Acute Pain Management

Trigger Point Injections (TPI)

Overview

Trigger Point Injection (TPI) is an injection used to treat myofascial pain syndrome, or chronic pain that involves tissue surrounding muscles. Many muscle groups in the arms, legs, lower back, and neck are treated with TPI.

What is a Trigger Point?

A trigger point is a tight knot, or band of muscle, that forms when a muscle does not relax. The knot can usually be felt just under the skin and may involuntarily move when touched. This trigger point can irritate surrounding nerves and cause pain in another area of the body, called referred pain.  Over time, loss of range-of-motion, scar tissue, and weakness may arise.

The Injection

A small needle containing a local anesthetic, sometimes containing a corticosteroid, is inserted into the trigger point.  The injection of this medication alleviates pain and inactivates the trigger point. The injection is an in-office procedure generally taking approximately 30 minutes.
