Trigger Point Injection

This outpatient procedure is designed to reduce or relieve the pain of the trigger point. These small, tender knots can form in muscles or in the fascia (the soft, stretchy connective tissue that surround muscle and organs). The trigger point injection procedure takes only a few minutes to complete. In prepation for the procedure, the patient is positioned comfortably. The provider presses and pinches the skin to locate the trigger point. Once it has been identified, the provider cleanses the overlying skin. A topical anesthetic may be used to temporarily numb the skin. The provider carefully inserts a needle through the skin and into the trigger point. The provider injects an anesthetic mixture into the trigger point. This causes the trigger point to relax. If the trigger point does not relax completely after the first injection, the provider may adjust the needles position and give additional injections. When the injection is complete, the provider removes the needle. A small bandage may be placed over the injection site. The patient may be encouraged to stretch and move the muscle after the injection.
