Myoclonus is one of the rare complications after the neuroaxial blockade. We report a patient who developed propriospinal myoclonus following cervical epidural steroid injection. An outpatient, 73-years-old man, complaining of a tingling sensation from the right shoulder of supraspinatous region to the ipsilateral hand, particularly along the C6 dermatome, visited our pain clinic center. In cervical magnetic resonance imaging scan, the disc between 6th and 7th cervical vertebrae was herniated and pressed the nerves to the right side. We performed cervical epidural steroid injection, using triamcinolone acetonide 40 mg with 0.25% bupivacaine HCL 5 ml. After the first injection, he had no problem, but following the second injection, myoclonic movements were developed and lasted for 6 hours along only the right side of the whole body without other neurologic complications. The myoclonic movement improved by intravenous injection of clonazepam 0.5 mg and the patient completely recovered without any neurologic sequelae on that day.
