A local anaesthetic and hydrocortisone injection combination is used when irritation causes nerves in the lower back or spinal canal to become inflamed.

What is a Caudal Epidural Injection?

A Caudal Epidural is an injection at the base of the spine near the tail bone.The epidural space lies inside the bony spine. The spinal cord and spinal nerves are contained inside a fluid filled sac surrounded by a thin skin which is called the dural membrane. An epidural injection aims to spread the injected drug just outside this covering.

Why is it done?

Epidural steroids are given for nerve pain in the legs, the pain reduction however is not permanent and the duration of pain reduction may vary. However, epidural injection may not relieve the back pain.

How does it work?

The GP at The Yardley Clinic will use is a mixture of a local anaesthetic and steroid. It may have a physical action by increasing the space around the compressed nerves. Local anaesthetics numb the nerves, giving short-term, and sometime longer term, pain reduction.

The steroids have a long-term effect by reducing swelling (inflammation) and irritation around the nerves. The steroids are not licensed for this use, but they are commonly used and we have no reason to doubt that this is a safe use of these medicines (unlicensed medications are commonly used if there are no licensed medications available to treat a particular problem).
