RT Journal Article SR Electronic T1 Another cause of headache after epidural injection JF Neurosciences Journal JO Neurosciences (Riyadh) FD Prince Sultan Military Medical City SP 167 OP 169 DO 10.17712/nsj.2015.2.20140769 VO 20 IS 2 A1 Jamil S. Anwari A1 Abdulaziz A. Hazazi YR 2015 UL http://nsj.org.sa/content/20/2/167.abstract AB Headache is a potential complication of epidural injection. We report a patient who developed headache 5 days after a lumbar epidural steroid injection, which was not related to the epidural procedure, but caused by Duloxetine induced hyponatremia. Antidepressant drug induced headache should be considered in the differential diagnosis of post dural puncture headache.
