What procedure aims to alleviate pain by targeting trigger points in the muscles?

The procedure that specifically aims to alleviate pain by targeting trigger points in the muscles is Trigger Point Injection. This technique involves injecting a local anesthetic or a corticosteroid directly into hyperirritable spots within the muscle, known as trigger points, which can cause referred pain to other areas of the body. The injection helps relieve tension, reduces pain, and improves overall muscle function by addressing the underlying issues at these specific trigger points.

In contrast, ultrasound imaging is primarily used for diagnostic purposes to visualize internal organs and structures and does not alleviate pain. Epidural steroid injections are aimed at reducing inflammation and managing pain in the spinal region and surrounding nerves, rather than directly targeting muscle trigger points. A nerve block is designed to interrupt pain signals along specific nerves but is also not focused on muscle trigger points. Thus, Trigger Point Injection is the most targeted approach for addressing pain from these muscle areas.
