In general, recovery after lumbar puncture is 1-3 days. Some patients may recover relatively slowly, but most will not exceed 7 days. Lumbar puncture is mainly used to diagnose infectious diseases of the central nervous system and to measure the pressure of the cerebrospinal fluid. The operation involves inserting a puncture needle through the lumbar space into the subarachnoid space to extract part of the cerebrospinal fluid for laboratory testing. After lumbar puncture, dizziness and headache will be restored after the body’s autonomic adjustment to restore the balance of cerebrospinal fluid, which takes about 1-3 days. After lumbar puncture, it is recommended that the patient lie flat on the pillow for 6 hours to relieve low cranial pressure headache. In addition, if the patient himself has intracranial hypertension, brain herniation or intracranial occupying lesions, lumbar puncture should not be performed to avoid serious consequences.
