A trigger point is a painful knot or tight muscle that forms when your muscles fail to relax. They are generally found in the neck, upper back and shoulder areas. A trigger point injection involves the injection or medication directly into the trigger point. It can be used to treat a wide variety of conditions including:
- Tension headache
- Myofascial pain syndrome
Trigger point injections are a simple procedure performed in the office. This outpatient procedure involves a small needle that is inserted into the trigger point and a local anesthetic. Injection of medication inactivates the trigger point and helps to alleviate or eliminate trigger point pain. Trigger point injection procedures generally take 30-45 minutes.
