Hmm, I think I would try to find a more cooperative primary care Dr.
It doesn't sound like he is "involved" or actively working to give or find the best care for you.

You shouldn't have to feel like you are pulling teeth to get some blood tests.

I wish someone had suggested this to me - when I wasn't getting the best care from my doc for my RSI and comp claim. I should have found a better doc & a better atty.

ask around, make calls and check your med ins website for doctors listings-
it doesn't hurt to check around and get some names to consider.
