My lumbar puncture did not hurt at all. I give credit to this for the highly skilled neurologist who did it. He was good at other things, too, like prescribing magnesium for jerks and spasm when I could not take Baclofen or Zanaflex. I didn't realize at the time how good he was, as that was fairly early in my diagnosis. I don't remember his name but he was James, a doctor at Scripps, now retired so you can't go see him, but I had lots of luck at Scripps in San Diego.
I am not lying. No pain with lumbar puncture. No headache afterwards. It was the doctor's skill.
