What Are Trigger Point Injections and How Do They Work?
Trigger Point Injections (TPIs) are a medical treatment used to target specific areas of muscle tissue that are tight, tender, or in spasm, known as "trigger points." These trigger points are often the result of muscle overuse, injury, or stress, and they can lead to localized pain and discomfort. The injection typically contains a combination of a local anesthetic or saline solution, which helps numb the area and relax the tight muscle. In some cases, corticosteroids may also be used to reduce inflammation. The injection is delivered directly into the muscle knot or trigger point using a fine needle, and the procedure is usually performed in a clinic or office setting.
The purpose of a Trigger point injection is to reduce pain and alleviate muscle tension by interrupting the cycle of muscle spasms and inflammation. When administered, the local anesthetic provides immediate relief by numbing the trigger point, while the corticosteroid or saline can help with longer-term pain reduction and muscle relaxation. This can lead to a significant decrease in discomfort and an improvement in the range of motion. Trigger point injections are often used as part of a broader treatment plan for patients with musculoskeletal pain or conditions that affect muscle function.
