The GON block is an injection containing a small dose of Depo-Medrone – a combination of local anaesthetic and a steroid – injected around the greater occipital nerve, which travels up each side of the back of the head. It works by reducing or blocking the signals sent by the greater occipital nerve, which can significantly improve symptoms of chronic headaches and migraines.
At the Royal Wharf Clinic here in London, we offer specialist assessment and treatment of migraines and their associated symptoms. Our process involves a comprehensive evaluation followed by a simple outpatient injection performed by one of our registered doctors. If you are one of many unfortunate sufferers of migraines which are rarely relieved by the administration of oral medication or a change of lifestyle, then give us a call to find out more about how our GON block migraine treatment works and how we can help.
Our doctors here at the Royal Wharf Clinic in London have been trained to administer a greater occipital nerve (GON) block for migraine treatment.
The entire procedure takes only a few minutes to complete, but we may need to monitor you for a short while to ensure you feel well enough to go home.
Most people can go home 15-20 minutes after their treatment. You may experience some dizziness, nausea, or pain for a short while after your injection, which is entirely normal. Some people can feel the effects of the nerve block within the first 15-30 minutes, whereas for others, it may be a couple of days. The injections should last for 4-12 weeks, depending on how your body has reacted to the nerve block. It is common to receive 3-4 injections per year to maintain the pain-relieving effect of the GON block.
