- How long does it take? The LP takes approximately 20 to 30 minutes, with an additional 30 minutes to rest after the procedure.
- Does it hurt? You can expect pressure when the needle is inserted and may experience brief leg pain while the needle is positioned.
- Can I be paralyzed if the needle hits the spinal cord? No. The needle is inserted below the spinal cord. There is no risk of paralysis.
- What are the side effects of a LP? During the procedure, you may have temporary back pain and/or discomfort. After the procedure, you may have a headache. There are other side-effects that are uncommon, which our physician can discuss with you.
- How is the lumbar puncture performed? You will either lie on your side, with your knees drawn up or you will sit on the edge of the exam table. A local anesthetic may be given at the puncture site. A needle is inserted into your back to collect the spinal fluid.
