Does waist piercing hurt the body?

"Lumbar puncture" is a common name, which is a technical means to obtain cerebrospinal fluid samples through spinal cord puncture. Cerebrospinal fluid is produced by the choroid plexus in the ventricular system. It is filled with fluid in the ventricle and subarachnoid space, and surrounds the brain and spinal cord. It has functions such as protecting the brain and spinal cord from external mechanical damage and regulating intracranial pressure. The purpose of cerebrospinal fluid puncture is to check for intracranial hemorrhage, meningeal irritation, leukemia brain metastases, and certain neurological symptoms.

Cerebrospinal fluid needs to be obtained by lumbar puncture. Generally, the patient is required to lie on the side on the flat bed, and bend the body as much as possible to expand the lumbar vertebrae. Doctors generally perform local anesthesia before puncture, and measure the pressure during puncture. The extracted cerebrospinal fluid samples can generally be used for routine examinations, biochemical examinations, immunological examinations, and bacterial culture examinations. The amount of cerebrospinal fluid extracted is generally about 4 to 6 ml, and the cerebrospinal fluid specimen is a colorless and transparent water-like liquid under normal conditions.
