What Is a GON Block and Can It Relieve Migraine Pain Quickly?
A Greater Occipital Nerve (GON) block is a minimally invasive procedure used for rapid relief and short-term prevention of pain arising from headache disorders, migraine disorders, and cephalgia. The injection delivers local anaesthetic — and in some cases a corticosteroid — directly around the greater occipital nerve, interrupting the pain signals associated with many headache conditions.
This treatment is particularly effective for patients who need bridging relief while longer-term migraine treatment strategies take effect. It is performed in clinic and typically takes only a few minutes, with many patients noticing improvement within 24–72 hours.
Suitable for: Migraine disorder, chronic daily headache, occipital neuralgia, and related cephalgia conditions.
