Understanding Trigger Point Injection

Most trigger point injections are done in your healthcare provider's office. Your healthcare provider may ask you to stop taking certain medicines. Bring test results with you, as instructed. You'll be asked to fill out some forms, including a consent form. You may also be examined.  

During the procedure

You will sit in a chair or lie on an exam table so your healthcare provider can reach the affected muscle. During your procedure:

  • Your healthcare provider will feel and stretch the muscle to find the exact spot of the trigger point. This may hurt, but will not take long.

  • Once the trigger point is found, it is injected. The injection may contain medicine, such as a local anesthetic (which numbs the area). Ask your healthcare provider what kind of medicine will be used.

  • If you have other trigger points, the process is repeated.

  • This procedure may be painful.

After the procedure

You can go home soon after the treatment. You can generally resume your normal activities after the injection. The injection sites may be sore for a day or so. The success of trigger point injections largely depends on the attention that you focus on regular stretching and good posture after you have had the injection. Put ice or heat on the treated sites as told by your healthcare provider.

When to call your healthcare provider

Call your healthcare provider if you have any of the following:  

  • Fever over 101.0°F (38.3 °C)

  • Chills

  • Redness or drainage at the injection site

  • Difficulty breathing
