The principle mechanism of post lumbar puncture headache is the leakage of CSF from the dural puncture site. This leads to a state of low sub-arachnoid pressure, causing traction on pain-sensitive intracerebral structures. ⋯ Traditional therapies such as bed rest and rehydration are usually ineffective when headache is severe. If this is the case, and the diagnosis is certain, a blood patch procedure can be performed, and repeated if necessary.
