Trigger Point Injections

During this injection, medication is placed into the trigger point to help alleviate the localized pain, as well as the referred pain from this trigger point. The medication injected is generally a combination of steroids and anesthetics.


What conditions does it treat?

A trigger point injection is generally indicated to treat painful areas of muscle or knots of muscle that can form in any muscle of the body. These knots or trigger points are oftentimes able to felt when touching the painful, affected muscle. Also, trigger points may irritate surrounding nerves and cause referred pain, or pain that is felt in another part of the body.


What should I expect during the procedure?

A small needle will be inserted through the skin and slowly advanced into the painful trigger point. Once the needle is in the trigger point, a small amount of anesthetic and corticosteroid will be slowly injected. If you have an allergy to a certain medication used in the injection, a dry needling technique (involving no medications) can also be used to perform the trigger point injection. Once the injection is complete, the needle will be withdrawn and a band-aid will be placed over the injection site.


What can I expect after the procedure?

Some patients will experience immediate relief, however, it usually takes 24 to 72 hours for the effects of the steroid medication to take effect and it may be up to 1 week before the maximum benefits are achieved. Trigger injections target the pain being caused by muscular problems. If you do not have pain relief from the trigger point injection, you may continue to require oral medications or other interventional procedures to achieve better pain relief. In general, if the injections are successful, patients will experience at least 3-6 months of pain relief after the initial series of injections. You may return for future injections when the pain returns.
