Which of the following is associated with an increased risk of post lumbar puncture headache?

Greater volume of CSF collected was associated with increased risk of immediate postprocedural headache, largely owing to a nonlinear increase in risk on collection of volumes above 30 mL (odds ratio, 3.73 for >30 mL and 0.98 for <17 mL).

3. Replacement of stylet before withdrawal of spinal needle.
4. Early ambulation, NOT laying flat post procedure.

When does post dural headache occur?

PDPH typically occurs hours to days after puncture and presents with symptoms such as headache (which is mostly bi-frontal or occipital) and nausea that typically worsen when the patient assumes an upright posture. The headache usually occurs 24–48 hours after puncture but may occur as many as 12 days after.
