Nerve Root Blocks

Procedure type


Nerve Blocks are used to control nerve pain. Nerve root blocks are carried out as day case procedures under sedation using an x ray machine to localise the actual nerve targeted. The injections used are a mixture of local anaesthetic and hydrocortisone in an attempt to remove the inflammation in the targeted nerve. They can be useful in a condition which is likely to improve, for example a prolapsed intervertebral disc. Also they can be used in post operative situations to control symptoms from scar tissue.

A further use is for diagnostic purposes to ensure that the treating doctors know precisely which nerve is causing the symptoms. In most circumstances even a temporary reduction in pain will allow the treating physician to know precisely which is the nerve in trouble.

It is important to document any relief of symptoms following injection in these circumstances as this can be discussed at the review appointment.

This is aimed at reducing and identifying the source of nerve pain.

It is used to treat nerve root pain and identify the source.
