A nerve block, assessed within the Neurology Department of MediHeart Medical Center in Morphou, is an injection treatment that can form part of the treatment plan for some types of headache and nerve-related pain in suitable patients.
What Is a Nerve Block?
A nerve block is an injection of local anaesthetic around a specific nerve involved in transmitting pain; sometimes a corticosteroid is added. The aim is to reduce pain signals travelling along that nerve and so ease the intensity or frequency of pain.
One of the most common nerve blocks in neurology is the greater occipital nerve block, given at the back of the head. Blocks of the lesser occipital nerve and some facial nerves may also be considered in selected patients.
When May a Nerve Block Be Used?
- Migraine (especially frequent or chronic migraine)
- Cluster headache
- Occipital neuralgia
- Cervicogenic (neck-related) headache
- Some headaches that have not responded well to other treatments
A nerve block is usually not used alone, but combined with medication, lifestyle measures and other preventive treatments.
Before the Procedure
- The type, frequency and duration of headache are assessed
- A detailed neurological examination is performed
- Your medicines are reviewed, especially blood thinners
- Allergies are checked
- Further tests are planned if needed
Infection at the injection site, allergy to local anaesthetics and certain skull defects may rule out the procedure; people with bleeding disorders need special assessment.
How Is It Done?
- You sit or lie in a suitable position
- The injection point is identified using anatomical landmarks
- The skin is cleaned
- A small amount of medicine is injected around the nerve with a fine needle
- You are observed for a short time afterwards
The procedure usually takes a few minutes in the clinic, and most people return to normal activities shortly afterwards.
When Does It Work and How Long Does It Last?
Some patients feel relief soon after the injection. How long the effect lasts varies widely, from hours to weeks and sometimes longer. Not everyone responds in the same way, and the procedure can be repeated at intervals if appropriate.
Possible Side Effects
- Pain, tenderness or redness at the injection site
- Local numbness
- Mild dizziness
- Minor bruising
More serious complications are rare, which is why the procedure should be performed by an experienced physician. Contact your doctor if any unexpected symptom develops.
Other Options in Migraine Care
Treatment is individual. In suitable patients with chronic migraine, migraine Botox may also be considered. For general information, see our Migraine and Headache Treatment page.
Frequently Asked Questions
Does a nerve block hurt?
A fine needle is used, so most people feel only a brief, mild sting.
Will a nerve block cure my migraine?
No. It does not cure migraine, but in suitable patients it may help reduce the intensity or frequency of headaches. Responses vary.
Can I drive afterwards?
Most people can return to normal activities after a short observation. If you feel dizzy, avoid driving until it passes.
How often can it be repeated?
Your doctor decides based on your response, the medicine used and your general health.
Conclusion
A nerve block is a short, generally well-tolerated procedure that may be added to the treatment plan for migraine, cluster headache and occipital neuralgia in suitable patients. At MediHeart Medical Center, the decision is made after a detailed neurological assessment. Patients from Morphou, North Cyprus and across Cyprus can contact us for appointments.
