A nerve block injection, often called ‘perineural injections’, is an injection to help reduce the nerve inflammation and sensitivity that can cause the generation of pain signals within the nerves from a specific area of the body.

Why do I need nerve block injections?

These injections typically contain a mixture of local anaesthetic and depot corticosteroids (the type of steroid that reduces inflammation) and work by temporarily reducing or ‘blocking’ pain signals in the nerves being treated.

Nerve block injections can help many, but not all types of pain. They can often be very helpful when diagnostic tests, such as MRI scans, have identified a probable underlying cause of nerve pain that’s likely to respond well to the treatment. In addition, nerve blocks can be very effective in reducing the pain of shingles and post-shingles neuralgia, and can reduce permanent damage to the nerves affected by the shingles if carried out soon enough. Nerve blocks can also be used to help determine the root cause of pain when other tests haven’t been conclusive. If the injection is effective, this can indicate which further treatments may be suitable for longer-term management of the patient’s pain. Symptoms and conditions most typically treated by nerve block injections, include sciatica, back, arm, shoulder and neck pain linked with nerve irritation originating in the spine, sacroiliac and coccyx pain, certain types of facial and jaw pain, plus nerve and joint pain in the hands, knees and feet.

The procedure

Nerve block injections are usually administered by a specialist consultant in an operating theatre. You’ll be asked to change into a surgical gown and your consultant will talk you through what’s going to happen beforehand. Depending on the area being treated, X-ray or ultrasound will be used to help guide the injection into the correct location, and local anaesthetic is applied first to numb the area. Sometimes, sedation is also used in order to make the procedure more comfortable for you. This will be administered by an anaesthetist and means that, while you won’t be asleep, you’ll be more relaxed.

Aftercare

If sedation was used, you may be groggy afterwards, and this will be monitored briefly before you go home. You won’t be able to drive for at least 24 hours, until the sedative has completely worn off, so you will need somebody to accompany you home. There may be some bruising and soreness at the site of the injection, but this should settle within a few days. In more rare cases, there may be some temporary weakness or floppiness in the limbs linked with the nerves being treated. Your consultant will be able to discuss side-effects with you and how to manage these.

Nerve block treatment is not usually 100% effective, and the results aren’t always immediate. However, many people experience very significant improvements that can last anything from a number of days to many months, during which time, the problem can settle, and be further helped by specialist physiotherapy.

Nerve Root Injections, Epidurals and Facet Joint Injections

Why do I need these injections?

Nerve root injections and epidurals are used to treat pain originating from nerves and discs within the spine, and facet joint injections can settle pain coming from these small spinal joints. This can include pain coming anywhere from the cervical spine (neck) to the coccyx (tail bone); pain associated with spinal arthritis, and pain associated with nerve compression and irritation due to herniated discs and spinal stenosis, such as sciatica and low back pain. They can also be used to treat arm pain associated with stenosis or disc herniations within the cervical spine (neck).

Nerve root injections are essentially the same as nerve block injections but are targeted specifically at certain nerve roots. The injections typically contain a mix of local anaesthetic and depot cortico-steroid (steroid) and work by temporarily reducing inflammation and pain signals in the nerves being treated.

This means nerve root injections aren’t suitable for all types of pain and are generally only used if diagnostic tests, such as MRI scans, have identified a probable underlying cause that’s likely to respond well to the treatment. However, they can also be used to help determine the root cause of pain when other tests haven’t been conclusive. If the injection is effective, this can indicate which further treatments may be suitable for longer term management of the patient’s pain.
