Danny, I understand your frustration completely. It is amazing to me how many doctors try to hide their ignorance, or indifference, by being arrogant and talking down to you. I had an experience that was a little bit similar to yours when I went to my family doctor to get clearance for surgery by Dr. Gross. I have been a patient of my family doctor for over 20 years, and he is very good in his own area of expertise, but he was not happy about the fact that I was having Dr. Gross do the surgery, because he does not know him and thought I had just found him on some website. (Anyone can create a website and make all kinds of claims...) Also, he did not think some of the test requested were necessary. He even asked me if my hip was really hurting badly enough that I needed surgery! Because I know this doctor, and therefore know that most of this came from concern over my wellbeing, it was not as upsetting as it could have been. However, I think some of it was because I had not consulted him in choosing my surgeon! Fortunately, because I live in the US and have good insurance through my work, I can consult any surgeon I want to without a referral from anyone.
I am confident, based on what Pat says, that you will have better luck with Mr. Treacy!
