Why are Lumbar Trigger Point Injections done?

Lumbar Trigger Point Injections are done for muscle pain. Often a part of the muscle is painful due to a dysfunction of that part of the muscle. Injecting medication into this painful point (Trigger Point) of the muscle can relieve the symptoms of muscle pain.

What causes Trigger Points?

Trigger points are commonly found in conditions called “Myofascial Pain Syndrome” and “Fibromylagia”. For reasons which are not clear, parts of the muscle get less blood flow and oxygen. This results in pain and spasms in these parts of the muscles, causing Trigger Points.

How are Lumbar Trigger Point Injections done?

Here are the steps of how a Lumbar Trigger Point Injection is done:

  1. The doctor finds the isolated painful Trigger Points by touching and pushing on the spinal muscles. These points are often marked.
  2. The skin over the Trigger Points is cleaned with an antiseptic.
  3. A small needle is placed through the skin and into the painful part of the muscle.
  4. Medication is injected through the needle. There are a number of different medications which can be injected. They could be local anesthetics, steroids, or other pain relievers.
  5. Sometimes band-aids are placed over the injection sites.

How much benefit could patients gain from a Lumbar Trigger Point Injection?

Pain relief from spinal injections can vary. Trigger Point Injections tend to be helpful for 4-6 weeks at a time, but can be repeated.
