I'm a redhead and yes theres some truth to this. It seems to me that I hear
a lot more about this than I used to. I always need more numbing than normal
when I go to the dentist, so does my daughter (also a redhead). I wake up
from anesthesia faster than most people. Pain is harder to get controlled. I
haven't read up on it recently but it does have to do with the recessive gene
that makes us redheads to begin with. I have a sister in the nursing home
with MS and some of the nursing staff is beginning to become familiar with it.
I guess maybe the medical staff just hasn't been informed. I do think the info
is becoming more common though.
