Treatments > Myofascial Trigger Point Injection Therapy
If you are dealing with persistent muscle pain, tightness, or reduced range of motion, you are not alone. Myofascial trigger points, often characterized by localized muscle knots, can hinder daily activities and impact your overall well-being.
Myofascial trigger point injections are a specialized medical procedure designed to address the discomfort and limitations associated with myofascial pain syndrome. Whether you are seeking relief from chronic pain or aiming to enhance rehabilitation efforts, these injections can lead to a more pain-free and active lifestyle.
Trigger point injections can help soothe myofascial pain, especially in your neck, shoulders, arms, legs, and lower back.
Myofascial pain refers to a chronic condition that affects your muscles and the thin connective tissue surrounding them.
Trigger points are painful “knots” in your muscles that can be very sensitive to touch or pressure. They may form after acute trauma or by repetitive microtrauma, leading to stress on muscle fibers. It causes the muscle fibers to be stuck in a contracted state.
Trigger point injections commonly involve injections of local anesthetic with or without corticosteroid, botulinum toxin, or through dry needling, which is without any injection substance.
Healthcare providers use trigger point injections to help treat myofascial pain. “Myo” means muscle and “fascial” means fascia, which refers to the thin, white connective tissue that is wrapped around every muscle.
Myofascial trigger point injections offer many benefits for individuals experiencing pain and muscle tension associated with trigger points.
Your Journey to Holistic Health Begins Within.
Once your healthcare provider has identified the trigger point by feeling it, they will pinch the point between their fingers and stabilize the tissue. This may feel uncomfortable.
They will then insert a thin needle attached to a syringe into the trigger point and rhythmically continue needling the area by repeatedly inserting and retracting the needle without completely withdrawing the needle from the muscle or your skin.
You will most likely feel your muscle spasm or twitch. Your provider will continue the motion in multiple directions until the muscle twitching has stopped or until the muscle feels adequately relaxed.
A myofascial trigger point injection may be right for you if your trigger point pain has not improved with other treatments, such as over-the-counter pain medication, heat therapy, massage therapy, and physical therapy.
Healthcare providers typically use trigger point injections alongside physical therapy and stretching exercises to alleviate the pain. However, before they can recommend a trigger point injection, they will need to perform a thorough physical exam and rule out other possible causes of your pain, including:
Myofascial pain and trigger points are very common. They occur in about 85% of individuals at some point in their lives.
Many healthcare providers diagnose and treat myofascial pain regularly, which may include trigger point injections and/or physical therapy and stretching exercises.
Trigger points are usually painful to the touch, so you will likely experience some pain when your healthcare provider is manually locating the trigger point before the injection.
You may feel a stinging and burning sensation when your provider inserts the needle and medication. When the tip of the needle touches the trigger point, you may feel a slight increase in your pain. Although this may be uncomfortable, this pain is a good sign that the needle is in the correct spot.
Trigger point injections are typically safe and have a low risk of complications. The most common side effect is temporary discomfort or numbness around the injection site. Your healthcare provider may recommend treating this with medications such as Tylenol® or Advil®. You can also apply ice packs to injection sites to reduce the risk of bruising.
Rare complications of trigger point injections can include the following:
