My PCP is a jerk cont..
I find out a lot more about stuff from reading, other people, my surgeon's staff, etc.
Vitamin D was "the big thing" a few years ago. I was depleted (Seattle) and needed huge amounts of prescription Vitamin D. Funny now I live in the same place, with the same lack of sun, but she doesn't test for Vitamin D any more. I guess it's not "the big thing" any longer.
