Ultrasound-Guided Occipital Nerve Block in the Management of Refractory Headache and Its Outcomes: A Prospective Study

Abstract

Purpose Headache severely impacts health and lifestyle, causing distress and leading to accommodative changes in affected individuals. Treatment options available for refractory headache range from a conservative approach to advanced forms. The purpose of our study was to evaluate the effectiveness of ultrasound-guided occipital nerve block (ONB) in the management of refractory headaches using visual analog scale (VAS) score and Barrow Neurological Institute Pain Intensity Score (BNIPIS).
