I have a horror story for you. Mine was ordered by the first neuro I saw who ordered all of the expensive testing but did not share results with me. The day after my lumbar puncture, one leg was so weak that I could not walk on it. I called and left messages for the neuro but he couldn't be bothered. I learned on the internet that temporary paralysis can occur and hoped for the best. To this day, I have a weak leg that worsens during flare-ups as a result of my lumbar puncture.
