Post-dural puncture headache (PDPH),recognized as one of the most frequently observed complications of spinal anesthesia,occurs due to cerebrospinal fluid (CSF) leakage from a defect in the dura mater formed because of a trauma.Generally,the pain is bilateral frontal,retroorbital,or occipital,which radiates toward the neck.Most characteristic feature of PDPH is its postural nature.It aggravates by sitting or standing,whereas it declines or it is completely resolved by lying down.Generally,PDPH occurs within the 72 h after the procedure,and if it\'s untreated,it may last for several weeks.
