My pcp is up for every test in the book too - and he's one of the old school guys too, like yours.
Can you talk to him? Really talk?
I will tell my doc, if my gut says this isn't anything serious, can we just wait and see? And he'll just go with that usually.
That's the rock and the hard place. With the older ones, you have to back them off a little. With the younger ones, I feel like I'm gonna have to wait for Dr. G, Medical Examiner to figure me out.
