Hiccups are generally benign and self-limited; however, sometimes they can be persistent and resistant to treatment. Diverse causes of persistent/intractable hiccups have been identified, including medications, a central nervous system pathology, malignancy, and metabolic abnormalities. Neural blocks are a well-known treatment option for chronic lower back pain and are usually indicated in acute and chronic lower back pain. When used in a careful manner with close monitoring, side effects are uncommon and transient; hence, the neural block procedure is considered a safe therapeutic intervention. We present a case of persistent hiccups after a selective nerve root block in a patient with a herniated lumbar disc. A literature review on underlying mechanisms is provided and specific therapies for management are recommended.
