Overview
Trigger point injection places a small amount of anaesthetic (sometimes with steroid) into a tight muscle knot to reduce spasm and pain. Dry needling uses a thin needle without medication to release the muscle. Both are used for muscle-based pain, often as part of physiotherapy. Evidence shows benefit especially for short-term relief and improved movement when combined with other therapies.
