I wonder if nurses always relay messages

But now here is what I'm wondering.  When I ask the nurse a question and she says she is going to ask the doc and call me back, the call back always makes me feel like my doc doesnt care. But whenI go in for my appointment and I ask the doc myself she always seems more than compasionate and understanding.  Is the nurse even relaying the question or message??

I dont always dislike the nurses, sometimes they seem really friendly and other times I feel like they must really have something against me.  I used to think they were like that because of the nature of pain management, to help weed out the drug seekers who find there way in. And they would lighten up after they got to know me. But I've been there for almost two years now, so now I only hope they know I'm not a drug seeker in the recreational sense of the word. I feel so lucky to have found the pain doc I have, she is a lovely woman.  And sometimes I really like the nurses too, but sometimes I want to shake the attitude right out of em. 

So my question is although I know they have to relay messages to the doc, does anyone else feel like maybe they really dont or do but not the way you asked it???
