Most trigger point injections are done in your health care provider's office. You may be told to stop taking certain medicines before the procedure. Tell your provider about any medicine allergies you have. Bring test results with you, as instructed.
During the procedure
You'll sit in a chair or lie on an exam table so your health care provider can reach the affected muscle.
-
Your provider will feel and stretch the muscle to find the exact spot of the trigger point. This may hurt, but won't take long.
-
Once the trigger point is found, it's injected. The injection may contain medicine, such as a local anesthetic, which numbs the area. A steroid medicine may be added to the local anesthetic. Ask your provider what kind of medicine they'll use.
-
If you have other trigger points, the process is repeated.
After the treatment
You can go home soon after treatment. Take it easy for the rest of the day. The injection sites may be sore for a day or so. Put ice or heat on the treated sites as instructed by your health care provider. Ask what medicines are safe to take if you need pain relief. You can return to work the same day or the day after the treatment if your provider says it’s OK.
