What Are Trigger point Injections

Trigger Points are small nodules that form within muscles and cause chronic myofascial pain syndrome. They can occur in various muscle groups, including the upper back, neck, shoulders, and lower back.


Micro-traumas cause Trigger Points in the muscles. For example, a micro-injury followed by inflammation leads to a hyperreactive muscle area, representing a nodule within the muscle. This nodule is palpable and causes pain and tenderness.

Trigger Point injections involve identifying Trigger Points within muscles by palpation or ultrasound and inserting a thin needle into the Trigger Point. The medication used in the injection usually consists of a combination of a local anesthetic agent and steroid medications, which help reduce inflammation and relieve pain.

How Do Trigger Point Injections Work

Trigger Point injections break up the tiny nodules that cause Trigger Points, releasing chemicals that reduce inflammation and relieve pain. Steroids have an intense anti-inflammatory action, which reduces stress on the muscles. Following the injection, physiotherapy helps in restoring muscle function.
