Trigger Point Injection

What is a Trigger Point?

Trigger points are localized areas of muscle spasm and inflammation. Trigger points can occur in various regions of the body. Common sites for trigger points include the rhomboid and trapezius muscles (which are located in the upper back and shoulder regions) as well as the lower back.

What is a Trigger Point Injection?

A trigger point injection is a minimally invasive procedure that involves an injection of medication directly into the trigger point that helps to provide pain relief. The goal of the treatment is to inactivate the trigger point, thereby reducing pain. The injections may contain a muscle relaxant (Botox) or a mixture of steroid and local anaesthetic.

 

Can anyone have a Trigger Point Injection?

If you are on blood thinners of any kind you must discuss this with the Pain Doctor, well in advance of your procedure date. If you are pregnant, you also need to inform the Pain Doctor as it may mean certain medications are not suitable for you.

What can I expect after a Trigger Point Injection?

Many people will have noticeable improvements in symptoms after a Trigger Point Injection. The reduction in pain and inflammation should, hopefully, provide a window for some rehabilitation work such as physiotherapy and exercise, which could further improve symptoms.
