"Appalled" is the perfect word, 4-eyes! It is clear that you are as outraged as I.

"... but if I stayed in the hospital I might end up with a spinal tap and I didn't want that because it could result in paralysis. OMG!"

There is no time, nor venue, nor circumstance, where this comment is acceptable. And further, if I could speak to this sorry excuse of a "wanna be psychologist" we would have a little talk about his profound lack of intelligence because there is no right answer or action to his comment/question about the puncture. And worst of all, he hit someone when they were down...and that....is unforgiveable.
