Any headache?: #1 adverse effect of lumbar puncture is post-procedure headache, which is treated with lying flat and drinking lots of water besides the pain meds. Back pain where the LP was done, if persistent beyond 48 hrs, may indicate infection, but more likely nerve involvement during the procedure. Mental lethargy should not happen unless you had meningitis. Was meningitis what LP was done for? ...Read more

Positional: In the side-lying position intracranial pressure as measured during lumbar puncture should be between 100 and 150 cm of water pressure. If pressure is measured while sitting upright, pressure level in fluid column should extend to base of skull (foramen magnum) but numerically will exceed 150. The rest of your question is unclear.

I have positional pulsitive tinnitus with headpain I'm scheduled for an IR Lumbar Puncture. If not symptomatic at time of LP am I wasting my time?

My understanding: is that lumbar puncture may sometimes be helpful for both diagnostic reasons as well as therapeutic in idiopathic intracranial hypertension a symptom of which may be pulsatile tinnitus. In some cases the relieving of pressure during the LP improves, at least transiently, the symptoms. I wouldn't think you would have to be having symptoms for it to work, but if no symptoms then, how will you know? ...Read more
