  • Departments: Pain Medicine

Introduction

This leaflet has been produced to give you general information about your treatment.  This leaflet should have answered most of your questions.  It is not intended to replace the discussion between you and the healthcare team but may act as a starting point for discussion.  If after reading it you have any concerns or require further explanation, please discuss this with a member of the healthcare team.

What is an occipital nerve injection?

An occipital nerve injection is an injection around a peripheral nerve known as the occipital nerve situated at the back of the head. The injection contains local anaesthetic often with a small amount of steroid.

Who I need an occipital nerve injection?

An occipital nerve block may be done as a test to determine the source of your pain and/or to relieve your pain.  If you get a period of sustained pain relief from the injection, it will help the doctor decide which procedure to do next.

Can there be any complications or risks?

As with any procedure, side-effects may occur. However, these are usually minor and there is little risk of serious harm.

Side-effects may include:

  • Mild local tenderness and/or bruising at the site of the injection, that usually settles over the first few days.
  • During the injection, you may experience signs of local anaesthetic toxicity if the injection is passing into a blood vessel. You should inform your doctor immediately if you develop tingling around your mouth or a metallic taste, ringing in your ears, feeling drunk, dizzy, blurred vision, muscle twitches or difficulty in breathing
  • The local anaesthetic may rarely spread causing some numbness and/or weakness in the upper limb. Should this occur, the effect is temporary and will rapidly resolve over minutes or rarely hours
  • Infection. This is rare. You should seek medical help if there is local warmth or redness over the site of injection with tenderness and/or you feel hot and unwell. This may require antibiotic treatment
  • Nerve injury is very rare
  • Injection treatments are not always effective and may not help your pain
  • Localised alopecia

I have heard that steroids are being used  unlicensed/off-label, what does this mean?

Steroid medications (corticosteroids) are licensed for use through specific routes of administration only. However, for managing chronic pain they are in use through variety of routes for number of years and some routes of administration to treat pain are not on license. This is referred to as off-label use. The manufacturer of the medicine may not have applied for a specific licence to extend its usage.

Many medicines used in pain medicine are used off-label. You can discuss this further with your doctor.

The following information has been produced to ensure that you are able to have your pain relief procedure.  It is essential that you read and follow the advice given below before you come to the hospital. If you do not follow the advice you may not be able to have your treatment.

You may have to wait a while before your procedure, so please bring something to read or do to keep yourself occupied. Please bring a dressing gown and slippers to wear.

Please leave any valuables or jewellery at home.  It is essential that after the procedure you arrange for an adult friend or relative to collect you by car or taxi. You will not be able to use the bus or train to travel home.

Hospital transport may be available if there is a medical need. If you think you may be eligible, please contact the doctor.

Advice for diabetic patients only

Your blood sugar level may raise and remain raised for few days after the procedure due to steroid medications that might be used during the injection. It is advisable to monitor your sugar level regularly for one week following the procedure.  Any concerns please contact your doctor.

What happens before the procedure?

You will be admitted by the nursing staff who will ask for and record some information about you.  Your blood pressure will be checked and you will be given a gown to put on. The doctor will explain the procedure and ask you to sign a consent form.  Please make sure you have understood what has been said and feel free to ask any questions.

What to expect during the procedure

As a precautionary measure, a thin plastic tube (cannula) may be inserted into a vein in your arm/hand before the procedure itself.  This allows us to give medication if there are any issues during the procedure.

Regarding the procedure itself, after cleaning your skin with antiseptic solution, local anaesthetic will be injected into your skin to numb it.  Under X-ray screening or ultrasound guidance, a fine needle is introduced towards the area to be treated.  Once the optimal position is obtained, local anaesthetic with or without steroid will be injected close to the nerve.

What happens after the procedure

You will be taken on the trolley to the recovery area where the nurse will check your blood pressure and pulse.  You will be asked to rest for about an hour.  After that you will be able to get up, but please check with the nurse before you do so.

Once you are mobile, you will able to go home accompanied by an adult friend or relative.

Please ensure that you have arranged for someone to drive you home after this procedure.  Failure to do so will result in your procedure being cancelled. You should not drive for the next 24 hours after the procedure

What to expect when you return home

Take it gently for a few days but gradually build up your activities. You should continue to take all your usual medication/pain relief as the pain may be slightly worse until the nerve block starts to work.

Some people find that they get relief from their pain but, after a couple of months this wears off.  Others may experience complete relief; however, there is a chance that the pain will not improve, not change or will get worse.

Try not to overdo things on a good day as this may result in you experiencing more pain the following day.

Follow-up appointment

A letter will be sent to your doctor and you will be reviewed either by telephone or seen at the Pain Service in due course.

At this review you will be asked to discuss the Pain Diary you were given at your injection appointment, please have this completed diary to hand at the time of the phone call.

Points to remember

You will need to have arranged for someone to drive you home after this procedure.

  • Please bring your glasses if you need them for reading.
  • Always bring a list of all current medication.
  • Continue taking all your usual medication on treatment day (please see above advice if you are a diabetic patient)
  • If there is any possibility you may be pregnant please inform the doctor or nurse.
  • If you are planning to travel abroad or fly within two weeks after the injections, please let your doctor know as it may be best to change the date of the injections.
