Relieve pain caused by Trigger Points with the Trigger Point Injection.

Trigger point injections are a treatment modality that can offer prompt relief for those in pain. These injections are typically easy to perform in the office and can provide valuable pain relief.

  • Trigger point injections are used to deactivate a trigger point, which is an area of painful muscle spasm.
  • Trigger point injections can provide relief from myofascial pain syndrome, fibromyalgia, and tension headaches.


Use of Trigger Point Injections

These trigger points produce pain both at the site and referred pain to the surrounding area, and the pain can be associated with decreased ability to move comfortably. While the pain occasionally responds to physical therapy, trigger point injections have been shown to lessen the pain and release the muscular and soft tissue tension. Trigger point injections should be avoided if you have an infection at the site of your pain, such as cellulitis.

The Procedure

A trigger point injection is an easy, low-risk procedure that can be performed quickly in your doctor’s office. Usually, your health care provider prepares an injection of pain medications, such as a combination of an anesthetic and an anti-inflammatory medicine, to insert into the targeted area. It has been suggested that merely the use of a needle placed into the area of pain can deactivate the trigger point, but this has yet to be proven in medical studies. The medications used in the injection are usually a combination of long-acting and fast-acting medicines to give you immediate relief in the office and to provide pain relief in the time that follows.


How It Works

Trigger point injections may interfere with the nerve signals sent out by the abnormal muscle and nerve endings causing the pain. This could be done by a release of potassium from cells where the injection was placed, which changes the cell signal transmission. Pain relief may also come from the injection of fluid into the area of pain, which can dilute the pain hormones so that the body does not detect them as well. Additionally, the medications used may numb the area, and then it cannot send as many pain signals to the central nervous system.


There are some important things for you to know regarding a trigger point injection procedure. It is recommended that patients rest for one or two days after the injection and avoid strenuous activity. During that rest time, it is important to stretch the muscle groups affected and use full range of motion. Trigger point injections are not usually injected very deeply below the skin, but whenever an injection is given, there is the potential for infection after the procedure. It is important to care for the area as directed by your health care provider, and report any redness, pain, or swelling to him or her immediately.

Trigger point injections are a fast and effective treatment option for patients with pain, and the treatment carries little risk. If you have persistent pain from muscle spasms, consider discussing this with your provider right away.
