What Are Trigger Points & How Can Injection Therapy Help?

When muscles tighten, the knot that forms is called a trigger point.trigger-point-injection--raintree-medical-and-chiropractic-center Trigger point injection (TPI) of corticosteroids can effectively treat this painful mass of muscles and the nerves around them, which can cause pain at the site, or refer pain to a distant site in the body. Aside from pain, trigger points can lead to symptoms such as dizziness, sweating, urinary frequency, buckling of the knees, ringing in the ears, or tearing in the eyes.

Where Are The Trigger Points?

Identifying the exact location of trigger points is complex, as any of the 400 muscles of the body can develop pain or refer it elsewhere in the body. Some trigger points are considered active, as they cause pain, while others are latent and cause a decreased range of motion and weakness. Trigger points that are active can become latent and vice versa if a muscle is aggravated again.

Trigger point therapy can be used to treat muscle groups in the arms, legs, lower back, and other areas where a patient is feeling pain. A physician or chiropractor asks the patient where they are feeling pain and may press on the area to see if the pain is repeatable.

Administering TPI

Because some pain is referred from elsewhere, the practitioner may work on the presumed site of the pain, without affecting the source. When the needle causes a sharp pain or muscle twitching, he may determine he has found the source of the pain and may adjust the needle and inject the spot from a different angle. After the injection, the trigger point is inactivated, which alleviates the pain.

The practitioner often injects several sites in one visit and may repeat the procedure additional times. While a medication such as cortisone is often used in the injection, in some cases where the patient is allergic to a particular drug, just dry-needling the site without using medication can help to reduce pain.

Cortisone shots are used for conditions such as osteoarthritis, rheumatoid arthritis, tendinitis, and bursitis in addition to trigger points. They can also be used to treat tension headaches, fibromyalgia, and myofascial pain syndrome. For any of these conditions, other treatments to lessen pain include physical therapy, exercise, and massage.

Using TPI is not recommended for patients who are pregnant, who have local or systemic infections, are on steroids, have diabetes, or those who have a high risk of infection. The doctor will exercise care for those with bleeding disorders or anticoagulation problems.
