I underwent my first spinal tap two weeks ago, I carry some emotional baggage from some procedures now carried out nearly sixty years ago (spinal fusion and confinement to a body cast) so I'll readily admit that I objected (and forcefully) at the mention of the term "lumbar puncture". An hour's wait after "gowning up" didn't do much to put me at ease.
But from there on, everything turned around.
After signing the official release, I was given 5 mg of Lorzepam and invited to sit on the treatment table while the procedure was explained; the "table" turned out to be a state-of-the-art fluoroscope, which would be used to guide the needle and avoid penetrating any of the places where it could really hurt (very much appreciated in my case since the previous surgery left my spine far from normally-formed).
A shot of Novocain or lidocaine was then administered while lying on my stomach, followed by the extraction needle;
I felt virtually nothing. Removal of about 30 cc of spinal fluid took another two minutes or so, during which I was able to hold a conversation with the MD in charge. The site of the puncture could be covered with a small "spot" (circular) Band-AId.
ONE SMALL BIT OF FRIENDLY ADVICE TO THE MEDICAL PROFESSION: Some of us have been able to avoid the "rougher" side of medical procedures for a long time, but the memories can linger. So when scheduling a test or treatment that has been made easier and a lot less painful, please be sure that this is fully communicated to someone "my age", and not by a Pollyanna-type barely into her twenties.
