Why do I need this injection?
You have pain in the back, leg or arm possibly caused by wear and tear in the facet joints in the spine. Injecting the facet joint can help relieve the pain.
What is the aim of the treatment?
The aim of a facet joint injection is to give local anaesthetic and a long acting steroid close to the nerve root as it leaves the spine. This produces an anti-inflammatory effect and can relieve the arm or leg pain.
Facet joint injections can be used in two ways:
- As a diagnostic tool to confirm whether the facet joint is the cause of the limb pain.
- As a treatment for the pain, repeated as necessary.
How long will the pain relief last for?
Pain relief varies for each individual. Your pain may:
- be relieved completely and not return
- be reduced for several weeks and then return, but is not as bad
- be reduced for several weeks but return as bad as it was.
