Greater occipital nerve (GON) block is widely used for treating primary and secondary headache disorders and is generally considered safe. Nevertheless, unexpected adverse effects may occasionally occur. We describe a 45-year-old man with migraine who developed persistent hiccups following bilateral ultrasound-guided GON block. The procedure was performed in the prone position using an in-plane approach to target the GON between the obliquus capitis inferior and semispinalis capitis muscles. A total of 4 mL of 0.5% bupivacaine with dexamethasone (4 mg per side) was injected. No immediate complications were noted, but continuous hiccups developed nine hours later. Clinical and laboratory evaluations excluded common etiologies such as reflux, metabolic disorders, and central nervous system pathology. Supportive measures were provided, and symptoms resolved spontaneously within 48 hours. To our knowledge, this is the first report of hiccups after GON block. Clinicians should be aware of this rare but distressing outcome.

Büyük oksipital sinir (GON) bloğu, primer ve sekonder baş ağrılarının tedavisinde yaygın olarak kullanılan ve genellikle güvenli kabul edilen bir girişimdir. Bununla birlikte, nadir ve öngörülmeyen yan etkiler görülebilir. Bu olgu sunumunda, bilateral ultrason kılavuzluğunda GON bloğu sonrası inatçı hıçkırık gelişen 45 yaşında migrenli bir erkek hasta sunulmaktadır. İşlem pron pozisyonda, in-plane yaklaşım ile obliquus capitis inferior ve semispinalis capitis kasları arasındaki GON hedeflenerek gerçekleştirildi. Her iki tarafa 4 mg deksametazon içeren toplam 4 mL %0,5 bupivakain enjekte edildi. İşlem sonrası erken dönemde komplikasyon gözlenmedi; ancak yaklaşık dokuz saat sonra başlayan sürekli hıçkırık 48 saat boyunca devam etti. Klinik ve laboratuvar incelemeleri, gastroözofageal reflü, metabolik bozukluklar ve santral sinir sistemi patolojilerini dışladı. Destekleyici tedavi uygulanmasının ardından semptomlar spontan olarak geriledi. Bildiğimiz kadarıyla bu, GON bloğu sonrası bildirilen ilk inatçı hıçkırık olgusudur. Klinik uygulamalarda bu tür nadir yan etkilerin göz önünde bulundurulması önemlidir.
