Headache can be just a symptom of many diseases, or sometimes it is a separate disease. Cerebrospinal fluid testing is one of the paraclinical methods used to find the cause of headache.

Cerebrospinal fluid is the fluid surrounding the brain and spinal cord. If the doctor thinks the patient has a disease that affects the nervous system, the patient will be ordered a cerebrospinal fluid test.

Cerebrospinal fluid is the fluid surrounding the brain and spinal cord, which plays an important role in taking essential supplies from the blood and removing waste products from brain cells, protecting brain cells.
