A. The most important thing for you to do is to remain still in a “fetal position”. Bend your knees and thighs and flex your head and trunk as much as you can, so that you are in a “fetal position”. This position will open up the space between the vertebrae for easy introduction of the spinal needle into the cerebrospinal space (watch the video for correct positioning). Once the procedure is finished, lay on your back for at least four hours. Inform the physician if you have headache, fever, chills, or redness at puncture site.
