NERVE ROOT INJECTIONS

 

WHAT IS A NERVE BLOCK?

Nerve roots arise from the spinal cord at either side of the spine and extend from the neck to the lower back. These nerves can become pinched, inflamed or irritated within the bone tunnel in which they originate from. A nerve block is an injection of cortisone and long lasting local anaesthetic (6 hours) that gives relief from pain.  This procedure is potentially both diagnostic and therapeutic in that it can also help in locating the source of pain.  The procedure is performed under local anaesthetic.  A spinal needle will be inserted into position under the guidance of a CT scanner.  Once in the correct position the cortisone and anaesthetic will be injected into the appropriate nerve root to reduce your symptoms.
