What is a myofascial trigger point injection?
A myofascial trigger point injection is a minor procedure to treat a painful area in a muscle, called a trigger point. Trigger points are tight knots or bands of muscle or connective tissue that are painful to touch. They can also send pain to other body parts and cause muscle spasms and weakness.
A myofascial trigger point injection involves injecting a long-acting anesthetic, and sometimes an anti-inflammatory medicine, into the trigger point. Myofascial trigger point injections can relieve your pain and improve mobility for several days or weeks, or even longer. You can also repeat these injections as needed to maintain results.
Trigger points commonly occur in the buttocks, back and neck, but can affect almost any body part. Trigger points can be active or latent. Latent trigger points cause muscle weakness and stiffness, but generally cause pain only with pressure. Active trigger points cause pain even at rest. Trigger points can also cause other symptoms, such as headaches and eye pain.
A myofascial trigger point injection is a minor procedure, but it still involves some risk. It is only one method used to treat painful muscles. Discuss all of your treatment options with your doctor to understand which options are right for you.
