Abstract
Greater Occipital Nerve (GON) and Multiple Cranial Nerve (MCN) blocks using local anaesthetics and corticosteroids have been used to treat various headache syndromes including Trigeminal Autonomic Cephalgias (TAC). We report cases where low cortisol levels have been seen in patients with TAC treated with GON/MCN blocks that included triamcinolone.
