My DS has huge fear of needles, but the blood draw was worse than the LP for him. The NIH had the whole team (5) people in there for the LP. They are professional with these kids! They numbed the area, but no anesthesia. They let him continue his game on the xbox and that seemed to keep him occupied enough to do the proceedure. Of course I couldn't be in the room while they did it so I have to take their word on it. :-) I am in agreement though that it seems a little much for a folate level... I was just reading on hair testing for tissue mineral/nutrients though I don't know much about it yet.
