Trigger point injections are a minimally invasive procedure used to treat painful knots of muscle, known as trigger points, that can develop when muscles become tight, irritated, or overworked. These trigger points may cause localized pain or discomfort that radiates to other areas of the body. During the procedure, a healthcare provider inserts a small needle into the affected muscle and injects a medication, such as a local anesthetic, saline solution, or other therapeutic agent, to help relax the muscle and reduce pain.
Trigger point injections are commonly used for conditions involving muscle pain and tension, including chronic neck pain, back pain, shoulder pain, and certain headache disorders. The procedure is typically performed in an outpatient setting and usually takes only a few minutes. Many patients experience improved muscle flexibility, reduced pain, and enhanced function following treatment, allowing them to participate more comfortably in daily activities and rehabilitation programs.
