Hi, here is some quoted matter for your perusal and please visit the websites.
“Headache after LP is common, usually occurring hours to a day or 2 afterward, and can be debilitating. Younger patients with small body mass are at greatest risk. Using smaller, noncutting needles decreases risk. The amount of CSF removed and duration of recumbency after LP do not affect incidence.
The 1st line of treatment is recumbency, hydration, an elastic abdominal binder, mild analgesics, and caffeine. If post-LP headache persists after a day of such treatment, an epidural blood patch (injection of a few mL of the patient's clotted venous blood into the lumbar epidural space) is usually effective. Spontaneous CSF leaks rarely require surgical closure”. Taken from website
“Headache following a lumbar puncture is a common and often debilitating syndrome. Continued leakage of cerebrospinal fluid from a puncture site decreases intracranial pressure, which leads to traction on pain-sensitive intracranial structures. The headache is characteristically postural, often associated with nausea and optic, vestibular, or otic symptoms. Although usually self-limited after a few days, severe postural pain can incapacitate the patient. Management is mainly symptomatic, but definitive treatment with the epidural blood patching technique is safe and effective when done by an expert operator”. Taken from website
