Abstract
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). Methods A study sample of 30 eligible patients with refractory headaches including occipital neuralgia, migraine, tension headache, cluster headache, and vascular headaches aged between 18 and 65 years were included in our study. VAS and BNIPIS were noted for each patient before and after the procedure. ONB was given around the target nerve under aseptic precaution. Two milliliters of 0.5% bupivacaine was used as an injection solution for all patients. Results The mean VAS score in acute pain at pre-treatment and post-treatment after 24 hours and 3 months was found as 7.53, 1.53, and 3.20, whereas in chronic pain the score was 8.13, 3.07, and 5.87, respectively. Pre-treatment pain levels in acute and chronic subjects in BNIPIS IV and V category shifted to category I and II after 24 hours (postinjection) that later were recorded II and III, respectively, after 3 months. Conclusion Standard treatment guidelines are given by the international headache association for the management of headaches. The use of ONB is well advocated and practiced for a long time. In our study, we found that the use of greater occipital nerve block reduced pain levels affecting VAS and BNIPIS, which was more effective in acute cases than in chronic cases.
