What is a spinal tap and how is it related to multiple sclerosis?

ANSWER

Your brain and spinal cord are bathed in fluid. A spinal tap, also called a lumbar puncture, is a procedure doctors use to remove and test some of this liquid, called cerebrospinal fluid (CSF).

It helps them diagnose disorders of the brain and spinal cord, including multiple sclerosis.
