques, the injection targets these points to relax muscle tension, reduce pain, and restore mobility. This makes TPI an effective option for patients experiencing chronic muscle pain.
Procedure of Trigger Point Injection
Identification: The trigger point is located either by manual palpation or with ultrasound guidance for greater accuracy.
Preparation: The skin over the trigger point is sterilised and local anaesthetic is applied to minimise discomfort.
Injection: A fine needle is inserted into the trigger point, delivering anaesthetic or corticosteroid to relieve pain and relax the muscle.
Post-Procedure: The area may be gently massaged, and most patients can resume normal activities shortly afterward with minimal downtime.
Ultrasound guidance enhances precision by providing real-time imaging, ensuring the medication reaches the exact trigger point.
Conditions Treated with Trigger Point Injection
Myofascial Pain Syndrome: Chronic pain from tight muscle fibres and trigger points.
Tension Headaches: Headaches caused by muscle tension in the neck and upper back.
Fibromyalgia: Widespread muscle pain where trigger points contribute to discomfort.
Chronic Muscle Pain: Persistent muscle pain and stiffness, especially in the back, neck, and shoulders.
Benefits of Trigger Point Injection
Targeted Pain Relief: Directly addresses the source of pain for localised relief.
Quick and Minimally Invasive: Fast procedure with minimal recovery time.
Improved Muscle Function: Relaxes tight muscles to restore range of motion and flexibility.
Short Recovery Time: Most patients can return to normal activities soon after treatment.
Precision with Ultrasound Guidance: Ensures accurate needle placement and effective treatment.
