Trigger Point Injection

What is a Trigger Point Injection? 

Trigger Point Injections are intra-muscular injections of a local anesthetic, and often an anti-inflammatory steroid, not muscle-building, into the muscle sites that are contributing to your pain.

Chronic muscular pain usually results from an injury to a muscle, such as from a sprain or strain. Pain can also develop gradually secondary to non-use of the muscle.

How do Trigger Point Injections Work?

Trigger Point Injections temporarily numb and relax the muscle sites involved in your pain complaints. This allows you to stretch these muscles more effectively than you would be able to otherwise, and also may increase blood flow through that muscle. Steroid is often used for only the first set of injections. It is thought that steroids may treat any inflammation present in these muscle sites.

How many Trigger Point Injections Do I Need? 

Obviously, if the first set of Trigger Point Injections result in satisfactorily sustained relief, then there is no need to perform any more injections. If the first set of injections provide no relief, there is no point to repeat any further Trigger Point Injections. If the first set of trigger point injections result in partial sustained relief, then a series of these injections may provide you with a greater degree of sustained relief as compared with only one set of injections.

What Can I Expect During the Procedure? 

If our pain management physician decides that trigger point injections is an appropriate treatment for your condition, this is what you can expect during the process:

  • You may be sitting or lying down for the procedure depending on where the injection sites are located
  • The area will be cleansed with an antiseptic
  • Your doctor will then place the needle into the muscle site and inject a small amount of local anesthetic
  • A Band-Aid may be applied to the injection sites
  • You should immediately attend physical therapy or proceed with stretching exercises at home to reap maximum benefit
