A spinal puncture, or lumbar puncture, is a procedure where a doctor inserts a small needle into the lower back to collect cerebrospinal fluid (CSF). This fluid surrounds your brain and spinal cord, helping diagnose conditions like infections (such as meningitis), nerve disorders (like multiple sclerosis or Guillain-Barré syndrome), or bleeding in the brain. In some cases, this procedure is also used to deliver medications directly into the CSF.

For the procedure, you will lie on your side or sit up while the doctor numbs the area with a local anesthetic. A thin needle is carefully inserted between the spine’s bones to reach the fluid. While this may sound uncomfortable, most people feel only minimal discomfort.

This procedure helps diagnose symptoms like persistent headaches, fever, or unexplained neurological issues. Alternative options may include blood tests, CT scans, or MRIs, but a spinal puncture provides the most direct information about CSF-related conditions.

Risks are rare but can include headaches from fluid leakage, which usually improve with rest and hydration. More serious complications, like infection or bleeding, are uncommon. Afterward, you’ll need to lie flat for a couple of hours to help minimize headaches.

If a spinal puncture isn’t suitable, other options like imaging tests, nerve studies, or symptom-based treatment may be considered. However, in many cases, this procedure is the most accurate way to diagnose central nervous system disorders and can also be used to administer specialized therapies.
