Doctors use trigger point injections to treat chronic muscle pain and other issues that affect the musculoskeletal system.
These types of injections are highly effective in treating the following conditions:
Muscle pain can develop for a variety of reasons, from sleeping in the wrong position to tearing large muscle groups during an intense weightlifting session.
Although many types of muscle pain resolve after a few days of rest, people who have persistent or chronic muscle pain may require medical treatment.
Chronic muscle pain can have a significant impact on a person’s ability to function and their quality of life. Trigger point injections may offer immediate benefits to people who have chronic muscle pain.
Below, learn about the uses, efficacy, side effects, and risks of trigger point injections. Trigger point injections may treat chronic muscle pain related to myofascial trigger points, which are highly sensitive bundles of fibers in tight bands of muscle.
The treatment involves injecting medication directly into myofascial trigger points. The doctor will determine the best type of medicine based on the severity and underlying cause of the pain.
Trigger point injections can include: a local anesthetic, such as lidocaine, which blocks pain receptors in muscles
Trigger point injections may help relieve symptoms of myofascial pain syndrome, a chronic pain condition that affects the muscles and their surrounding tissue.
In myofascial pain syndrome, trigger points stimulate pain responses in seemingly unrelated parts of the body. This phenomenon is called referred pain.
Trigger point injections can reduce localized muscle pain by relaxing the affected muscles, and researchers Trusted Source believe that the injections interrupt the nerve signaling pathways that cause referred pain.
Possible causes of myofascial trigger points include:
injury or trauma to a muscle
In addition to referred pain, a person with myofascial pain may experience:
pain in specific parts of a muscle
pain that intensifies when the person moves or stretches the affected muscle
muscle knots that the person can feel by touch
muscle stiffness or weakness
a limited range of motion
