ABSTRACT: Systematic palpation can detect a trigger point; often, muscle spasms or a nodule will be present. Injection of the trigger point with a local anesthetic usually reduces pain promptly; the procedure can also effect long-term pain relief and increased range of motion. However, pain may recur and even worsen 1 to 3 days after an injection-either because additional injections are needed or because the trigger point was not completely injected. To maintain pain relief and improve strength and range of motion in the affected muscle following injection, recommend stretching exercises, physical or massage therapy, or rest. Trigger point injections can be associated with adverse effects (eg, temporary numbness, injection site irritation, and dizziness); complications include vasovagal syncope, skin infection, and compartment syndrome.
