Trigger Point Injection

A Trigger Point Injection (TPI) is an effective treatment for inactivating trigger points, and providing prompt pain relief from myofascial pain syndrome. Trigger points are often tender, firm knots embedded within the muscle tissue that can be felt on examination. The pain one feels from pressing on a trigger point usually radiates in a region that is away from the trigger point. Trigger points are often located in the neck, shoulders (trapezius), low back, and buttocks. Trigger point injections contain medication designed to break the pain cycle allowing a patient to be more effective and free of pain.

What does it treat?

TPIs are used to treat pain that is caused by trigger points, which are commonly associated with myofascial pain syndrome. Trigger points typically occur in the neck, shoulders, and back. They are frequently associated with headaches as well; they can be very debilitating when severe and widespread.

How is it performed?

 A TPI is an injection that is given directly into the trigger point, which is an area of inflamed muscle and tissue. The patient is examined, and multiple trigger points are identified (typically the most painful areas). After cleaning the area, the doctor injects a combination of local anesthetic and steroid into the affected area. The procedure is typically very quick and can be done in the office without the use of x-ray or other equipment. It can commonly be done on the same day as your office visit.
