Trigger point injections are a type of therapy used to relieve muscle pain, particularly myofascial pain syndrome. Myofascial pain syndrome is characterized by the presence of trigger points, which are areas of muscle that are tender to the touch and may refer pain to other areas of the body. During a trigger point injection procedure, a small needle is inserted into the trigger point, and a local anesthetic or saline solution is injected. The injection helps to release the tension in the muscle, which can provide relief from pain and improve range of motion. Trigger point injections can be used to treat a variety of conditions, including tension, headaches, fibromyalgia, low back pain, neck pain, and myofascial pain syndrome. They are often used in conjunction with other treatments, such as physical therapy and medication, to provide a comprehensive approach to pain management.
